+<P>
+<A NAME="IDX1"></A>
+<CODE>Pcb</CODE> is a handy tool for laying out printed circuit
+boards.
+It was first written for an Atari ST in 1990 and ported to <CODE>UNIX</CODE> and
+<CODE>X11</CODE> in 1994.
+I never had the intention to create another professional layout system,
+but to write a tool which supports people like you who do some
+home-developing of hardware. For this reason it has no auto-router nor
+auto-placement code.
+
+
+<P>
+The second release 1.2 included menus for the first time. This made
+<CODE>PCB</CODE> easier to use and thus a more important tool.
+
+
+<P>
+Release 1.3 introduced undo for highly-destructive commands,
+more straightforward action handling and scalable fonts. Layer-groups
+were introduced to group signal-layers together.
+
+
+<P>
+Release 1.4 provided support for add-on device drivers.
+Two layers (the solder and the component side)
+were added to support SMD elements. The handling of libraries
+was also improved in 1.4.1. Support for additional devices like
+GERBER plotters started in 1.4.4. The undo feature was expanded
+and the redo-feature added in 1.4.5.
+
+
+<P>
+Release 1.5 provides support for rats-nest generation from simple net
+lists. It also allows for automatic clearances around pins that pierce
+a polygon. A variety of other enhancments including a Gerber RS274X
+driver and NC drill file generation have also been added.
+harry eaton (haceaton@aplcomm.jhuapl.edu)
+was responsible for most of the changes found in this release.
+
+
+<P>
+Release 1.6 provides automatic screen updates of changed regions.
+This should elliminate most of the need for the redraw (r) key.
+Also some changes to what order items under the cursor are selected
+were made for better consistancy - it is no longer possible to
+accidentally move a line or line point that is completely obscured
+by a polygon laying over top of it. Larger objects on the upper
+most layers can be selected ahead of smaller objects on lower layers.
+These changes make operations more intuitive. A new mode of line
+creation was added that creates two line on 45 degree angles
+with a single click. The actual outline of the prospective line(s) are
+now shown during line creation. An arc creation mode was added.
+Drawn arcs are quarter circles and can be useful for high frequency
+controlled impedance lines. (You can have eighth circle arc if the
+source is compiled with -DARC45, but be aware that the ends of such
+arcs can never intersect a grid point). Two new flags for pins and
+vias were created - one indicates that the pin or via is purely a
+drill hole and has no copper annulus. You can only toggle this flag
+for vias - for elements, it must be an integral part of the element
+definition. The other flag controls whether the pad will be round
+or octagonal. There is also now a feature for converting the contents
+of a buffer into an element. Vias become the pins (or mounting holes),
+lines and arcs on the solder layer become silkscreen, and lines on the
+component layer become the pads. Action commands entered via the colon
+command entry are no longer proceeded with "a ", just type the command
+directly. Several bugs have also been fixed. New
+ones were probably introduced since extensive changes were made.
+harry eaton was responsible for these changes.
+
+
+<P>
+Release 1.6.1 adds the ability to make groups of action commands bound to
+a single X11 event to be undone by a single undo. Also a simple design rule
+checker was added - it checks for minimum spacing and overlap rules. Plus
+many fixes for bugs introduced with the many changes of 1.6
+harry is responsible for these changes too.

+<P>
+Each layout consists of several, mostly independent, objects. This chapter
+gives an overview of the object types and their relationship to each other.
+For a complete description of how to use <CODE>Pcb</CODE>, refer to
+section <A HREF="pcb.html#SEC12">Getting Started</A>.
+The layout is generated on-screen on a grid that has its origin in the
+upper left corner of the screen.
+The x coordinate increases to the right, y increases down to the bottom.
+All distances and sizes in <CODE>Pcb</CODE> are measured in mils (0.001 inch).
+One unit on the display grid is one mil in distance on the board.
+The sections in this chapter are sorted by the
+order of appearance of the objects within a layout file.

+<H2><A NAME="SEC4" HREF="pcb_toc.html#TOC4">Symbols</A></H2>
+<P>
+The top object is the layout itself. It uses a set of symbols
+that resides at the first logical level. Each symbol is uniquely identified
+by a seven bit <CODE>ASCII</CODE> code. All layout objects share the same set of
+symbols. These symbols are used to form text objects on the silkscreen
+and copper layers. Undefined symbols are drawn as filled rectangles.
+
+
+<P>
+Every font file is preprocessed by a user-defined command when it is loaded.
+For details see <SAMP>`fontCommand'</SAMP>, section <A HREF="pcb.html#SEC41">Non-Standard X11 Application Resources</A>.

+<A NAME="IDX5"></A>
+
+
+<H2><A NAME="SEC5" HREF="pcb_toc.html#TOC5">Vias</A></H2>
+<P>
+Vias are identical to the pins used by elements except that they can be added
+or removed individually.
+The purpose of vias is to provide connections between different layers.
+Don't use vias for adding elements to the layout, even if that seems
+easier than creating a new element.
+Vias are useful for defining arbitrary drill points such as
+those used for mounting a board.
+You can assign a name to a via even though you probably won't ever want to.
+Vias reside at the first logical level; therefore, each
+via exists on all layers. (<EM>i.e.</EM>
+blind vias are not supported)
+
+
+<P>
+<A NAME="IDX6"></A>
+<A NAME="IDX7"></A>
+
+
+<H2><A NAME="SEC6" HREF="pcb_toc.html#TOC6">Elements</A></H2>
+<P>
+Elements represent the components on a board.
+Elements are loaded from <CODE>ASCII</CODE> coded files in a
+similar manner to the layout file itself.
+They are composed of lines and arcs on the silk-screen
+layer (used to define the package outline) , pins
+(or pads for SMD) and three labels that define the
+description, the element's layout-name (which also
+appears on the silk- screen layer) and its value.
+Element pins are contained on the first logical level
+and so reside on all layers.
+A mark is used to position the element with
+respect to the cursor cross-hair during pasting.
+SMD elements use pads instead of pins.
+Pads are handled similarly to lines on a layer but they must be oriented
+either vertically or horizontally.
+Pads can have either rounded or square ends.
+All parts of an element are treated as one unit.
+It is not possible to delete a single pin or break
+an element into pieces on the layout.
+You can resize separate pieces of an element,
+but doing so is usually a bad idea.
+
+
+<P>
+Elements are supported by several special layers: <EM>silk</EM>, <EM>pins/pads</EM> and
+<EM>far-side</EM>. The <EM>silk</EM> layer shows the package outline and
+also holds legend text and element names. The <EM>pins/pads</EM> layer is used to toggle
+whether the element's pins and pads are displayed. The <EM>far-side</EM> layer controls visibility
+of objects (silkscreen and pads) that are on the far (<EM>i.e.</EM> not currently viewed) side
+of the board.
+
+
+<P>
+Every element file is preprocessed by a user-defined command when the file is read.
+For details see <SAMP>`elementCommand'</SAMP>, section <A HREF="pcb.html#SEC41">Non-Standard X11 Application Resources</A>. <CODE>m4</CODE>, the default
+value of <SAMP>`elementCommand'</SAMP>, allows you to create libraries for
+package definitions that are shared by all elements.
+The element libraries distributed with <CODE>Pcb</CODE> expect <CODE>m4</CODE> or an
+equivalent to be the <EM>elementCommand</EM>.
+
+
+<P>
+<CODE>Pcb</CODE> can create a list of
+all connections from one (or all) elements to the others or a list of
+unconnected pins.
+It can also verify the layout connections against a netlist file.
+The element's <SAMP>`layout-name'</SAMP> is the name used to identify an element
+in a netlist file.
+The pin numbering for an element is defined by unique strings assigned to
+each pin. In addition to the "pin number" string, each pin has a "name"
+which describes its function. Previously element pin number was established
+by the order of appearance of the pin definitions in the layout or element
+file. Since the "number" strings for each pin are a new feature, if they are
+absent then the numbering is again established by the order of pin appearance
+in the file.
+In other words, the first pin appearing in the file is pin one, the
+next pin is pin two and so on.
+Usually the names assigned to pins are simply numbers, but they don't
+have to be. It is only necessary that the "number" string for the pin
+matches exactly the "number" string in the netlist file.
+<B>Be aware that a few of the library parts may still be incorrectly
+implemented regarding pin-numbering.</B> All of the DIL (Dual-
+Inline-Pins) parts are correct and most of the others are too,
+but you should verify the pin numbering
+of any non-DIL part (use the <EM>Report Menu</EM> to see what <CODE>Pcb</CODE> thinks a pin's
+number is) before using the rats nest feature with a library part. Hopefully sometime
+soon someone will volunteer to cross-check all of the element libraries and make
+fixes available as necessary.
+<CODE>Pcb</CODE> can also check a layout to see that it meets minimum spacing
+and overlap rules.
+
+
+<P>
+You can make your own quick-and-dirty element definitions graphically now.
+Simply draw vias for the pins
+and lines and arcs on a solder layer for the silkscreen
+outline. You should name each via with the pin number.
+If you want to create a SMD device, draw lines for the pads on a
+component side layer (You must draw these in pin number order since lines can't
+be named). They must be
+either horizontal or vertical or they will not be recognized as pads. Once
+you are happy with the geometry, select everything that is to become part of
+the element, then choose "cut to buffer" from the menu. Now select "convert
+buffer to element" from the menu. Viola'! Afterwards you can make pin one
+square (or pads) if you like, and give the element its various names. Note that the
+element mark corresponds to the cut position when everything was put into the
+buffer. If the vias are not named, then the pin numbering will correspond to the
+order in which the vias were placed.

+Every layout consists of several layers that can be used independently
+or treated as a group.
+Layer groups can be used to logically separate (and color-code)
+different traces (<EM>e.g.</EM> power and signal); however, all
+layers within a group reside on the same physical
+copper layer of a board, so using different layers within the same
+group won't provide electrical separation where they touch or overlap.
+For details, see <SAMP>`layerGroups'</SAMP>, section <A HREF="pcb.html#SEC41">Non-Standard X11 Application Resources</A>.
+Each layer is drawn in a color defined in the resource file (for
+details see <SAMP>`layerColor'</SAMP>, section <A HREF="pcb.html#SEC41">Non-Standard X11 Application Resources</A>) and identified by a name
+that you can change.
+Layers are really just containers for line, polygon, and text objects. The
+component and solder layers contain SMD elements as well, but the
+file structure doesn't reflect that fact directly. Each layer group
+represents a physical layer on the printed circuit board. If you want to make
+a four layer board, you'll need to have four layer groups.
+Connections between layer groups are established only through element pins and vias.
+The relationship between a specific layer and the board itself is configureable from
+the <SAMP>`Edit layer groups'</SAMP> option in the <SAMP>`Objects'</SAMP> menu.
+The layer groups corresponding to the physical layers <EM>component-side</EM>
+and <EM>solder-side</EM> are always defined, and you must map at least one
+logical layer to each.
+Of course, you are not obligated to put tracks on either of them.
+SMD-elements always reside on either the component-side or the solder-side
+layer group.
+You can swap which side of the board you are viewing by pressing
+<EM>&#60;Key&#62;Tab</EM>.
+You can decide which layer group will be the solder side and which will be
+the component side.
+The layers groups just have a name or number associated with them - where
+they are sandwiched in the board is left to the manufacturing processes.

+<H2><A NAME="SEC8" HREF="pcb_toc.html#TOC8">Lines</A></H2>
+<P>
+Lines are used to draw tracks on the pc board.
+When in the line mode, each <EM>&#60;Btn1&#62;</EM>
+press establishes one end of a line.
+Once the second point is defined, the line is drawn
+and a new line started where the first one ended.
+You can abondon the new starting point in favor
+of another by pressing <EM>Ctrl&#60;Btn1&#62;</EM>.
+The undo function (<EM>&#60;Key&#62;u</EM>) will take you back
+point by point if you use it while in the line mode.
+New lines can be restricted to 45 degree angles if desired. You can toggle this
+restriction on and off while creating lines by pressing <EM>&#60;Key&#62;.</EM> (that is the
+<EM>period</EM> key). If the 45 degree restriction is turned on, then the <EM>&#60;Key&#62;/</EM>
+can be used to cylce through three different modes of 45 degree line creation.
+One mode just creates a single line forced to the nearest 45 degree vector. The next
+mode creates two lines from the start to end points such that the first line leaves the
+start point at a 90 degree vector, and the second line enters the end point on a 45
+degree vector. The next mode creates two lines such that the first line leaves the
+start point on a 45 degree vector and arrives at the end point on a 90 degree vector.
+You can temporarily swap between the last two modes by holding the shift key down.
+It is simple to edit a line type object by breaking it into pieces (insert point mode),
+moving an end point (or the whole line) (<EM>&#60;Btn2Down&#62;&#60;drag&#62;&#60;Btn2Up&#62;</EM>),
+or changing the layer it resides on (<EM>&#60;Key&#62;m</EM> moves the line under the pointer
+to the active layer).
+In the case when two line segments meet at exactly the same
+point you can delete the intermediate point, otherwise the delete mode removes an entire line.
+Feel free to experiment
+since <CODE>Pcb</CODE> will allow you to undo anything that materially affects your work.
+If you switch active layers in the midst of placing lines a via will automatically be
+placed, when necessary, in order to continue the connection.

+<H2><A NAME="SEC9" HREF="pcb_toc.html#TOC9">Arcs</A></H2>
+<P>
+With version 1.6 it is possible to draw copper arcs. The arcs are restricted to
+be quarter circles. This means they always bend a right angle. They are very similar
+to lines otherwise. They are created on the current layer and have the same thickness
+that new lines will have. The various clicks for creating lines work pretty much the
+same way for creating arcs. The start point for the arc is at the first <EM>&#60;Btn1&#62;</EM>
+position. In order to make the arc curve in the direction desired, drag the mouse along
+the tangent line from the starting position towards the end position. If the grid is
+too coarse, it may not be possible to distinguish whether you've moved over then up,
+or up then over, so if you can't seem to make the arc go the direction you want, you
+should decrease the grid spacing. Alternatively you could drawn the wrong arc, then
+rotate and move it where you want. Like the line tool, after an arc is drawn a new
+starting point is established at the end point. Whenever a start point is established
+by either the line or arc tools it will be retained if you switch directly between the
+tools (e.g. <EM>&#60;Key&#62;F2</EM> for Lines, <EM>&#60;Key&#62;F8</EM> for Arcs. Of course connection
+searches, undo and all the other features you'd expect work with arcs now.

+
+<H2><A NAME="SEC10" HREF="pcb_toc.html#TOC10">Polygons</A></H2>
+<P>
+Sometimes it's useful to fill large areas with solid copper.
+The way to do this is with polygons.
+Polygons can be created in either the polygon mode or the rectangle mode.
+In the polygon mode, you'll have to define each corner of the polygon
+with a mouse click (<EM>&#60;Btn1&#62;</EM>). When the last point is clicked
+exactly on top of the starting point, the polygon is finished.
+Since this can be hard to do, the <EM>Shift&#60;Key&#62;p</EM> will enter the
+final point for you, closing the polygon.
+If the 45 degree angle restriction is turned on
+and you try to close the polygon when it is not possible, you'll get a
+warning instead. If you haven't finished entering a polygon, but want to
+undo one (or more) of the points that you've already defined, use the
+undo command (<EM>&#60;Key&#62;u</EM>).
+With the rectangle tool, defining
+the two opposite corners is sufficient, but of course the resulting
+polygon is a rectangle.
+Like lines, a polygon can by edited by deleting, inserting and moving the points
+that define it.
+<CODE>Pcb</CODE> is capable of handling complex polygons, but
+using a number of simpler ones improves performance of the connection tracing code.
+
+
+<P>
+A new feature in version 1.5 of <CODE>Pcb</CODE> automatically creates clearance
+regions around pins and vias that pierce a polygon. This means that they
+aren't electrically connected to the polygon unless you add "thermals"
+to cross the clearance region.
+Thermals can be added and removed by selecting the thermal mode and clicking
+<EM>&#60;Btn1&#62;</EM> on the pin or via.
+Remember that this only creates connections to the polygon on the active layer.
+The great advantage to this new polygon behavior is that simple or complex ground
+and/or power planes can be easily made with polygons and seen on the screen.
+If you don't want this auto-clearance behavior, or you load a layout created by
+an earlier version of <CODE>Pcb</CODE>, the old behavior
+(shorts to all piercing pins and vias) is available. A <SAMP>`ChangeSize'</SAMP>
+operation (<EM>&#60;Key&#62;s</EM>) toggles a polygon between the new and old polygon/pin
+behavior.

+<P>
+Text objects should be used to label a layout or to put additional
+information on the board, but not to identify elements because elements
+have their own labels.
+Text is always horizontal when first created, but the
+rotate mode can align it along 0, 90, 180 and 270 degree angles.
+Text can be moved from any layer to the silk-screen layer with a
+command in the <SAMP>`selection menu'</SAMP>.
+Text that is moved to the silk-screen layer will appear on the
+solder-side silk-screen if it originating on a solder-side layer.
+Otherwise moving it to the silk-screen layer will put it on the
+component-side silk-screen.
+To move text back to a copper layer from
+the silk-screen, use the <SAMP>`MoveToCurrentLayer'</SAMP> (<EM>&#60;Key&#62;m</EM>) command.
+Text on the far side of the board will automatically appear mirror-imaged.

+The goal of this chapter is to give you enough information to learn how
+<CODE>Pcb</CODE> works and how to develop your layouts to make the best use of <CODE>Pcb</CODE>'s
+features. All event translations (<EM>i.e.</EM> the buttons and keys you
+press) refer to the default application resource file shipped with <CODE>Pcb</CODE>.
+There is probably no need to change them unless your window

+to customize the behavior of <CODE>Pcb</CODE> then changing the resource file
+is usually the best way to do it.
+
+

+The status-line is located at the bottom edge of the main window.
+During normal operation the status information is visible there.
+When a selected menu operation requires an additional button click, the
+status-line is replaced by a message telling you to position the cursor
+and click.
+When a text input is required, the status-line is replaced by the
+Input-field which has a prompt for the typed input.
+

+(abs) or relative (rel) grid is used, if new lines are restricted to 45 degrees,
+which type of 45 degree line mode is active, whether rubberband move and

+If a layer hasn't been named, the label "<EM>(unknown)</EM>" is used as the defualt.
+
+
+<P>
+The upper control box is used to switch layers on and off. Click
+<EM>&#60;Btn1Down&#62;</EM> on one or more of them. Each click toggles the setting.
+The currently active layer can't be switched off.
+The layout is refreshed when the pointer reenters the drawing area. This
+prevents excessive redrawing when the visibility of several layers is changed.
+When the layers are grouped, clicking on these fields will toggle
+the visibility of all layers in the same group. This is a good idea because
+layers in the same group reside on the same physical layer of
+the actual board.
+Use the <SAMP>`Edit layer groups'</SAMP> option in the <SAMP>`Objects'</SAMP> menu to
+change the layer groupings.
+Grouping layers is only useful for helping you to color-code
+signals in your layout. Note that grouping layers actually reduces the number
+of different physical layers available for your board, thus to make an eight
+layer board, you cannot group any layers.
+
+
+<P>
+<EM>far side</EM> turns on and off the visibility of elements
+(including SMD pads) on the opposite
+board side, as well as silk screening on that side. It does not automatically
+hide the x-ray view of the other copper layers, these must be turned off
+separately if desired. Use the <EM>tab</EM> key to view the entire board from the other
+side. To see a view of what the back side of the board will actually look like,
+make the solder layer the active layer then press <EM>tab</EM> until the status
+line says "solder" on the right, then turn off the visibility of all other layers
+except pins/pads, vias, and silk.

+Reset-mode is really no mode, and <EM>&#60;Btn1&#62;</EM> has no effect with
+this setting.
+Some of the modes are very simple, such as the via-mode. Clicking
+<EM>&#60;Btn1&#62;</EM> while in this mode creates a via at the cross-hair position.
+The pastebuffer-mode is similar. With this mode, <EM>&#60;Btn1&#62;</EM> copies
+the contents of the active buffer to the layout, but only
+those parts that reside on visible layers are copied.
+The rotate-mode allows you to rotate elements and text objects
+90 degrees counter-clockwise with each click.
+The line-mode is explained in detail in section <A HREF="pcb.html#SEC8">Lines</A>.
+The arc-mode is explained in detainl in section <A HREF="pcb.html#SEC9">Arcs</A>.
+Rectangle-mode, polygon-mode and thermal-mode are explained in detail in

+Remember that the thermal-mode will only create and destroy thermals
+to polygons on the active layer.
+
+
+<P>
+The insert-point-mode is an editing tool that allows you to add
+points into lines or polygons. With version 1.5 of <CODE>Pcb</CODE>, the
+insert-point-mode enforces the 45 degree line
+rule. You can force only the shorter line segment to 45
+degrees by holding the shift key down while inserting the point.
+The delete-mode deletes the smallest object beneath the cursor with each
+<EM>&#60;Btn1&#62;</EM> click.
+If you use click at an end-point
+that two lines have in common, it will replace the two lines with a single line

+<H2><A NAME="SEC21" HREF="pcb_toc.html#TOC21">Drawing and Removing Basic Objects</A></H2>
+<P>
+There are several ways of creating new objects: you may draw them yourself,
+you may copy an existing object or you may load an element from a file or
+library. Creating new objects is normally related to a special
+mode depending on the object type.
+The notation of key and button events is the same as described in the
+X11 Intrinsics manual.
+
+
+<P>
+The operation mode may be selected by one of the mode selectors in the bottom
+left corner, by one of the function keys listed earlier in this chapter,
+or by pressing the space bar to cycle through the modes.
+<EM>&#60;Btn1Down&#62;</EM> sends a notify request to the application which
+responds by creating or changing the appropriate object or at least takes
+the first step to do so. Switching to a mode causes the cursor to take
+on a unique shape and also causes the cooresponding
+mode selector button to be drawn with thick lines. You can use either cue
+to see which mode is currently selected.
+
+
+<P>
+Removing objects is possible using <EM>&#60;Key&#62;BackSpace</EM> (or <EM>&#60;Key&#62;Delete</EM>
+on some machines)
+which deletes the object at the cursor location. If more than one object
+is located at the same position, the smallest matching type will be chosen.
+If two or more of the same type are the smallest at the position, then the
+newest one will be deleted.
+You also may change to <EM>remove-mode</EM> and click <EM>&#60;Btn1Down&#62;</EM>
+at the location of the objects which are to be removed. If you "remove"
+the end-point where two lines connect, it will remove the point of
+connection leaving a single line that spans the far end points.
+
+
+<P>
+Rotating works in a similar fashion. Change the mode and press
+<EM>&#60;Btn1Down&#62;</EM> at the object's location. Remember only text,
+elements and arcs can be rotated. (Anything including groups of objects
+may be rotated inside a buffer using the rotate buffer menu option.)
+
+
+<P>
+Insert mode provides the capability of inserting new points into existing
+polygons or lines. The 45 degree line clipping is now enforced when selected.
+Press and hold the shift key while positioning the new point to only clip
+the line segment to the nearer of the two existing points to 45 degrees.
+You can also toggle the 45-degree clipping in the middle of a point
+insertion by pressing the <EM>&#60;Key&#62;.</EM>
+If the shift key is not depressed and the 45 degree line clipping mode
+is on, both new line segments must be on 45 degree angles - greatly
+restricting where the new point may be placed. In some cases this can cause
+confusion as to whether an insertion has been started since the two new
+lines may be forced to lie parallel on top of the original line until the
+pointer is moved far from the end points.
+
+
+<P>
+Removing objects, changing their size or moving them only applies to objects
+that are visible when the command is executed.

+
+
+<P>
+<EM>&#60;Btn1Down&#62;</EM> creates (or deletes) an object depending on the

+
+
+<P>
+<EM>&#60;Key&#62;BackSpace</EM> or <EM>&#60;Key&#62;Delete</EM> removes the visible
+object at the cursor location. When more than one object exists at the
+location, the order of removal is: via, line, text, polygon and
+element. The drawn layer order also affects the search - whatever is
+top - most (except elements) is affected before lower items. Basically
+all this means that what is removed is probably just what you expect.
+If for some reason it isn't, undo and try again.
+Only one object is removed for each keystroke. If two or more
+of the same type match, the newest one is removed.
+
+
+<P>
+Use <EM>&#60;Key&#62;s</EM> and <EM>Shift&#60;Key&#62;s</EM> to change the size (width)

+<P>
+A polygon is drawn by defining all of its segments as a series of
+consecutive line segments. If the first point matches a new one and if
+the number of points is greater than two, then the polygon is closed.
+Since matching up with the first point may be difficult, you may use
+<EM>Shift&#60;Key&#62;p</EM> to close the polygon. The <EM>Shift&#60;Key&#62;p</EM> won't
+work if clipping to 45 degree lines is selected
+and the final segment cannot match this condition.
+I suggest you create simple convex polygons in order to avoid a strong
+negative impact on the performance of the connection scanning routines.
+The <EM>rectangle-mode</EM> is just an easy way to generate rectangular polygons.
+<EM>Polygon-mode</EM> also is selected by <EM>&#60;Key&#62;F6</EM> whereas
+<EM>rectangle-mode</EM> uses <EM>&#60;Key&#62;F4</EM>.
+Pressing a <EM>&#60;Btn1Down&#62;</EM> at two locations creates a rectangle by
+defining two of its corners.
+<EM>&#60;Key&#62;Insert</EM> brings you to <EM>insert-point-mode</EM> which lets you
+add additional points to an already existing polygon.
+Single points may be removed by moving the crosshair to them and selecting
+one of the delete actions <EM>(remove-mode, BackSpace, or Delete</EM>. This only works
+if the remaining polygon will still have three or more corners.
+Pressing <EM>&#60;Key&#62;u</EM> or <EM>&#60;Key&#62;p</EM> while entering a new polygon
+brings you back to the previous corner. Removing a point does not
+force clipping to 45 degree angles (because it's not generally possible).
+Newly created polygons will not connect to pins or vias
+that pierce it unless you create a thermal (using the thermal mode) to make
+the connection. If the edge of a polygon gets too close to a pin or via that
+lies outside of it, a warning will be issued and the pin will be given a
+special color. Increasing the distance between them will remove the warning
+color.

+<EM>&#60;Key&#62;n</EM> changes the name of a via. If you want to create a mounting

+still a via, but it has no copper annulus. If you create such a hole in
+the middle of two polygons on different layers, it will short the layers.
+Theoretically you could arrange for such a hole not to be plated, but a
+metal screw inserted in the hole would still risk shorting the layers.
+A good rule is to realize that holes in the board really are vias between
+the layers and so place them where they won't interfere with connectivity.

+Now that you're familiar with many of the basic commands, it is

+First of all, you have to load data into the paste buffer.
+There are four ways to do this:
+
+<PRE>
+ 1) load the data from a library
+ 2) load the data from a file
+ 3) copy data from an already existing element
+ 4) convert objects in the buffer into an element
+</PRE>

+We don't have any elements on the screen yet nor anything in the
+buffer, so we use number one.

+Select <EM>lsi</EM> from the menu in the library window press
+<EM>&#60;Btn1Down&#62;</EM> twice at the appropriate text-line to get
+the MC68030 CPU.
+The data is loaded and the mode is switched to <EM>pastebuffer-mode</EM>.
+Each notify event now creates one of these beasts. Leave the mode
+by selecting a different one or by <EM>&#60;Key&#62;Escape</EM> which resets
+all modes..
+The crosshair is located at the <EM>mark</EM> position as defined by
+the data file. Rotating the buffer contents is done by selecting
+the <EM>rotate</EM> entry of the <EM>Buffer</EM> menu or by pressing
+<EM>Shift&#60;Key&#62;F3</EM>. The contents of the buffer
+are valid until new data is loaded into it either by a cut-to-buffer
+operation, copy-to-buffer operation or by loading a new data file.
+There are 5 buffers
+available. Switching between them is done by selecting a menu entry or
+by <EM>Shift&#60;Key&#62;1..5</EM>.
+Each of the two board sides has its own buffers.
+
+
+<P>
+The release includes all data files for the circuits that are used
+by the demo layout. The elements in the LED example are not found in the library,
+but you can lift them from the example itself if you want.
+If you have problems with the color of the crosshair, change the resource
+<EM>crosshairColor</EM> setting to a different one.

+Now load a second circuit, the MC68882 FPU for example.
+Create the circuit as explained above. You now have two different unnamed
+elements. Unnamed means that the layout-name of the element
+hasn't been set yet. Selecting <EM>description</EM> from the <EM>Display</EM>
+menu displays the description string of the two circuits which
+are CPU and FPU. The values of the circuits are set to MC68030 and MC68882.
+Each of the names of an element may be changed
+by <EM>&#60;Key&#62;n</EM> at the elements location and editing the old name in
+the bottom input line. Naming pins and vias is similar to elements.
+You can hide the element name so that it won't appear on the board
+silkscreen by pressing <EM>&#60;key&#62;h</EM> with the cursor over the element.
+Doing so again un-hides the element name.
+
+
+<P>
+Entering <KBD>:le</KBD> and selecting an element data file is
+the second way to load circuits.
+
+

+The fourth way to create a new element is to convert a buffer's contents
+into an element. Here's how it's done: Select the Via-tool from the
+<EM>Tool pallette</EM>. Set the grid spacing to something appropriate for
+the element pin spacing. Now create a series of vias where the pins
+go. Create them in pin number order. It is often handy to place a reference
+point (<EM>!Ctrl&#60;Key&#62;m</EM>) in the center of the first pin in order to measure
+the location of the other pins. Next make a solder-side layer the active
+layer from the <EM>active-layer</EM> popup menu. Now draw the outline of
+the element using lines and arcs. When you're done, select everything that
+makes up the element with a box selection (<EM>&#60;Btn3Down&#62; drag,
+&#60;Btn3Up&#62;</EM>). Now select "cut selection to buffer" from the <EM>Buffer</EM>
+menu. Position the cursor over the center of pin 1 and press the left
+button to load the data into the buffer.
+Finally select "convert buffer to element" from the <EM>Buffer</EM> menu.
+You'll only want to create elements this way if they aren't already in the
+library. It's also probably a good idea to do this before starting any of
+the other aspects of a layout, but it isn't necessary.
+
+
+<P>
+To display the pinout of a circuit move to it and press <EM>Shift&#60;Key&#62;d</EM>
+or select <EM>show pinout</EM> from the <EM>Objects</EM> menu. A new window
+pops up and displays the complete pinout of the element. This display can
+be difficult to read if the component has been rotated 90 degrees :-(
+therefore, the new window will show an un-rotated view so the pin names
+are readable.
+<EM>&#60;Key&#62;d</EM> displays the name of one or all pins/pads inside the
+drawing area, this is only for display on-screen, it has no effect on any
+printing of the layout.
+
+
+<P>
+You also may want to change a pin's or pad's current size by pressing
+<EM>&#60;Key&#62;s</EM> to increase or <EM>Shift&#60;Key&#62;s</EM> to decrease it. While
+this is possible, it is not recommended since care was probably taken
+to define the element structure in the first place. You can also change the thickness
+of the element's silkscreen outline with the same keys. You can
+change whether a pin or SMD pad is rounded or square with the <EM>&#60;Key&#62;q</EM>.
+SMD pads should usually have squared ends. Finally, you can change whether
+the non-square pins are round or octagonal with the <EM>!Ctrl&#60;Key&#62;o</EM>.

+SMD elements and silkscreen objects are drawn in the "invisible object"

+After completing parts of your layout you may want to check if all drawn
+connections match the ones you have in mind. This is probably best done
+in conjunction with a net-list file: see section <A HREF="pcb.html#SEC34">Rats Nest</A>.
+The following examples give more rudimentary ways to examine
+the connections.
+
+<PRE>
+ 1) create at least two elements and name them
+ 2) create some connections between their pins
+ 3) optionally add some vias and connections to them
+</PRE>
+
+<P>
+Now select <EM>lookup connection</EM> from the <EM>Connections</EM> menu,
+move the cursor to a pin or via and press any mouse button. <CODE>Pcb</CODE>
+will look for all other pins and/or vias connected to the one you have
+selected and display the objects in a different color.
+Now try some of the reset options available from the same menu.
+
+
+<P>
+There also is a way to scan all connections of one element. Select
+<EM>a single element</EM> from the menu and press any button at the
+element's location. All connections of this element will be saved
+to the specified file.
+Either the layout name of the element or its canonical name is used to
+identify pins depending on the one which is displayed on the screen
+(may be changed by <EM>Display</EM> menu).
+
+
+<P>
+An automatic scan of all elements is initiated by choosing
+<EM>all elements</EM>. It behaves in a similar fashion to scanning a single
+element except the resource <EM>resetAfterElement</EM>
+is used to determine if connections should be reset before a new element is
+scanned. Doing so will produce very long lists because the power lines are
+rescanned for every element. By default the resource is set to <EM>false</EM>
+for this reason.
+

+<H2><A NAME="SEC34" HREF="pcb_toc.html#TOC34">Rats Nest</A></H2>
+<P>
+If you have a netlist that corresponds to the layout you are working on, you
+can use the rats-nest feature to add rat-lines to the layout.
+First you will need to load a netlist file (see <EM>:rn</EM>,
+section <A HREF="pcb.html#SEC36">User Commands</A>).
+<EM>&#60;Key&#62;w</EM> adds rat-lines on the active layer using the current
+line thickness shown in the status line (usually you'll want them to be thin lines).
+Only those rat-lines that fill in missing connectivity (since you have
+probably routed some connections already) are added.
+If the layout is already completely wired, nothing will be added, and you will
+get a message that the wiring is complete.
+
+
+<P>
+Rat-lines are lines having the special property that they only connect to pins and
+pads at their end points. Rat-lines are drawn on the screen with a stippled pattern
+to make them easier to identify since they have special behavior and cannot
+remain in a completed layout.
+Rat-lines are added in the minimum length straight-line tree pattern
+(always ending on pins or pads) that satisfies the missing connectivity in the circuit.
+Used in connection with moves and rotates of the elements, they are extremely useful for
+deciding where to place elements on the board. The rat-lines will always automatically
+rubberband to the elements whether or not the rubberband mode is on. The only way for
+you to move them is by moving the parts they connect to.
+This is because it is never desireable to have the rat-lines disconnected from
+their element pins. Rat-lines will normally criss-cross
+all over which gives rise to the name "rats nest" describing a layout connected with
+them. If a SMD pad is unreachable on the active layer, a warning will be issued
+about it and the rat-line to that pad will not be generated.
+
+
+<P>
+A common way to use rats nests is to place some
+elements on the board, add the rat-lines, and then use a series of moves/rotates of the
+elements until the rats nest appears to have minimum tangling. You may want to iterate this step
+several times. Don't worry if the layout looks messy - as long as you can get a sense for whether
+the criss-crossing is better or worse as you move things, you're fine.
+After moving some elements arround, you may want to optimize the rats nest <EM>&#60;Key&#62;o</EM>
+so that the lines are drawn between the closest points (this can change once you've moved components).
+Adding rat-lines only to selected pads/pins (<EM>Shift&#60;Key&#62;w</EM>)
+is often useful to layout a circuit a little bit at a time.
+Sometimes you'll want to delete all the rat-lines (<EM>&#60;Key&#62;e</EM>) or
+selected rat-lines (<EM>Shift&#60;Key&#62;e</EM>) in order to reduce confusion.
+With a little practice you'll be able to achieve a near optimal component placement with
+the use of a rats nest.
+
+
+<P>
+Rat-lines are not only used for assisting your element placement, they can also help
+you to route traces on the board.
+Use the <EM>&#60;Key&#62;m</EM> to convert a rat-line under the cursor into
+a normal line on the active layer.
+Inserting a point into a rat-line will also cause the two new lines to be normal lines
+on the board.
+Another way that you can use rat-lines is to
+use the <EM>&#60;Key&#62;f</EM> with the cursor over a pad or pin. All of the pins and
+pads and rat-lines belonging to that net will be highlighted. This is a helpful way to
+distinguish one net from the rest of the rats nest. You can then route those tracks,
+turn off the highlighting (<EM>Shift&#60;Key&#62;f</EM>) and repeat the process. This will work even
+if the layer that the rat-lines reside on is made invisible - so only the pins and pads
+are highlighted.
+Be sure to erase the rat-lines (<EM>&#60;Key&#62;e</EM> erases them all) once you've
+duplicated their connectivity by adding your own lines.
+When in doubt, the <EM>&#60;Key&#62;o</EM> will delete only those
+rat-lines that are no longer needed.
+
+
+<P>
+If connections exist on the board that are not listed in the netlist when
+<EM>&#60;Key&#62;w</EM> is pressed, warning messages are issued and the affected pins and
+pads are drawn in a special <EM>warnColor</EM> until the next <EM>Notify()</EM> event.
+If the entire layout agrees completely with the netlist, a message informs you that
+the layout is complete and no rat-lines will be added (since none are needed).
+If the layout is complete, but still has rat-lines then you will be warned
+that rat-lines remain. If you get no message at all it's probably because some
+elements listed in the net list can't be found and where reported in an earlier
+message.
+There shouldn't be any rat-lines left in a completed layout, only normal lines.
+
+
+<P>
+The <EM>Shift&#60;Key&#62;w</EM> is used to add rat-lines to only those missing connections among
+the selected pins and pads. This can be used to add rat-lines in an incremental
+manner, or to force a rat-line to route between two points that are not the
+closest points within the net. Often it is best to add the rats nest in an incremental fashion, laying
+out a sub-section of the board before going further. This is easy to accomplish since
+new rat-lines are never added where routed connectivity already makes the necessary
+connections.

+<H2><A NAME="SEC35" HREF="pcb_toc.html#TOC35">Design Rule Checking</A></H2>
+<P>
+After you've finished laying out a board, you may want to check
+to be certain that none of your interconnections are too closely
+spaced or too tenuously touching to be reliably fabricated. The design
+rule checking (DRC) function does this for you. Use the command ":DRC()" (without
+the quotes of course) to invoke the checker. If there are no problem areas,
+you'll get a message to that effect. If any problem is encountered, you will get
+a message about it and the affected traces will be highlighted. One part of the
+tracks of concern will be selected, while the other parts of concern will have the
+"FindConnection" highlighting. The screen will automatically be centered in the
+middle of the object having the "FindConnection" (Green) highlighting. The middle of
+the object is also the coordinates reported to be "near" the problem. The actual trouble
+region will be somewhere on the boundary of this object. If the two parts are
+from different nets then there is some place where they approach each
+other closer than the minimum rule. If the parts are from the same net, then
+there is place where they are only barely connected. Find that place and connect
+them better.
+
+
+<P>
+After a DRC error is found and corrected you must run the DRC again because
+the search for errors is halted as soon as the first problem is found. Unless you've
+been extremely careless there should be no more than a few design rule errors
+in your layout. The DRC checker does not check for minimum spacing rules to
+copper text, so always be very careful when adding copper text to a layout.
+The rules for the DRC are specified in the application resource file. The minimum
+spacing value (in mils) is given by the <EM>Settings.Bloat</EM> value. The default
+is 7 mils. The minimum touching overlap (in mils) is given by the
+<EM>Settings.Shrink</EM> value. This value defaults to 5 mils. Check with your
+fabrication process people to determine the values that are right for you.
+
+
+<P>
+If you want to turn off the highlighting produced by the DRC, perform an
+undo (assuming no other changes have been made). To restore the highlighting,
+use redo. The redo will restore the highlighting quickly without re-running
+the DRC checker.

+only work provided the via's diameter is sufficiently large to accomodate a 32 mil hole).
+Another example might be to set the grid to 1 mil by typing "<EM>:SetValue(Grid, 1)</EM>".
+Note that some actions use the current cursor location, so be sure to place the cursor
+where you want before entering the command. This is one of my favorite new
+features in 1.5 and can be a powerful tool. Study the section <A HREF="pcb.html#SEC42">Actions</A> section to

+Adds rat-lines to the layout using the loaded netlist file (see the <EM>:rn</EM>,

+Only missing connectivity is added by the

+Rat lines are drawn on the screen with a stippled pattern
+to make them easier to identify since they cannot appear in a completed layout.
+The rat-lines are added in the minimum length straight-line tree pattern
+(always ending on pins or pads) that satisfies the missing connectivity in the circuit.
+If a SMD pad is unreachable on the active layer, a warning will be issued
+about it and the rat-line to that pad will not be generated.

+AllRats are being added, warning messages will be issued and the affected pins and
+pads will be drawn in a special <EM>warnColor</EM> until the next <EM>Notify()</EM> event.
+If the entire layout agrees completely with the net-list a message informs you that

+This action routines handles some output related settings. It is
+used to center the display around the cursor location and to redraw the
+output area optionally after clearing the window.
+Centering is done with respect to the <EM>grid</EM> setting. Displaying the
+grid itself may be switched on and off by <EM>Grid</EM> but only if
+the distance between two pixels exceeds 1_DISTANCE pixels.
+<CODE>Pcb</CODE> is able to handle several labels of an element. One of them
+is a description of the functionality (eg resistor), the second should be
+a unique identifier (R1) whereas the last one is a value (100k).
+The <EM>Display()</EM> action selects which of the names is displayed.
+It also controls which name will be affected by the <EM>ChangeName</EM> command.
+If <EM>ToggleGrid</EM> is passed, <CODE>Pcb</CODE> changes between relative
+('rel' in the statusline) and absolute grid (an 'abs' in the statusline).
+Relative grid means the pointer position when the command is issued is
+used as the grid origin; while (0,0) is used in the absolute grid case.
+Passing <EM>Pinout</EM> displays the pinout of the element at the current
+cursor location whereas <EM>PinOrPadName</EM> toggles displaying of the
+pins or pads name under the cursor. If none of them matches but the cursor
+is inside of an element, the flags is toggled for all of its pins and pads.

+Switches to a new mode of operation. The active mode is displayed by a thick
+line around the matching mode selector button.
+Most of the functionality of <CODE>Pcb</CODE> is implemented by selecting a mode
+and calling <EM>Mode(Notify)</EM>. The arguments <EM>Line</EM>, <EM>Polygon</EM>,
+<EM>Rectangle</EM>, <EM>Text</EM> and <EM>Via</EM> are used to create the
+appropriate object whenever <EM>Mode(Notify)</EM> is called. Some of them,
+such as <EM>Polygon</EM>, need more than one call for one object to be created.
+<EM>InsertPoint</EM> adds points to existing polygons or lines.
+<EM>Save</EM> and <EM>Restore</EM> are used to temporarily save the mode, switch
+to another one, call <EM>Mode(Notify)</EM> and restore the saved one. Have
+a look at the application resource file for examples.
+<EM>Copy</EM> and <EM>Move</EM> modes are used to change an object's location and,
+optionally, to create a new one. The first call of <EM>Mode(Notify)</EM> attaches
+the object at the pointer location to the crosshair whereas the second
+one drops it to the layout. The <EM>rubberband</EM> version of move performs the
+move while overriding the current rubberband mode.
+Passing <EM>PasteBuffer</EM> attaches the contents of the currently selected
+buffer to the crosshair. Each call to <EM>Mode(Notify)</EM> pastes this contents
+to the layout. <EM>Mode(Cycle)</EM> cycles through the modes available in the
+mode-button pallete.

+All files used by <CODE>Pcb</CODE> are read from the standard output of a command

+makes it possible to use any editor to change the contents of a layout file.
+It is the only way for element or font description files to be created.
+To do so you'll need to study the example files <TT>`example/*'</TT> and

+Element files are used to describe one component which then may be used
+several times within one or more layouts. You will normally split the
+file into two parts, one for the pinout and one for the package description.
+Using <CODE>m4</CODE> allows you to define pin names as macros in one file and
+include a package description file which evaluates the macros. See
+the resource <EM>elementCommand</EM> for more information. The pins (and pads)
+must appear in squential order in the element file (new in 1.5) so that
+pin 1 must be the first PIN(...) in the file.
+
+
+<P>
+Doing things this way makes it possible to use one package file for several
+different circuits. See the sample files <TT>`dil*'</TT>.

+<P>
+This section provides an overview about the existing <CODE>m4</CODE> definitions
+of the elements. There are basically two different types of files. One
+to define element specific data like the pinout, package and so on, the
+other to define the values. For example the static RAM circuits 43256 and
+62256 are very similar. They therefore share a common definition in the
+macro file but are defined with two different value labels.
+
+
+<P>
+The macro file entry:
+
+<PRE>
+define(`Description_43256_dil', `SRAM 32Kx8')
+define(`Param1_43256_dil', 28)
+define(`Param2_43256_dil', 600)
+define(`PinList_43256_dil', ``pin1', `pin2', ...')
+</PRE>
+
+<P>
+And the list file:
+
+<PRE>
+43256_dil:N:43256:62256
+</PRE>
+
+<P>
+The macro must define a description, the pin list and up to two additional
+parameters that are passed to the package definitions. The first one is
+the number of pins whereas the second one defines for example the width
+of a package.
+
+
+<P>
+It is very important to select a unique identifier for each macro. In
+the example this would be <EM>43256_dil</EM> which is also the templates name.
+It is required by some low-level macros that
+<EM>Description_, Param1_, Param2_</EM> and <EM>PinList_</EM> are prepended.
+
+
+<P>
+The list file uses a syntax:
+
+<PRE>
+template:package:value[:more values]
+</PRE>
+
+<P>
+This means that the shown example will create two element entries with the
+sam package and pinout but with different names.
+
+
+<P>
+A number of packages are defined in <TT>`common.m4'</TT>. Included are:
+
+
+
+<PRE>
+DIL packages with suffix D, DW, J, JD, JG, N, NT, P
+PLCC
+TO3
+generic connectors
+DIN 41.612 connectors
+zick-zack (SD suffix)
+15 pin multiwatt
+</PRE>
+
+<P>
+If you are going to start your own library please take care about <CODE>m4</CODE>
+functions. Be aware of quoting and so on and, most important check your
+additional entry by calling the macro:
+
+
+
+<PRE>
+CreateObject(`template', `value', `package suffix')
+</PRE>
+
+<P>
+If quoting is incorrect an endless loop may occur (broken by a out-of-memory
+message).
+
+
+<P>
+The scripts in the <TT>`lib'</TT> directory handle the creation of libraries
+as well as of their contents files. Querying is also supported.
+
+
+<P>
+I know quite well that this description of the library implementation is
+not what some out there expect. But in my opinion it's much more useful to
+look at the comments and follow the macros step by step.

+Now run <CODE>xmkmf -a</CODE> which creates the <TT>`Makefiles'</TT> and runs

+You have to be root to install the package or at least a user with

+<CODE>make install</CODE> and <CODE>make install.man</CODE> install the program,

+There are some known problems. Most of them are related to

+third party applications such as <CODE>X</CODE> servers. To make this list more
+complete please mail your problems and, if available, solutions to the author.
+The mail address may be found at the beginning of this chapter.
+In any case, read section <A HREF="pcb.html#SEC64">Problems related to X11</A>.
+
+
+<P>
+By the way, you <CODE>MUST HAVE AN ANSI COMPILER</CODE> to make <CODE>Pcb</CODE> work.
+
+
+<P>
+If the shell script <CODE>create_sed_script.sh</CODE> fails with an error
+of <CODE>awk</CODE> check your system for <CODE>nawk</CODE> or get the <CODE>GNU gawk</CODE>.
+See the script for details.
+
+
+<P>
+Another source of problems are older versions of <CODE>flex</CODE> and <CODE>bison</CODE>.
+<CODE>Pcb</CODE> definitely works with <CODE>flex-2.4.7</CODE> and <CODE>bison-1.22</CODE> or
+later. The problems will result in a <EM>syntax error</EM> while parsing files.
+You will have to add <EM>-lfl</EM> to the SYS_LIBRARIES identifier in

+or, better, install a complete <CODE>X11R5</CODE> release. Hewlett-Packard doesn't
+support the Athena Widgets. So the header files and libraries are missing

+They also do not ship the <CODE>ANSI</CODE> compiler with the normal operating

+
+History
+*******
+
+ `Pcb' is a handy tool for laying out printed circuit boards. It was
+first written for an Atari ST in 1990 and ported to `UNIX' and `X11' in
+1994. I never had the intention to create another professional layout
+system, but to write a tool which supports people like you who do some
+home-developing of hardware. For this reason it has no auto-router nor
+auto-placement code.
+
+ The second release 1.2 included menus for the first time. This made
+`PCB' easier to use and thus a more important tool.
+
+ Release 1.3 introduced undo for highly-destructive commands, more
+straightforward action handling and scalable fonts. Layer-groups were
+introduced to group signal-layers together.
+
+ Release 1.4 provided support for add-on device drivers. Two layers
+(the solder and the component side) were added to support SMD elements.
+The handling of libraries was also improved in 1.4.1. Support for
+additional devices like GERBER plotters started in 1.4.4. The undo
+feature was expanded and the redo-feature added in 1.4.5.
+
+ Release 1.5 provides support for rats-nest generation from simple net
+lists. It also allows for automatic clearances around pins that pierce
+a polygon. A variety of other enhancments including a Gerber RS274X
+driver and NC drill file generation have also been added. harry eaton
+(haceaton@aplcomm.jhuapl.edu) was responsible for most of the changes
+found in this release.
+
+ Release 1.6 provides automatic screen updates of changed regions.
+This should elliminate most of the need for the redraw (r) key. Also
+some changes to what order items under the cursor are selected were
+made for better consistancy - it is no longer possible to accidentally
+move a line or line point that is completely obscured by a polygon
+laying over top of it. Larger objects on the upper most layers can be
+selected ahead of smaller objects on lower layers. These changes make
+operations more intuitive. A new mode of line creation was added that
+creates two line on 45 degree angles with a single click. The actual
+outline of the prospective line(s) are now shown during line creation.
+An arc creation mode was added. Drawn arcs are quarter circles and can
+be useful for high frequency controlled impedance lines. (You can have
+eighth circle arc if the source is compiled with -DARC45, but be aware
+that the ends of such arcs can never intersect a grid point). Two new
+flags for pins and vias were created - one indicates that the pin or
+via is purely a drill hole and has no copper annulus. You can only
+toggle this flag for vias - for elements, it must be an integral part
+of the element definition. The other flag controls whether the pad
+will be round or octagonal. There is also now a feature for converting
+the contents of a buffer into an element. Vias become the pins (or
+mounting holes), lines and arcs on the solder layer become silkscreen,
+and lines on the component layer become the pads. Action commands
+entered via the colon command entry are no longer proceeded with "a ",
+just type the command directly. Several bugs have also been fixed. New
+ones were probably introduced since extensive changes were made. harry
+eaton was responsible for these changes.
+
+ Release 1.6.1 adds the ability to make groups of action commands
+bound to a single X11 event to be undone by a single undo. Also a
+simple design rule checker was added - it checks for minimum spacing
+and overlap rules. Plus many fixes for bugs introduced with the many
+changes of 1.6 harry is responsible for these changes too.

+Introduction
+************
+
+ Each layout consists of several, mostly independent, objects. This
+chapter gives an overview of the object types and their relationship to
+each other. For a complete description of how to use `Pcb', refer to
+*Note Getting Started::. The layout is generated on-screen on a grid
+that has its origin in the upper left corner of the screen. The x
+coordinate increases to the right, y increases down to the bottom. All
+distances and sizes in `Pcb' are measured in mils (0.001 inch). One
+unit on the display grid is one mil in distance on the board. The
+sections in this chapter are sorted by the order of appearance of the
+objects within a layout file.
+
+* Menu:
+
+* Symbol Objects:: Information about fonts and symbols.
+* Via Objects:: Vias and pins connect layers.
+* Element Objects:: Element, the basic type of circuits.
+* Layer Objects:: A `container' for lines, text...
+* Line Objects::
+* Arc Objects::
+* Polygon Objects::
+* Text Objects:: Objects to add symbols to your board.
+
+
+File: pcb.info, Node: Symbol Objects, Next: Via Objects, Up: Intro
+
+Symbols
+=======
+
+ The top object is the layout itself. It uses a set of symbols that
+resides at the first logical level. Each symbol is uniquely identified
+by a seven bit `ASCII' code. All layout objects share the same set of
+symbols. These symbols are used to form text objects on the silkscreen
+and copper layers. Undefined symbols are drawn as filled rectangles.
+
+ Every font file is preprocessed by a user-defined command when it is
+loaded. For details see `fontCommand', *Note Resources::.
+
+
+File: pcb.info, Node: Via Objects, Next: Element Objects, Prev: Symbol Objects, Up: Intro
+
+Vias
+====
+
+ Vias are identical to the pins used by elements except that they can
+be added or removed individually. The purpose of vias is to provide
+connections between different layers. Don't use vias for adding
+elements to the layout, even if that seems easier than creating a new
+element. Vias are useful for defining arbitrary drill points such as
+those used for mounting a board. You can assign a name to a via even
+though you probably won't ever want to. Vias reside at the first
+logical level; therefore, each via exists on all layers. (*i.e.* blind
+vias are not supported)
+
+
+File: pcb.info, Node: Element Objects, Next: Layer Objects, Prev: Via Objects, Up: Intro
+
+Elements
+========
+
+ Elements represent the components on a board. Elements are loaded
+from `ASCII' coded files in a similar manner to the layout file itself.
+They are composed of lines and arcs on the silk-screen layer (used to
+define the package outline) , pins (or pads for SMD) and three labels
+that define the description, the element's layout-name (which also
+appears on the silk- screen layer) and its value. Element pins are
+contained on the first logical level and so reside on all layers. A
+mark is used to position the element with respect to the cursor
+cross-hair during pasting. SMD elements use pads instead of pins.
+Pads are handled similarly to lines on a layer but they must be oriented
+either vertically or horizontally. Pads can have either rounded or
+square ends. All parts of an element are treated as one unit. It is
+not possible to delete a single pin or break an element into pieces on
+the layout. You can resize separate pieces of an element, but doing so
+is usually a bad idea.
+
+ Elements are supported by several special layers: *silk*,
+*pins/pads* and *far-side*. The *silk* layer shows the package outline
+and also holds legend text and element names. The *pins/pads* layer is
+used to toggle whether the element's pins and pads are displayed. The
+*far-side* layer controls visibility of objects (silkscreen and pads)
+that are on the far (*i.e.* not currently viewed) side of the board.
+
+ Every element file is preprocessed by a user-defined command when
+the file is read. For details see `elementCommand', *Note Resources::.
+`m4', the default value of `elementCommand', allows you to create
+libraries for package definitions that are shared by all elements. The
+element libraries distributed with `Pcb' expect `m4' or an equivalent
+to be the *elementCommand*.
+
+ `Pcb' can create a list of all connections from one (or all)
+elements to the others or a list of unconnected pins. It can also
+verify the layout connections against a netlist file. The element's
+`layout-name' is the name used to identify an element in a netlist file.
+The pin numbering for an element is defined by unique strings assigned
+to each pin. In addition to the "pin number" string, each pin has a
+"name" which describes its function. Previously element pin number was
+established by the order of appearance of the pin definitions in the
+layout or element file. Since the "number" strings for each pin are a
+new feature, if they are absent then the numbering is again established
+by the order of pin appearance in the file. In other words, the first
+pin appearing in the file is pin one, the next pin is pin two and so on.
+Usually the names assigned to pins are simply numbers, but they don't
+have to be. It is only necessary that the "number" string for the pin
+matches exactly the "number" string in the netlist file. Be aware that
+a few of the library parts may still be incorrectly implemented
+regarding pin-numbering. All of the DIL (Dual- Inline-Pins) parts are
+correct and most of the others are too, but you should verify the pin
+numbering of any non-DIL part (use the *Report Menu* to see what `Pcb'
+thinks a pin's number is) before using the rats nest feature with a
+library part. Hopefully sometime soon someone will volunteer to
+cross-check all of the element libraries and make fixes available as
+necessary. `Pcb' can also check a layout to see that it meets minimum
+spacing and overlap rules.
+
+ You can make your own quick-and-dirty element definitions
+graphically now. Simply draw vias for the pins and lines and arcs on a
+solder layer for the silkscreen outline. You should name each via with
+the pin number. If you want to create a SMD device, draw lines for the
+pads on a component side layer (You must draw these in pin number order
+since lines can't be named). They must be either horizontal or vertical
+or they will not be recognized as pads. Once you are happy with the
+geometry, select everything that is to become part of the element, then
+choose "cut to buffer" from the menu. Now select "convert buffer to
+element" from the menu. Viola'! Afterwards you can make pin one
+square (or pads) if you like, and give the element its various names.
+Note that the element mark corresponds to the cut position when
+everything was put into the buffer. If the vias are not named, then the
+pin numbering will correspond to the order in which the vias were
+placed.
+
+

+
+Layers
+======
+
+ Every layout consists of several layers that can be used
+independently or treated as a group. Layer groups can be used to
+logically separate (and color-code) different traces (*e.g.* power and
+signal); however, all layers within a group reside on the same physical
+copper layer of a board, so using different layers within the same
+group won't provide electrical separation where they touch or overlap.
+For details, see `layerGroups', *Note Resources::. Each layer is drawn
+in a color defined in the resource file (for details see `layerColor',
+*Note Resources::) and identified by a name that you can change.
+Layers are really just containers for line, polygon, and text objects.
+The component and solder layers contain SMD elements as well, but the
+file structure doesn't reflect that fact directly. Each layer group
+represents a physical layer on the printed circuit board. If you want
+to make a four layer board, you'll need to have four layer groups.
+Connections between layer groups are established only through element
+pins and vias. The relationship between a specific layer and the board
+itself is configureable from the `Edit layer groups' option in the
+`Objects' menu. The layer groups corresponding to the physical layers
+*component-side* and *solder-side* are always defined, and you must map
+at least one logical layer to each. Of course, you are not obligated
+to put tracks on either of them. SMD-elements always reside on either
+the component-side or the solder-side layer group. You can swap which
+side of the board you are viewing by pressing *<Key>Tab*. You can
+decide which layer group will be the solder side and which will be the
+component side. The layers groups just have a name or number
+associated with them - where they are sandwiched in the board is left
+to the manufacturing processes.
+
+
+File: pcb.info, Node: Line Objects, Next: Arc Objects, Prev: Layer Objects, Up: Intro
+
+Lines
+=====
+
+ Lines are used to draw tracks on the pc board. When in the line
+mode, each *<Btn1>* press establishes one end of a line. Once the
+second point is defined, the line is drawn and a new line started where
+the first one ended. You can abondon the new starting point in favor
+of another by pressing *Ctrl<Btn1>*. The undo function (*<Key>u*) will
+take you back point by point if you use it while in the line mode. New
+lines can be restricted to 45 degree angles if desired. You can toggle
+this restriction on and off while creating lines by pressing *<Key>.*
+(that is the *period* key). If the 45 degree restriction is turned on,
+then the *<Key>/* can be used to cylce through three different modes of
+45 degree line creation. One mode just creates a single line forced to
+the nearest 45 degree vector. The next mode creates two lines from the
+start to end points such that the first line leaves the start point at
+a 90 degree vector, and the second line enters the end point on a 45
+degree vector. The next mode creates two lines such that the first line
+leaves the start point on a 45 degree vector and arrives at the end
+point on a 90 degree vector. You can temporarily swap between the last
+two modes by holding the shift key down. It is simple to edit a line
+type object by breaking it into pieces (insert point mode), moving an
+end point (or the whole line) (*<Btn2Down><drag><Btn2Up>*), or changing
+the layer it resides on (*<Key>m* moves the line under the pointer to
+the active layer). In the case when two line segments meet at exactly
+the same point you can delete the intermediate point, otherwise the
+delete mode removes an entire line. Feel free to experiment since
+`Pcb' will allow you to undo anything that materially affects your work.
+If you switch active layers in the midst of placing lines a via will
+automatically be placed, when necessary, in order to continue the
+connection.
+
+
+File: pcb.info, Node: Arc Objects, Next: Polygon Objects, Prev: Line Objects, Up: Into
+
+Arcs
+====
+
+ With version 1.6 it is possible to draw copper arcs. The arcs are
+restricted to be quarter circles. This means they always bend a right
+angle. They are very similar to lines otherwise. They are created on
+the current layer and have the same thickness that new lines will have.
+The various clicks for creating lines work pretty much the same way
+for creating arcs. The start point for the arc is at the first *<Btn1>*
+position. In order to make the arc curve in the direction desired,
+drag the mouse along the tangent line from the starting position
+towards the end position. If the grid is too coarse, it may not be
+possible to distinguish whether you've moved over then up, or up then
+over, so if you can't seem to make the arc go the direction you want,
+you should decrease the grid spacing. Alternatively you could drawn
+the wrong arc, then rotate and move it where you want. Like the line
+tool, after an arc is drawn a new starting point is established at the
+end point. Whenever a start point is established by either the line or
+arc tools it will be retained if you switch directly between the tools
+(e.g. *<Key>F2* for Lines, *<Key>F8* for Arcs. Of course connection
+searches, undo and all the other features you'd expect work with arcs
+now.
+
+
+File: pcb.info, Node: Polygon Objects, Next: Text Objects, Prev: Arc Objects, Up: Intro
+
+Polygons
+========
+
+ Sometimes it's useful to fill large areas with solid copper. The
+way to do this is with polygons. Polygons can be created in either the
+polygon mode or the rectangle mode. In the polygon mode, you'll have
+to define each corner of the polygon with a mouse click (*<Btn1>*).
+When the last point is clicked exactly on top of the starting point,
+the polygon is finished. Since this can be hard to do, the
+*Shift<Key>p* will enter the final point for you, closing the polygon.
+If the 45 degree angle restriction is turned on and you try to close
+the polygon when it is not possible, you'll get a warning instead. If
+you haven't finished entering a polygon, but want to undo one (or more)
+of the points that you've already defined, use the undo command
+(*<Key>u*). With the rectangle tool, defining the two opposite corners
+is sufficient, but of course the resulting polygon is a rectangle.
+Like lines, a polygon can by edited by deleting, inserting and moving
+the points that define it. `Pcb' is capable of handling complex
+polygons, but using a number of simpler ones improves performance of
+the connection tracing code.
+
+ A new feature in version 1.5 of `Pcb' automatically creates clearance
+regions around pins and vias that pierce a polygon. This means that they
+aren't electrically connected to the polygon unless you add "thermals"
+to cross the clearance region. Thermals can be added and removed by
+selecting the thermal mode and clicking *<Btn1>* on the pin or via.
+Remember that this only creates connections to the polygon on the
+active layer. The great advantage to this new polygon behavior is that
+simple or complex ground and/or power planes can be easily made with
+polygons and seen on the screen. If you don't want this auto-clearance
+behavior, or you load a layout created by an earlier version of `Pcb',
+the old behavior (shorts to all piercing pins and vias) is available.
+A `ChangeSize' operation (*<Key>s*) toggles a polygon between the new
+and old polygon/pin behavior.
+
+
+File: pcb.info, Node: Text Objects, Prev: Polygon Objects, Up: Intro
+
+Text
+====
+
+ Text objects should be used to label a layout or to put additional
+information on the board, but not to identify elements because elements
+have their own labels. Text is always horizontal when first created,
+but the rotate mode can align it along 0, 90, 180 and 270 degree angles.
+Text can be moved from any layer to the silk-screen layer with a
+command in the `selection menu'. Text that is moved to the silk-screen
+layer will appear on the solder-side silk-screen if it originating on a
+solder-side layer. Otherwise moving it to the silk-screen layer will
+put it on the component-side silk-screen. To move text back to a
+copper layer from the silk-screen, use the `MoveToCurrentLayer'
+(*<Key>m*) command. Text on the far side of the board will
+automatically appear mirror-imaged.
+
+ TEXT OBJECTS ON A COPPER LAYER CREATE COPPER LINES BUT THEY ARE NOT
+SCANNED FOR CONNECTIONS OR TESTED FOR CREATING SHORTS VS. THE NETLIST.
+NEITHER ARE TEXT OBJECTS TESTED AGAINST ANY DESIGN RULES.

+
+Getting Started
+***************
+
+ The goal of this chapter is to give you enough information to learn
+how `Pcb' works and how to develop your layouts to make the best use of
+`Pcb''s features. All event translations (*i.e.* the buttons and keys
+you press) refer to the default application resource file shipped with
+`Pcb'. There is probably no need to change them unless your window
+manager uses some of the button events itself; however, if you *want*
+to customize the behavior of `Pcb' then changing the resource file is
+usually the best way to do it.
+
+ Get yourself a printout of this chapter and *User Commands*, if you
+haven't already done so, and follow the examples. An example layout
+may be found in `example/68HC11'. An example illustrating some version
+1.5 features is found in `example/LED' along with its corresponding
+netlist file `example/LED.NET'.
+
+ Start `Pcb' (the actual command will use all lower-case letters)
+without any additional options. If you get the error message:
+
+ can't find default font-symbol-file 'default_font'
+
+ then the font searchpath or filename in the application resource
+ file is wrong. Be sure that your `m4' program supports searchpaths.
+If not, get `GNU m4'. For other messages, see *Note problems::.
+Another quick-start is provided by `pcbtest.sh' in the `src' directory.

+The Application Window
+======================
+
+ The main window consists of five areas: the menu at the top, the
+control panel in the upper left corner, the mode buttons located below
+the control panel, the drawing area to the right of these, and the
+status line at the bottom of the window.
+
+* Menu:
+
+* Status-line and Input-field:: What is the program configuration.
+* Control Panel:: Switch layers on/off; change current one.
+* Mode Selectors:: Select an operation mode.
+* Drawing Area:: Where the layout is drawn.
+* Menu::
+
+
+File: pcb.info, Node: Status-line and Input-field, Next: Control Panel, Up: Application Window
+
+The Status-line and Input-field
+-------------------------------
+
+ The status-line is located at the bottom edge of the main window.
+During normal operation the status information is visible there. When
+a selected menu operation requires an additional button click, the
+status-line is replaced by a message telling you to position the cursor
+and click. When a text input is required, the status-line is replaced
+by the Input-field which has a prompt for the typed input.
+
+ The status-line shows, from left to right, the side of the board
+that you are viewing (*<Key>Tab* changes this), if an absolute (abs) or
+relative (rel) grid is used, if new lines are restricted to 45 degrees,
+which type of 45 degree line mode is active, whether rubberband move and
+rotate mode is on (R), the current grid values, and the zoom factor.
+This information is followed by the line-width, via-size and drilling
+hole in mil, text scaling, the active buffer number and the name of the
+layout. An asterisk appearing at the left edge indicates the layout has
+been modified since the last save. Note that the name of the layout is
+not the same thing as the filename of the layout.
+
+ The input-field pops up (temporarily replacing the status-line)
+whenever user input is required. Two keys are bound to the input field:
+*<Key>Escape* aborts the input, *<Key>Return* finishes it.
+
+ The present cursor position is displayed in the upper right corner
+of the window. Normally this position is an absolute coordinate, but
+with version 1.5 of `Pcb' you can anchor a marker at the current cursor
+location by pressing *Ctrl<Key>m* then the display will read both the
+absolute cursor position as well as the difference between it and the
+marker. Pressing *Ctrl<Key>m* again turns the marker off.

+
+The Control Panel
+-----------------
+
+ The control panel, located at the left side of the window, is used
+to turn on and off the display of layer groups and to select the active
+drawing layer. If a layer hasn't been named, the label "*(unknown)*"
+is used as the defualt.
+
+ The upper control box is used to switch layers on and off. Click
+*<Btn1Down>* on one or more of them. Each click toggles the setting.
+The currently active layer can't be switched off. The layout is
+refreshed when the pointer reenters the drawing area. This prevents
+excessive redrawing when the visibility of several layers is changed.
+When the layers are grouped, clicking on these fields will toggle the
+visibility of all layers in the same group. This is a good idea because
+layers in the same group reside on the same physical layer of the
+actual board. Use the `Edit layer groups' option in the `Objects' menu
+to change the layer groupings. Grouping layers is only useful for
+helping you to color-code signals in your layout. Note that grouping
+layers actually reduces the number of different physical layers
+available for your board, thus to make an eight layer board, you cannot
+group any layers.
+
+ *far side* turns on and off the visibility of elements (including
+SMD pads) on the opposite board side, as well as silk screening on that
+side. It does not automatically hide the x-ray view of the other copper
+layers, these must be turned off separately if desired. Use the *tab*
+key to view the entire board from the other side. To see a view of
+what the back side of the board will actually look like, make the
+solder layer the active layer then press *tab* until the status line
+says "solder" on the right, then turn off the visibility of all other
+layers except pins/pads, vias, and silk.
+
+ The lower control menu, named *active*, is used to change the active
+drawing layer. *<Btn1Down>* pops up a menu to select a one. Each entry
+is labeled with the layer's name and drawn in its color. The new
+drawing layer is automatically made visible. Try changing the active
+layer's name to *ABC* by selecting `set name of layer' from the `File'
+menu. Changing the active layer also is available with *<Key>1..8*.
+
+
+File: pcb.info, Node: Mode Selectors, Next: Drawing Area, Prev: Control Panel, Up: Application Window
+
+The Mode Selectors
+------------------
+
+ The mode selector buttons reside below the control panel. They are
+used to select the operation mode of `Pcb'. A mode can be thought of as
+a tool that gets used when *<Btn1>* is pressed. Each mode causes the
+cursor to take on a unique shape that identifies the tool. The buttons
+themselves are icons that illustrate their function. The drawing modes
+can also be selected from the keyboard:
+ *<Key>Escape* reset mode
+ *<Key>F1* via-mode
+ *<Key>F2* line-mode
+ *<Key>F3* pastebuffer-mode
+ *<Key>F4* rectangle-mode
+ *<Key>F5* text-mode
+ *<Key>F6* polygon-mode
+ *<Key>Insert* insert-point-mode
+ *<Key>F7* thermal-mode
+ *<Key>F8* arc-mode
+ The *<Key>Space* cycles through all of the modes in the mode button
+palette.
+
+ Reset-mode is really no mode, and *<Btn1>* has no effect with this
+setting. Some of the modes are very simple, such as the via-mode.
+Clicking *<Btn1>* while in this mode creates a via at the cross-hair
+position. The pastebuffer-mode is similar. With this mode, *<Btn1>*
+copies the contents of the active buffer to the layout, but only those
+parts that reside on visible layers are copied. The rotate-mode allows
+you to rotate elements and text objects 90 degrees counter-clockwise
+with each click. The line-mode is explained in detail in *Note Line
+Objects::. The arc-mode is explained in detainl in *Note Arc Objects::.
+Rectangle-mode, polygon-mode and thermal-mode are explained in detail in
+*Note Polygon Objects::. Remember that the thermal-mode will only
+create and destroy thermals to polygons on the active layer.
+
+ The insert-point-mode is an editing tool that allows you to add
+points into lines or polygons. With version 1.5 of `Pcb', the
+insert-point-mode enforces the 45 degree line rule. You can force only
+the shorter line segment to 45 degrees by holding the shift key down
+while inserting the point. The delete-mode deletes the smallest object
+beneath the cursor with each *<Btn1>* click. If you use click at an
+end-point that two lines have in common, it will replace the two lines
+with a single line spanning the two remaining points. This can be used
+to delete an "inserted" point in a line, restoring the previous line.
+

+
+Drawing Area
+------------
+
+ The drawing area is made from a viewport widget that also includes
+two scrollbars. The cursor changes shape depending on the current
+operation mode when the pointer is moved into the drawing area. A
+crosshair follows the X11 pointer with respect to the grid setting.
+Move around and watch the cursor position displayed in the upper right
+of the window. Now select a new grid from the *Display* menu. The new
+value is updated in the statusline. Now move again and watch the
+difference. A different way to change the grid is *Shift<Key>g* to
+decrease or *<Key>g* to increase it. The grid setting is saved along
+with the data when you save a pcb layout. For homemade layouts a value
+around 50 is a good setting. The cursor also may be moved with the
+cursor keys or, for larger distances, by pressing the *shift* modifier
+together with a cursor key.
+
+
+File: pcb.info, Node: Menu, Prev: Drawing Area, Up: Application Window
+
+Menu
+----
+
+ The menus are located at the top of the drawing area. Most, but not
+all, of their functions are also available from the keyboard. Some of
+the entries such as *center* require a certain cursor position. In
+this case a statusline will popup at the bottom with wording similar to
+the following:
+ move pointer to the appropriate screen position and press a button
+ Any mouse button will do the job, whereas any key except the cursor
+keys will cancel the operation. For details see *Note Actions::.
+
+`About'
+ There is no menu hiding behind this button, but a small
+ information box will pop up.
+
+`File'
+ This menu offers a choice of loading, saving and printing data,
+ saving connection information to a file or quitting the
+ application. You also may change the layout's or the active
+ layer's name. Selecting *print layout* pops up a printer control
+ dialog which is, hopefully, self explaining. This box contains a
+ panner widget (only `X11R5' and later) which simplifies adjusting
+ the offsets. With earlier releases the printout will always appear
+ in the upper left corner with respect to the media margins.
+
+ A selection of several device drivers is available from the
+ printer control dialog. Presently *PostScript*, *encapsulated
+ PostScript*, and *GerberX* are supported. *GerberD* support may be
+ forthcoming. It requires a rastering engine that pcb presently
+ lacks.
+
+`Display'
+ The display menu supports the most needed functions related to
+ screen output. The entries are used to change the grid to some
+ popular values, the zoom factor, the displayed element name and
+ also are used to center or refresh the output. You also may
+ switch grid-displaying on or off and select between absolute grid
+ (origin at (0,0)) or relative grid (origin at the position where
+ the grid has been changed). The relative grid position is now
+ established at the actual pointer position, NOT necessarily the
+ same as the crosshair position. This allows you to shift the grid
+ without changing the grid spacing. I recommend that you zoom in
+ as close as possible before setting a relative grid so that you're
+ sure the grid lines fall where you want. The clipping to
+ 45-degree lines is selected in this menu, as well as enabling
+ rubberband mode (see description of *Mode*).
+
+`Sizes'
+ This menu allows you to select a group of line thickness, via
+ diameter and via drill size (collectively called a "routing
+ style") to be coppied to the "active" sizes. You can also change
+ the names given to these styles and adjust their values from this
+ menu. You can also edit the "active" sizes (the initial size of
+ new vias, drilling holes, lines, text-objects and the current
+ maximum size of the layout) from this menu.
+
+`Objects'
+ Displaying the pinout of an element and changing its names, the one
+ that is currently selected by the *Display* menu, as well as
+ editing a text object is offered by this menu. The latter two
+ selections require an additional pointer button click at the
+ object's position. A dialog for changing the layer groupings is
+ also reached from this menu.
+
+`Selection'
+ This menu covers most of the operations that work with selected
+ objects. You may either (un)select all visible objects of a
+ layout or only the ones which have been found by the last
+ connection scan. The mouse can also be used to change which things
+ are and are not selected: toggle the selection of a single object
+ by pressing *<Btn3Down>* and releasing without moving the mouse.
+ Pressing *Mod1<Btn3Down>*, moving and releasing the button selects
+ all visible objects inside the rectangle. Pressing the modifier
+ key *Shift* too, unselects all objects in the area. You can delete
+ all selected objects from this menu, and also move selected text
+ objects to the silk-screen layer. The other entries change the
+ sizes of visible and selected objects.
+
+`Buffer'
+ This menu handles pastebuffer related actions. You may select one
+ out of five (per viewing side) buffers to use, rotate or clear its
+ contents and paste it to the layout. You can also gather objects
+ in the buffer into an element definition from this menu. Note:
+ only visible objects are pasted to the layout.
+
+`Connections'
+ The entries available through the connections menu button allow
+ the user to find connections from pins or vias and to manipulate
+ these. The connection lists may be saved by selecting entries
+ from the *File* menu. In many cases it is desireable to use the
+ ratsnest function to check connections against a netlist file
+ instead of using the connections menu to generate text connection
+ lists.
+
+`Undo'
+ This menu is a frontend for managing the reversing of operations
+ such as remove, copy, move, name changes, etc. The number of
+ operations is unlimited (depending on memory). The list is cleared
+ if new layout data is loaded or by selecting the appropriate entry
+ from this menu. The inverse operation, redo, is also available.
+
+`Report'
+ This menu allows you to generate a dialog that summerizes
+ information about an object such as sizes and coordinates. You can
+ also get a report about all of the drills that are used on the
+ board.

+Log Window
+==========
+
+ This optional window is used to display all kind of messages
+including the ones written to *stderr* by external commands. The main
+advantage is that its contents are saved in a scrolling list until the
+program exits. Disabling this feature by setting the resource
+*useLogWindow* to *false* will generate popup windows to display
+messages. The *stderr* of external commands will appear on `Pcb's

+Library Window
+==============
+
+ First appearing in 1.4.1 the library window is one of the best new
+features in my opinion. It simplifies loading circuits quiet a lot just
+by selecting the appropriate type from the menu at the top. A circuit
+is then selected by simply double-clicking on the text line. For
+details on libraries check-out *Note Library File:: and *Note Library
+Contents File::.
+
+
+File: pcb.info, Node: Drawing and Removing, Next: Moving and Copying, Prev: Library Window, Up: Getting Started
+
+Drawing and Removing Basic Objects
+==================================
+
+ There are several ways of creating new objects: you may draw them
+yourself, you may copy an existing object or you may load an element
+from a file or library. Creating new objects is normally related to a
+special mode depending on the object type. The notation of key and
+button events is the same as described in the X11 Intrinsics manual.
+
+ The operation mode may be selected by one of the mode selectors in
+the bottom left corner, by one of the function keys listed earlier in
+this chapter, or by pressing the space bar to cycle through the modes.
+*<Btn1Down>* sends a notify request to the application which responds
+by creating or changing the appropriate object or at least takes the
+first step to do so. Switching to a mode causes the cursor to take on a
+unique shape and also causes the cooresponding mode selector button to
+be drawn with thick lines. You can use either cue to see which mode is
+currently selected.
+
+ Removing objects is possible using *<Key>BackSpace* (or *<Key>Delete*
+on some machines) which deletes the object at the cursor location. If
+more than one object is located at the same position, the smallest
+matching type will be chosen. If two or more of the same type are the
+smallest at the position, then the newest one will be deleted. You
+also may change to *remove-mode* and click *<Btn1Down>* at the location
+of the objects which are to be removed. If you "remove" the end-point
+where two lines connect, it will remove the point of connection leaving
+a single line that spans the far end points.
+
+ Rotating works in a similar fashion. Change the mode and press
+*<Btn1Down>* at the object's location. Remember only text, elements and
+arcs can be rotated. (Anything including groups of objects may be
+rotated inside a buffer using the rotate buffer menu option.)
+
+ Insert mode provides the capability of inserting new points into
+existing polygons or lines. The 45 degree line clipping is now enforced
+when selected. Press and hold the shift key while positioning the new
+point to only clip the line segment to the nearer of the two existing
+points to 45 degrees. You can also toggle the 45-degree clipping in
+the middle of a point insertion by pressing the *<Key>.* If the shift
+key is not depressed and the 45 degree line clipping mode is on, both
+new line segments must be on 45 degree angles - greatly restricting
+where the new point may be placed. In some cases this can cause
+confusion as to whether an insertion has been started since the two new
+lines may be forced to lie parallel on top of the original line until
+the pointer is moved far from the end points.
+
+ Removing objects, changing their size or moving them only applies to
+objects that are visible when the command is executed.

+
+ There are several keystrokes and button events refering to an
+*object* without identifying its type. Here's a list of them:
+
+ *<Btn1Down>* creates (or deletes) an object depending on the
+current mode.
+
+ *<Key>BackSpace* or *<Key>Delete* removes the visible object at the
+cursor location. When more than one object exists at the location, the
+order of removal is: via, line, text, polygon and element. The drawn
+layer order also affects the search - whatever is top - most (except
+elements) is affected before lower items. Basically all this means
+that what is removed is probably just what you expect. If for some
+reason it isn't, undo and try again. Only one object is removed for
+each keystroke. If two or more of the same type match, the newest one
+is removed.
+
+ Use *<Key>s* and *Shift<Key>s* to change the size (width) of lines,
+arcs, text objects, pins, pads and vias, or to toggle the style of
+polygons (whether pins and vias automatically have clearances).
+
+ *<Key>n* changes the name of pins, pads, vias, the string of a text
+object, or the currently displayed label of an element.
+
+ *<Key>m* moves the line, arc, or polygon under the crosshair to the
+active layer if it wasn't on that layer already.
+
+ *<Key>u* (undo) recovers from an unlimited number of operations such
+as creating, removing, moving, copying, selecting etc. It works like
+you'd expect even if you're in the midst of creating something.
+
+ *Shift<Key>r* restores the last undone operation provided no other
+changes have been made since the undo was performed.
+
+ *<Key>tab* changes the board side you are viewing.
+
+ For a complete list of keystrokes and button events see *Note
+Translations::.

+File: pcb.info, Node: Lines, Next: Arcs, Prev: Common, Up: Drawing and Removing
+
+Lines
+-----
+
+ To draw new lines you have to be in *line-mode*. Get there either by
+selecting it from the *Tool palette* or by pressing *<Key>F2*. Each
+successive *notify* event creates a new line. The adjustment to 45
+degree lines is done automatically if it is selected from the *Display*
+menu. You can toggle the 45 degree mode setting by pressing the
+*<Key>.* (That is the period key). When 45 degree enforcement is turned
+on there are three distinct modes of line creation: a single line on
+the closest 45 degree vector towards the crosshair (but not necessarily
+actually ending at the crosshair), two lines created such that the
+first leaves the start point on a 90 degree vector and the second
+arrives at the crosshair on a 45 degree vector, and finally two lines
+created such that the first leaves the start point on a 45 degree
+vector and the second arrives at the crosshair on a 90 degree vector.
+These last two modes always connect all the way from the start and end
+points, and all lines have angles in 45 degree multiples. The *<Key>/*
+cycles through the three modes. The status line shows a text icon to
+indicate which of the modes is active and the lines following the
+crosshair motion show the outline of the line(s) that will actually be
+created. Press *<Key>Escape* to leave line-mode.
+
+ *<Key>l*, *Shift<Key>l* and the entries in the *Sizes* menu change
+the initial width of new lines. This width is also displayed in the
+status line.
+
+
+File: pcb.info, Node: Arcs, Next: Polygons, Prev: Lines, Up: Drawing and Removing
+
+Arcs
+----
+
+ An Arc is drawn with the *arc-tool*. Get there either by selecting
+it from the *Tool palette* or by pressing *<Key>F8*. Press *Btn1* to
+define the starting point for the arc. Drag the mouse towards the
+desired end point along the path you want the arc to follow. The
+outline of the arc that will be created is shown on the screen as you
+move the mouse. Arcs are always forced to be 90 degrees and have
+symmetrical length and width ( i.e. they are a quarter circle). The
+next *Btn1* click creates the arc. It will have the same width as new
+lines (displayed in the status line) and appear on the active layer.
+The arc leaves the starting point towards the crosshair along the axis
+whose distance from the crosshair is largest. Normally this means that
+if you drag along the path you want the arc to follow, you'll get what
+you want. If the grid is set to the arc radius, then the two distances
+will be equal and you won't be able to get all of the possible
+directions. If this is thwarting your desires, reduce the grid spacing
+(*!Shift<Key>G*) and try again.
+
+
+File: pcb.info, Node: Polygons, Next: Text, Prev: Arcs, Up: Drawing and Removing
+
+Polygons and Rectangles
+-----------------------
+
+ A polygon is drawn by defining all of its segments as a series of
+consecutive line segments. If the first point matches a new one and if
+the number of points is greater than two, then the polygon is closed.
+Since matching up with the first point may be difficult, you may use
+*Shift<Key>p* to close the polygon. The *Shift<Key>p* won't work if
+clipping to 45 degree lines is selected and the final segment cannot
+match this condition. I suggest you create simple convex polygons in
+order to avoid a strong negative impact on the performance of the
+connection scanning routines. The *rectangle-mode* is just an easy way
+to generate rectangular polygons. *Polygon-mode* also is selected by
+*<Key>F6* whereas *rectangle-mode* uses *<Key>F4*. Pressing a
+*<Btn1Down>* at two locations creates a rectangle by defining two of
+its corners. *<Key>Insert* brings you to *insert-point-mode* which
+lets you add additional points to an already existing polygon. Single
+points may be removed by moving the crosshair to them and selecting one
+of the delete actions *(remove-mode, BackSpace, or Delete*. This only
+works if the remaining polygon will still have three or more corners.
+Pressing *<Key>u* or *<Key>p* while entering a new polygon brings you
+back to the previous corner. Removing a point does not force clipping
+to 45 degree angles (because it's not generally possible). Newly
+created polygons will not connect to pins or vias that pierce it unless
+you create a thermal (using the thermal mode) to make the connection.
+If the edge of a polygon gets too close to a pin or via that lies
+outside of it, a warning will be issued and the pin will be given a
+special color. Increasing the distance between them will remove the
+warning color.

+Text
+----
+
+ Pressing *<Key>F5* or clicking one of the text selector buttons
+changes to *text-mode*. Each successive notify event (*<Btn1Down>*)
+pops up the input line at the bottom and queries for a string. Enter
+it and press *<Key>Return* to confirm or *<Key>Escape* to abort. The
+text object is created with its upper left corner at the current pointer
+location. The initial scaling is changed by *<Key>t* and *Shift<Key>t*
+or from the *Sizes* menu.
+
+ Now switch to *rotate-mode* and press *<Btn1Down>* at the
+text-objects location. Text objects on the solder side of the layout
+are automatically mirrored and flipped so that they are seen correctly
+when viewing the solder-side.
+
+ Use *<Key>n* to edit the string.
+
+ TEXT OBJECTS ON COPPER LAYERS CREATE COPPER LINES BUT THEY ARE NOT
+SCANNED FOR CONNECTIONS. If they are moved to the silkscreen layer, they
+no longer create copper.

+Vias
+----
+
+ The initial size of new vias may be changed by *<Key>v* and
+*Shift<Key>v* or by selecting the appropriate entry from the *Sizes*
+menu. *Mod1<Key>v* and *Mod1 Shift<Key>v* do the same for the drilling
+hole of the via. The statusline is updated with the new values.
+Creating a via is similar to the other objects. Switch to *via-mode* by
+using either the selector button or *<Key>F1* then press *<Key>]* or
+*<Btn1Down>* to create one. *<Key>n* changes the name of a via. If you
+want to create a mounting hole for your board, then you can place a via
+where you want the hole to be then convert the via into a hole. The
+conversion is done by pressing *!Ctrl<Key>h* with the crosshair over
+the via. Conceptually it is still a via, but it has no copper annulus.
+If you create such a hole in the middle of two polygons on different
+layers, it will short the layers. Theoretically you could arrange for
+such a hole not to be plated, but a metal screw inserted in the hole
+would still risk shorting the layers. A good rule is to realize that
+holes in the board really are vias between the layers and so place them
+where they won't interfere with connectivity. You can convert a hole
+back into a normal via with the same keystroke used to convery it in
+the first place.

+Elements
+--------
+
+ Some of the functions related to elements only work if both the
+package layer and the pin layer are switched on.
+
+ Now that you're familiar with many of the basic commands, it is time
+to put the first element on the layout. First of all, you have to load
+data into the paste buffer. There are four ways to do this:
+ 1) load the data from a library
+ 2) load the data from a file
+ 3) copy data from an already existing element
+ 4) convert objects in the buffer into an element
+ We don't have any elements on the screen yet nor anything in the
+buffer, so we use number one.
+
+ Select *lsi* from the menu in the library window press *<Btn1Down>*
+twice at the appropriate text-line to get the MC68030 CPU. The data is
+loaded and the mode is switched to *pastebuffer-mode*. Each notify
+event now creates one of these beasts. Leave the mode by selecting a
+different one or by *<Key>Escape* which resets all modes.. The
+crosshair is located at the *mark* position as defined by the data
+file. Rotating the buffer contents is done by selecting the *rotate*
+entry of the *Buffer* menu or by pressing *Shift<Key>F3*. The contents
+of the buffer are valid until new data is loaded into it either by a
+cut-to-buffer operation, copy-to-buffer operation or by loading a new
+data file. There are 5 buffers available. Switching between them is
+done by selecting a menu entry or by *Shift<Key>1..5*. Each of the two
+board sides has its own buffers.
+
+ The release includes all data files for the circuits that are used
+by the demo layout. The elements in the LED example are not found in
+the library, but you can lift them from the example itself if you want.
+If you have problems with the color of the crosshair, change the
+resource *crosshairColor* setting to a different one.
+
+ Now load a second circuit, the MC68882 FPU for example. Create the
+circuit as explained above. You now have two different unnamed
+elements. Unnamed means that the layout-name of the element hasn't been
+set yet. Selecting *description* from the *Display* menu displays the
+description string of the two circuits which are CPU and FPU. The
+values of the circuits are set to MC68030 and MC68882. Each of the
+names of an element may be changed by *<Key>n* at the elements location
+and editing the old name in the bottom input line. Naming pins and vias
+is similar to elements. You can hide the element name so that it won't
+appear on the board silkscreen by pressing *<key>h* with the cursor
+over the element. Doing so again un-hides the element name.
+
+ Entering `:le' and selecting an element data file is the second way
+to load circuits.
+
+ The third way to create a new element is to copy an existing one.
+Please refer to *Note Moving and Copying::.
+
+ The fourth way to create a new element is to convert a buffer's
+contents into an element. Here's how it's done: Select the Via-tool
+from the *Tool pallette*. Set the grid spacing to something
+appropriate for the element pin spacing. Now create a series of vias
+where the pins go. Create them in pin number order. It is often handy
+to place a reference point (*!Ctrl<Key>m*) in the center of the first
+pin in order to measure the location of the other pins. Next make a
+solder-side layer the active layer from the *active-layer* popup menu.
+Now draw the outline of the element using lines and arcs. When you're
+done, select everything that makes up the element with a box selection
+(*<Btn3Down> drag, <Btn3Up>*). Now select "cut selection to buffer"
+from the *Buffer* menu. Position the cursor over the center of pin 1
+and press the left button to load the data into the buffer. Finally
+select "convert buffer to element" from the *Buffer* menu. You'll only
+want to create elements this way if they aren't already in the library.
+It's also probably a good idea to do this before starting any of the
+other aspects of a layout, but it isn't necessary.
+
+ To display the pinout of a circuit move to it and press *Shift<Key>d*
+or select *show pinout* from the *Objects* menu. A new window pops up
+and displays the complete pinout of the element. This display can be
+difficult to read if the component has been rotated 90 degrees :-(
+therefore, the new window will show an un-rotated view so the pin names
+are readable. *<Key>d* displays the name of one or all pins/pads
+inside the drawing area, this is only for display on-screen, it has no
+effect on any printing of the layout.
+
+ You also may want to change a pin's or pad's current size by pressing
+*<Key>s* to increase or *Shift<Key>s* to decrease it. While this is
+possible, it is not recommended since care was probably taken to define
+the element structure in the first place. You can also change the
+thickness of the element's silkscreen outline with the same keys. You
+can change whether a pin or SMD pad is rounded or square with the
+*<Key>q*. SMD pads should usually have squared ends. Finally, you can
+change whether the non-square pins are round or octagonal with the
+*!Ctrl<Key>o*.
+
+ SMD elements and silkscreen objects are drawn in the "invisible
+object" color if they are located on the opposite side of the board.

+Pastebuffer
+-----------
+
+ The linestack and element-buffer of former releases have been
+replaced by 5 multi-purpose buffers that are selected by
+*Shift<Key>1..5*. The status line shows which buffer is the active one.
+You may load data from a file or layout into them. Cut-and-paste works
+too. If you followed the instructions earlier in this chapter you
+should now have several objects on the screen. Move the crosshair to
+one of them and press *<Btn3Down>* to toggle its selection flag. (If
+you drag the mouse while the button is down, a box selection will be
+attempted instead of toggling the selection.) The object is redrawn in
+a different color. You also may want to try moving the pointer while
+holding the third button down and release it on a different location.
+This selects all objects inside the rectangle and unselects everything
+else. If you want to add a box selection to an existing selection,
+drag with *Mod1<Btn3Down>* instead. Dragging *Shift Mod1<Btn3Down>*
+unselects objects in a box. Now change to *pastebuffer-mode* and
+select some operations from the *Buffer* menu. Copying objects to the
+buffer is available as *Mod1<Key>c* while cutting them uses
+*Mod1<Key>x* as shortcut. Both clear the buffer before new data is
+added. If you use the menu entries, you have to supply a crosshair
+position by pressing a mouse button. The objects are attached to the
+pastebuffer relative to that crosshair location. Element data or PCB
+data may be merged into an existing layout by loading the datafiles
+into the pastebuffer. Both operations are available from the *File*
+menu or as user commands.

+Moving and Copying
+==================
+
+ All objects can be moved including element-names, by *<Btn2Down>*,
+draging the pointer while holding the button down and releasing it at
+the new location of the object. If you use *Mod1<Btn2Down>* instead,
+the object is copied. Copying does not work for element-names of
+course. You can move all selected objects with *Shift <Btn1Down>*.
+This uses the Pastebuffer, so it will remove whatever was previously in
+the Pastebuffer. Please refer to *Note Pastebuffer::. If you want to
+give a small nudge to an object, but you don't think that the mouse
+will give you the fine level of control that you want, you can position
+the cursor over the object, press *<Key>[*, move it with the arrow
+keys, then press *<Key>]* when it's at the desired position. Remember
+that all movements are forced onto grid coordinates, so you may want to
+change the grid spacing first.

+
+Loading and Saving
+==================
+
+ After your first experience with `Pcb' you will probably want to save
+your work. `:s name' passes the data to an external program which is
+responsible for saving it. For details see *saveCommand* in *Note
+Resources::. Saving also is available from the *File* menu, either
+with or without supplying a filename. `Pcb' reuses the last filename if
+you do not pass a new one to the save routine.
+
+ To load an existing layout either select *load layout data* from the
+*File* menu or use `:l filename'. A file select box pops up if you
+don't specify a filename. Merging existing layouts into the new one is
+supported either by the *File* menu or by `:m filename'.
+
+ `Pcb' saves a backup of the current layout depending on the resource
+*backup*. The file is named `/tmp/PCB.%i.backup'. During critical
+sections of the program or when data would be lost it is saved as
+`/tmp/PCB.%i.save'. *%i* is replaced by the process ID.
+
+
+File: pcb.info, Node: Printing, Next: Connection Lists, Prev: Loading and Saving, Up: Getting Started
+
+Printing
+========
+
+ `Pcb' now has support for device drivers, `PostScript',
+*encapsulated PostScript*, and *Gerber X* drivers are available so far.
+The *Gerber X* driver generates a NC drill file for automated drilling.
+I recommend the use of `GhostScript' if you don't have a `PostScript'
+printer for handling the PostScript output. Printing always generates a
+complete set of files for a specified driver. See the page about the
+*Print()* action for addtional information about the filenames. The
+control panel offers a number of options. Most of them are not avilable
+for Gerber output because it wouldn't make sense, for example, to
+scale the gerber output (you'd get an incorrectly made board!) The
+options are:
+
+`device'
+ The top menu button selects from the available device drivers.
+
+`rotate'
+ Rotate layout 90 degrees counter-clockwise before printing
+ (default).
+
+`mirror'
+ Mirror layout before printing. Use this option depending on your
+ production line.
+
+`color'
+ Created colored output. All colors will be converted to black if
+ this option is inactive.
+
+`outline'
+ Add a board outline to the output file. The size is determined by
+ the maximum boardsize changeable from the *sizes* menu. The
+ outline appears on the top and bottom sides of the board, but not
+ on the internal layers. An outline can be useful for determining
+ where to shear the board from the panel, but be aware that it
+ creates a copper line. Thus it has the potential to cause short
+ circuits if you don't leave enough room from your wiring to the
+ board edge. Use a viewer to see what the output outline looks like
+ if you want to know what it looks like.
+
+`alignment'
+ Additional alignement targets are added to the output. The
+ distances between the board outline is set by the resource
+ *alignmentDistance*. Alignment targets should only be used if you
+ know for certain that YOU WILL BE USING THEM YOURSELF. It is
+ extremely unlikely that you will want to have alignment targets if
+ you send gerber files to a commercial pcb manufacture to be made.
+
+`scaling'
+ It's quite useful to enlarge your printout for checking the layout.
+ Use the scrollbar to adjust the scaling factor to your needs.
+
+`media'
+ Select the size of the output media from this menu. The user
+ defined size may be set by the resource *media* either from one of
+ the well known paper sizes or by a `X11' geometry specification.
+ This entry is only available if you use `X11R5' or later. For
+ earlier releases the user defined size or, if not available, *A4*
+ is used. Well known size are:
+ A3
+ A4
+ A5
+ letter
+ tabloid
+ ledger
+ legal
+ executive
+
+`offset'
+ Adjust the offsets of the printout by using the panner at the
+ right side of the dialog box. This entry is only available if you
+ use `X11R5' or later. A zero offset is used for earlier releases.
+
+`8.3 filenames'
+ Select this button to generate DOS compatible filenames for the
+ output files. The *command* input area will disappear if selected.
+
+`commandline'
+ Use this line to enter a command (starts with `|') or a filename.
+ A %f is replaced by the current filename. The default is set by
+ the resource *printCommand*.
+
+ The created file includes some labels which are guaranteed to stay
+unchanged
+`PCBMIN'
+ identifies the lowest x and y coordinates in mil.
+
+`PCBMAX'
+ identifies the highest x and y coordinates in mil.
+
+`PCBOFFSET'
+ is set to the x and y offset in mil.
+
+`PCBSCALE'
+ is a floating point value which identifies the scaling factor.
+
+`PCBSTARTDATA'
+`PCBENDDATA'
+ all layout data is included between these two marks. You may use
+ them with an `awk' script to produce several printouts on one
+ piece of paper by duplicating the code and putting some
+ `translate' commands in front. Note, the normal `PostScript'
+ units are 1/72 inch.

+
+Connection Lists
+================
+
+ After completing parts of your layout you may want to check if all
+drawn connections match the ones you have in mind. This is probably
+best done in conjunction with a net-list file: see *Note Rats Nest::.
+The following examples give more rudimentary ways to examine the
+connections.
+ 1) create at least two elements and name them
+ 2) create some connections between their pins
+ 3) optionally add some vias and connections to them
+
+ Now select *lookup connection* from the *Connections* menu, move the
+cursor to a pin or via and press any mouse button. `Pcb' will look for
+all other pins and/or vias connected to the one you have selected and
+display the objects in a different color. Now try some of the reset
+options available from the same menu.
+
+ There also is a way to scan all connections of one element. Select
+*a single element* from the menu and press any button at the element's
+location. All connections of this element will be saved to the
+specified file. Either the layout name of the element or its canonical
+name is used to identify pins depending on the one which is displayed
+on the screen (may be changed by *Display* menu).
+
+ An automatic scan of all elements is initiated by choosing *all
+elements*. It behaves in a similar fashion to scanning a single element
+except the resource *resetAfterElement* is used to determine if
+connections should be reset before a new element is scanned. Doing so
+will produce very long lists because the power lines are rescanned for
+every element. By default the resource is set to *false* for this
+reason.
+
+ To scan for unconnected pins select *unused pins* from the same menu.

+
+Selection
+=========
+
+ Some commands mentioned earlier in this chapter also are able to
+operate on all selected and visible objects. Now go back to the layout
+and toggle the selection flag of a single one by *<Btn3Down>*. Try
+*<Btn3Down>*, move the pointer while holding the button down and
+release it on a different location. This selects all objects inside
+the rectangle and unselects everything else. Dragging with
+*Mod1<Btn3Down>* adds everything in the box to the existing selection.
+Dragging *Shift <Btn3Down>* unselects objects in the box.
+
+ The entries of the *Selection* menu are hopefully self-explanatory.
+Many of the *Action Commands* can take various key words that make them
+function on all or some of the selected items.

+
+Rats Nest
+=========
+
+ If you have a netlist that corresponds to the layout you are working
+on, you can use the rats-nest feature to add rat-lines to the layout.
+First you will need to load a netlist file (see *:rn*, *Note User
+Commands::). *<Key>w* adds rat-lines on the active layer using the
+current line thickness shown in the status line (usually you'll want
+them to be thin lines). Only those rat-lines that fill in missing
+connectivity (since you have probably routed some connections already)
+are added. If the layout is already completely wired, nothing will be
+added, and you will get a message that the wiring is complete.
+
+ Rat-lines are lines having the special property that they only
+connect to pins and pads at their end points. Rat-lines are drawn on
+the screen with a stippled pattern to make them easier to identify
+since they have special behavior and cannot remain in a completed
+layout. Rat-lines are added in the minimum length straight-line tree
+pattern (always ending on pins or pads) that satisfies the missing
+connectivity in the circuit. Used in connection with moves and rotates
+of the elements, they are extremely useful for deciding where to place
+elements on the board. The rat-lines will always automatically
+rubberband to the elements whether or not the rubberband mode is on.
+The only way for you to move them is by moving the parts they connect
+to. This is because it is never desireable to have the rat-lines
+disconnected from their element pins. Rat-lines will normally
+criss-cross all over which gives rise to the name "rats nest"
+describing a layout connected with them. If a SMD pad is unreachable
+on the active layer, a warning will be issued about it and the rat-line
+to that pad will not be generated.
+
+ A common way to use rats nests is to place some elements on the
+board, add the rat-lines, and then use a series of moves/rotates of the
+elements until the rats nest appears to have minimum tangling. You may
+want to iterate this step several times. Don't worry if the layout
+looks messy - as long as you can get a sense for whether the
+criss-crossing is better or worse as you move things, you're fine.
+After moving some elements arround, you may want to optimize the rats
+nest *<Key>o* so that the lines are drawn between the closest points
+(this can change once you've moved components). Adding rat-lines only
+to selected pads/pins (*Shift<Key>w*) is often useful to layout a
+circuit a little bit at a time. Sometimes you'll want to delete all
+the rat-lines (*<Key>e*) or selected rat-lines (*Shift<Key>e*) in order
+to reduce confusion. With a little practice you'll be able to achieve
+a near optimal component placement with the use of a rats nest.
+
+ Rat-lines are not only used for assisting your element placement,
+they can also help you to route traces on the board. Use the *<Key>m*
+to convert a rat-line under the cursor into a normal line on the active
+layer. Inserting a point into a rat-line will also cause the two new
+lines to be normal lines on the board. Another way that you can use
+rat-lines is to use the *<Key>f* with the cursor over a pad or pin.
+All of the pins and pads and rat-lines belonging to that net will be
+highlighted. This is a helpful way to distinguish one net from the rest
+of the rats nest. You can then route those tracks, turn off the
+highlighting (*Shift<Key>f*) and repeat the process. This will work even
+if the layer that the rat-lines reside on is made invisible - so only
+the pins and pads are highlighted. Be sure to erase the rat-lines
+(*<Key>e* erases them all) once you've duplicated their connectivity by
+adding your own lines. When in doubt, the *<Key>o* will delete only
+those rat-lines that are no longer needed.
+
+ If connections exist on the board that are not listed in the netlist
+when *<Key>w* is pressed, warning messages are issued and the affected
+pins and pads are drawn in a special *warnColor* until the next
+*Notify()* event. If the entire layout agrees completely with the
+netlist, a message informs you that the layout is complete and no
+rat-lines will be added (since none are needed). If the layout is
+complete, but still has rat-lines then you will be warned that
+rat-lines remain. If you get no message at all it's probably because
+some elements listed in the net list can't be found and where reported
+in an earlier message. There shouldn't be any rat-lines left in a
+completed layout, only normal lines.
+
+ The *Shift<Key>w* is used to add rat-lines to only those missing
+connections among the selected pins and pads. This can be used to add
+rat-lines in an incremental manner, or to force a rat-line to route
+between two points that are not the closest points within the net.
+Often it is best to add the rats nest in an incremental fashion, laying
+out a sub-section of the board before going further. This is easy to
+accomplish since new rat-lines are never added where routed
+connectivity already makes the necessary connections.
+
+
+File: pcb.info, Node: Design Rule Checking, Prev: Rats Nest, Up: Getting Started
+
+Design Rule Checking
+====================
+
+ After you've finished laying out a board, you may want to check to
+be certain that none of your interconnections are too closely spaced or
+too tenuously touching to be reliably fabricated. The design rule
+checking (DRC) function does this for you. Use the command ":DRC()"
+(without the quotes of course) to invoke the checker. If there are no
+problem areas, you'll get a message to that effect. If any problem is
+encountered, you will get a message about it and the affected traces
+will be highlighted. One part of the tracks of concern will be
+selected, while the other parts of concern will have the
+"FindConnection" highlighting. The screen will automatically be
+centered in the middle of the object having the "FindConnection"
+(Green) highlighting. The middle of the object is also the coordinates
+reported to be "near" the problem. The actual trouble region will be
+somewhere on the boundary of this object. If the two parts are from
+different nets then there is some place where they approach each other
+closer than the minimum rule. If the parts are from the same net, then
+there is place where they are only barely connected. Find that place
+and connect them better.
+
+ After a DRC error is found and corrected you must run the DRC again
+because the search for errors is halted as soon as the first problem is
+found. Unless you've been extremely careless there should be no more
+than a few design rule errors in your layout. The DRC checker does not
+check for minimum spacing rules to copper text, so always be very
+careful when adding copper text to a layout. The rules for the DRC are
+specified in the application resource file. The minimum spacing value
+(in mils) is given by the *Settings.Bloat* value. The default is 7
+mils. The minimum touching overlap (in mils) is given by the
+*Settings.Shrink* value. This value defaults to 5 mils. Check with your
+fabrication process people to determine the values that are right for
+you.
+
+ If you want to turn off the highlighting produced by the DRC,
+perform an undo (assuming no other changes have been made). To restore
+the highlighting, use redo. The redo will restore the highlighting
+quickly without re-running the DRC checker.

+User Commands
+*************
+
+ The entering of user-commands is initiated by the action routine
+*Command()* (the `(":")' character) and finished by either *<Key>Return*
+or *<Key>Escape* to confirm or to abort. These two keybindings cannot
+be changed from the resource file. The triggering event, normally a
+key press, is ignored. The input area will replace the bottom
+statusline. It pops up when *Command()* is called. The arguments of the
+user-commands are passed to the external commands without modification.
+See also, the resource *saveInTMP*.
+
+ There are simple *usage* dialogs for each command and one for the
+complete set of commands.
+
+`l [filename]'
+ Loads a new datafile (layout) and, if confirmed, overwrites any
+ existing unsaved data. The filename and the searchpath
+ (*filePath*) are passed to the command defined by *fileCommand*.
+ If no filename is specified a file select box will popup.
+
+`le [filename]'
+ Loads an element description into the paste buffer. The filename
+ and the searchpath (*elementPath*) are passed to the command
+ defined by *elementCommand*. If no filename is specified a file
+ select box will popup.
+
+`m [filename]'
+ Loads an layout file into the paste buffer. The filename and the
+ searchpath (*filePath*) are passed to the command defined by
+ *fileCommand*. If no filename is specified a file select box will
+ popup.
+
+`q[!]'
+ Quits the program without saving any data (after confirmation).
+ q! doesn't ask for confirmation, it just quits.
+
+`s [filename]'
+ Data and the filename are passed to the command defined by the
+ resource *saveCommand*. It must read the layout data from *stdin*.
+ If no filename is entered, either the last one is used again or,
+ if it is not available, a file select box will pop up.
+
+`rn [filename]'
+ Reads in a netlist file. If no filename is given a file select
+ box will pop up. The file is read via the command defined by the
+ *RatCommand* resource. The command must send its output to
+ *stdout*. The netlist received by pcb must have this simple text
+ form:
+
+ netname NAME-PINNUM NAME2-PINNUM2 NAME3-PINNUM3 ... [\]
+
+ where "netname" is the name of the net (currently its value is
+ ignored but it must be present nonetheless), NAME is the
+ layout-name given to an element, and PINNUM is the (usually
+ numeric) pin number of the element that is part of the net (see
+ *Note Element Objects:: for details on pin numbering). Spaces or
+ tabs separate the fields. If the line ends with a "\" the net
+ continues on the next line and the "\" is treated exactly as if it
+ were a space. If the NAME ends with a lower-case letter, all
+ lower-case letters are stripped from end of the NAME to determine
+ the matching name-on-board name. For example:
+
+ Data U1-3 U2abc-4 FLOP1a-7 Uabc3-A9
+
+ would specifiy that pin 3 of U1 be connected to pin 4 of U2, to
+ pin 7 of FLOP1 and to pin A9 of Uabc3. Note that if pin numbers
+ contain alphabetic characters, they must match the case contained
+ in the "number" string defining the pin number on the
+ cooresponding element. It is up to you to name the elements so
+ that their layout-names agrees with the netlist. Netlists are
+ used for generating rats nest (see *Note Rats Nest::) and for
+ verifying the board layout (which is also accomplished by the
+ *Ratsnest* command.
+
+`w[q] [filename]'
+ These commands have been added for the convenience of `vi' users
+ and have the same functionality as *s* combined with *q*.
+
+`actionCommand'
+ Causes the actionCommand to be executed. This allows you to
+ initiate actions for which no bindings exist in the resource file.
+ It can be used to initiate any action with whatever arguments you
+ enter. This makes it possible to do things that otherwise would
+ be extremely tedious. For example, to change the drilling hole
+ diameter of all vias in the layout to 32 mils, you could select
+ everything using the selection menu, then type
+ "*:ChangeDrillSize(SelectedVias, 32)*". (This will only work
+ provided the via's diameter is sufficiently large to accomodate a
+ 32 mil hole). Another example might be to set the grid to 1 mil
+ by typing "*:SetValue(Grid, 1)*". Note that some actions use the
+ current cursor location, so be sure to place the cursor where you
+ want before entering the command. This is one of my favorite new
+ features in 1.5 and can be a powerful tool. Study the *Note
+ Actions:: section to see what actions are available.

+
+Non-Standard X11 Application Resources
+======================================
+
+ In addition to the toolkit resources, `Pcb' defines the following
+resources:
+
+`absoluteGrid (boolean)'
+ Selects if either the grid is relative to the position where it
+ has changed last or absolute, the default, to the origin (0,0).
+
+`alignmentDistance (dimension)'
+ Specifies the distance between the boards outline to the alignment
+ targets.
+
+`allDirectionLines (boolean)'
+ Enables (default) or disables clipping of new lines to 45 degree
+ angles.
+
+`backupInterval (int)'
+ `Pcb' has an automatic backup feature which saves the current data
+ every n seconds. The default is *300* seconds. A value of zero
+ disables the feature. The backup file is named
+ `/tmp/PCB.%i.backup'. *%i* is replaced by the process ID. See
+ also, the command-line option *-backup*.
+
+`Bloat (dimension)'
+ Specifies the minimum spacing design rule in mils.
+
+`charactersPerLine (int)'
+ `Pcb' uses this value to determine the page width when creating
+ lists. N, the number of characters per line, defaults to *80*.
+ See also, the command-line option *-c*.
+
+`connectedColor (color)'
+ All pins, vias, lines and rectangles which are selected during a
+ connection search are drawn with this color. The default value is
+ determined by *XtDefaultForeground*.
+
+`crosshairColor (color)'
+ This color is used to draw the crosshair cursor. The color is a
+ result of a *XOR* operation with the contents of the drawing area.
+ The result also depends on the default colormap of the `X11'
+ server because only the colormap index is used in the boolean
+ operation and `Pcb' doesn't create its own colormap. The default
+ setting is *XtDefaultForeground*.
+
+`elementColor (color)'
+`elementSelectedColor (color)'
+ The elements package part is drawn in these colors, for normal and
+ selected mode, respectively, which both default to
+ *XtDefaultForeground*.
+
+`elementCommand (string)'
+ `Pcb' uses a user defined command to read element files. This
+ resources is used to set the command which is executed by the
+ users default shell. Two escape sequences are defined to pass the
+ selected filename (%f) and the current search path (%p). The
+ command must write the element data to its standard output. The
+ default value is
+ M4PATH="%p";export M4PATH;echo 'include(%f)' | m4
+ Using the GNU version of `m4' is highly recommended. See also,
+ the command-line option *-lelement*.
+
+`elementPath (string)'
+ A colon separated list of directories or commands (starts with
+ '|'). The path is passed to the program specified in
+ *elementCommand* together with the selected elementname. A
+ specified command will be executed in order to create entries for
+ the fileselect box. It must write its results to *stdout* one
+ entry per line. See also, the user-command *le[!]*.
+
+`fileCommand (string)'
+ The command is executed by the user's default shell whenever
+ existing layout files are loaded. Data is read from the command's
+ standard output. Two escape sequences may be specified to pass
+ the selected filename (%f) and the current search path (%p). The
+ default value is:
+ cat %f
+ See also, the command-line option *-lfile*.
+
+`filePath (string)'
+ A colon separated list of directories or commands (starts with
+ '|'). The path is passed to the program specified in
+ *fileCommand* together with the selected filename. A specified
+ command will be executed in order to create entries for the
+ fileselect box. It must write its results to *stdout* one entry
+ per line. See also, the user-command *l[!]*.
+
+`fontCommand (string)'
+ Loading new symbol sets also is handled by an external command.
+ You again may pass the selected filename and the current search
+ path by passing %f and %p in the command string. Data is read from
+ the commands standard output. This command defaults to
+ cat %f
+ See also, the command-line option *-lfont*.
+
+`fontFile (string)'
+ The default font for new layouts is read from this file which is
+ searched in the directories as defined by the resource *fontPath*.
+ Searching is only performed if the filename does not contain a
+ directory component. The default filename is `default_font'. See
+ also, the command-line option *-fontfile*.
+
+`fontPath (string)'
+ This resource, a colon separated list of directories, defines the
+ searchpath for font files. See also, the resource *fontFile*.
+
+`grid (int)'
+ This resources defines the initial value of one cursor step. It
+ defaults to *100 mil* and any changes are saved together with the
+ layout data.
+
+`gridColor (color)'
+ This color is used to draw the grid. The color is a result of a
+ *INVERT* operation with the contents of the drawing area. The
+ result also depends on the default colormap of the `X11' server
+ because only the colormap index is used in the boolean operation
+ and `Pcb' doesn't create its own colormap. The default setting is
+ *XtDefaultForeground*.
+
+`elementColor (color)'
+ Elements localted on the opposite side of the board are drawn in
+ this color. The default is *XtDefaultForeground*.
+
+`layerColor1..8 (color)'
+`layerSelectedColor1..8 (color)'
+ These resources define the drawing colors of the different layers
+ in normal and selected state. All values are preset to
+ *XtDefaultForeground*.
+
+`layerGroups (string)'
+ The argument to this resource is a colon separated list of comma
+ separated layernumbers (1..8). All layers within one group are
+ switched on/off together. The default setting is *1:2:3:...:8*
+ which means all layers are handled separatly. Grouping layers one
+ to three looks like *1,2,3:4:...:8* See also, the command-line
+ option *-lg*.
+
+`layerName1..8 (string)'
+ The default name of the layers in a new layout are determined by
+ these resources. The defaults are empty strings.
+
+`libraryCommand (string)'
+ `Pcb' uses a command to read element data from libraries. The
+ resources is used to set the command which is executed by the users
+ default shell. Three escape sequences are defined to pass the
+ selected filename (%f), the current search path (%p) as well (%a)
+ as the three parameters *template*, *value* and *package* to the
+ command. It must write the element data to its standard output.
+ The default value is
+ /usr/X11R6/lib/X11/pcb/QueryLibrary.sh %p %f %a
+
+`libraryContentsCommand (string)'
+ Similar to *libraryCommand*, `Pcb' uses the command specified by
+ this resource to list the contents of a library.
+ /usr/X11R6/lib/X11/pcb/ListLibraryContents.sh %p %f
+ is the default.
+
+`libraryFilename (string)'
+ The resource specifies the name of the library. The default value
+ is *pcblib*.
+
+`libraryPath (string)'
+ A colon separated list of directories that will be passed to the
+ commands specified by *elementCommand* and
+ *elementContentsCommand*.
+
+`lineThickness (dimension)'
+ The value, int the range [1..250], defines the initial thickness
+ of new lines. The value is preset to *ten mil*.
+
+`media (<predefined> | <width>x<height>+-<left_margin>+-<top_margin>)'
+ The default (user defined) media of the `PostScript' device.
+ Predefined values are *a3*, *a4*, *a5*, *letter*, *tabloit*,
+ *ledger*, *legal*, and *executive*. The second way is to specify
+ the medias width, height and margins in mil. The resource
+ defaults to *a4* size.
+
+`offLimitColor (color)'
+ The area outside the current maximum settings for width and height
+ is drawn with this color. The default value is determined by
+ *XtDefaultBackground*.
+
+`pinColor (color)'
+`pinSelectedColor(color)'
+ This resource defines the drawing color of pins and pads in both
+ states. The values are preset to *XtDefaultForeground*.
+
+`pinoutFont (string)'
+ This fonts are used to display pin names. There is one font for
+ each zoom value. The values are preset to *XtdefaultFont*.
+
+`pinoutNameLength (int)'
+ This resource limits the number of characters which are displayed
+ for pin names in the pinout window. By default the string length
+ is limited to *eight* characters per name. See also, the
+ command-line option *-pnl*.
+
+`pinoutOffsetX (int)'
+`pinoutOffsetY (int)'
+ These resources determine the offset in *mil* of the circuit from
+ the upper left corner of the window when displaying pinout
+ information. Both default to *100 mil*.
+
+`pinoutTextOffsetX (int)'
+`pinoutTextOffsetY (int)'
+ The resources determine the distance in mil between the drilling
+ hole of a pin to the location where its name is displayed in the
+ pinout window. They default to *X:50* and *Y:0*.
+
+`pinoutZoom (int)'
+ Sets the zoom factor for the pinout window according to the
+ formula: scale = 1:(2 power value). Its default value is *two*
+ which results in a *1:4* scale. See also, the command-line option
+ *-pz*.
+
+`printCommand (string)'
+ Default file for printouts. If the name starts with a '|' the
+ output is piped through the command. A %f is replaced by the
+ current filename. There is no default file or command.
+
+`raiseLogWindow (boolean)'
+ The log window will be raised when new messages arrive if this
+ resource is set *true*, the default.
+
+`ratCommand (string)'
+ Default command for reading a netlist. A %f is replaced by the
+ netlist filename. Its default value is "*cat %f*".
+
+`ratPath (string)'
+ Default path to look for netlist files. It's default value is "."
+
+`resetAfterElement (boolean)'
+ If set to *true*, all found connections will be reset before a new
+ element is scanned. This will produce long lists when scanning the
+ whole layout for connections. The resource is set to *false* by
+ default. The feature is only used while looking up connections of
+ all elements. See also, the command-line option *-reset, +reset*.
+
+`ringBellWhenFinished (boolean)'
+ Whether to ring the bell (the default) when a possibly lengthy
+ operation has finished or not. See also, the command-line option
+ *-ring, +ring*.
+
+`routeStyle (string)'
+ Default values for the menu of routing styles (seen in the sizes
+ menu). The string is a comma separated list of name, line
+ thickness, via diameter, and via drill size. e.g.
+ "Fat,50,100,40:Skinny,8,35,20:75Ohm,110,110,20" See also, the
+ command-line option *-rs* and *Sizes Menu*
+
+`rubberBandMode (boolean)'
+ Whether rubberband move and rotate (attached lines stretch like
+ rubberbands) is enabled (the default).
+
+`saveCommand (string)'
+ This command is used to save data to a layout file. The filename
+ may be indicated by placing `%f' in the string. It must read the
+ data from its standard input. The default command is:
+ cat - > %f
+ See also, the command-line option *-sfile*.
+
+`saveInTMP (boolean)'
+ Enabling this resource will save all data which would otherwise be
+ lost in a temporary file `/tmp/PCB.%i.save'. *%i* is replaced by
+ the process ID. As an example, loading a new layout when the old
+ one hasn't been saved would use this resource. See also, the
+ command-line option *-save, +save*.
+
+`saveLastCommand (boolean)'
+ Enables the saving of the last entered user command. The option is
+ *disabled* by default. See also, the command-line option *-s, +s*.
+
+`Shrink (dimension)'
+ Specifies the minimum overlap (touching) design rule in mils.
+
+`size (<width>x<height>)'
+ Defines the width and height of a new layout. The default is
+ *7000x5000*.
+
+`stipllePolygons (boolean)'
+ Determines whether to display polygons on the screen with a
+ stippled pattern. Stippling can create some amount of
+ transperency so that you can still (to some extent) see layers
+ beneath polygons. It defaults to False.
+
+`textScale (dimension)'
+ The font scaling in percent is defined by this resource. The
+ default is *100* percent.
+
+`useLogWindow (boolean)'
+ Several subroutines send messages to the user if an error occurs.
+ This resource determines if they appear inside the log window or

+ must be in the range [30..250] with at least 20 mil of copper.
+ The default thickness is *40 mil* and the default drilling hole is
+ *20 mil*.
+
+`volume (int)'
+ The value is passed to `XBell()' which sets the volume of the `X'
+ speaker. The value lies in the range -100..100 and it defaults to
+ the maximum volume of *100*.
+
+`warnColor (color)'
+ This resources defines the color to be used for drawing pins and
+ pads when a warning has been issued about them.

+
+Actions
+=======
+
+ All user accessible commands may be bound to almost any `X' event.
+Almost no default binding for commands is done in the binaries, so it
+is vital for the application that at least a system-wide application
+resource file exists. This file normally resides in the
+`X11/lib/app-defaults' directory and is called `Pcb'. The bindings to
+which the manual refers to are the ones as defined by the shipped
+resource file. Besides binding an action to an X11 event, you can also
+execute any action command using a ":" command (see *Note User
+Commands::).
+
+ Take special care about translations related to the functions keys
+and the pointer buttons because most of the window managers use them
+too. Change the file according to your hardware/software environment.
+You may have to replace all occurances of *baseTranslations* to
+*translations* if you use a `X11R4' server.
+
+ Passing *Object* as an argument to an action routine causes the
+object at the cursor location to be changed, removed or whatever. If
+more than one object is located at the crosshair position the smallest
+type is used. If there are two of the same type the newer one is taken.
+*SelectedObjects* will handle all selected and visible objects.
+
+`AddRats(AllRats|SelectedRats)'
+ Adds rat-lines to the layout using the loaded netlist file (see
+ the *:rn*, *Note User Commands::.). Rat lines are added on the
+ active layer using the current line thickness shown in the status
+ line. Only missing connectivity is added by the AddRats command
+ so if, for example, the layout is complete nothing will be added.
+ Rat lines are drawn on the screen with a stippled pattern to make
+ them easier to identify since they cannot appear in a completed
+ layout. The rat-lines are added in the minimum length
+ straight-line tree pattern (always ending on pins or pads) that
+ satisfies the missing connectivity in the circuit. If a SMD pad
+ is unreachable on the active layer, a warning will be issued about
+ it and the rat-line to that pad will not be generated. If
+ connections exist on the board which are not listed in the netlist
+ while AllRats are being added, warning messages will be issued and
+ the affected pins and pads will be drawn in a special *warnColor*
+ until the next *Notify()* event. If the entire layout agrees
+ completely with the net-list a message informs you that the layout
+ is complete and no rat-lines are added (since none are needed).
+ If *SelectedRats* is passed as the argument, only those missing
+ connections that might connect among the selected pins and pads
+ are drawn. Default:
+ None<Key>w: AddRats(AllRats)
+ !Shift<Key>w: AddRats(SelectedRats)
+ None<Key>o: DeleteRats(AllRats) AddRats(AllRats)
+ !Shift<Key>o: DeleteRats(SelectedRats) AddRats(SelectedRats)
+
+`Atomic(Save|Restore|Block|Close)'
+ Controls the undo grouping of sequences of actions. Before the
+ first action in a group, Atomic(Save) should be issued. After
+ each action that might be undoable, Atomic(Restore) should be
+ issued. Atomic(Block) concludes and save the undo grouping if
+ there was anything in the group to undo. Atomic(Close) concludes
+ and save the undo grouping even if nothing was actually done.
+ Thus it might produce an "empty" undo. This can be useful when
+ you want to use undo in a group of actions.
+
+`Bell([-100..100])'
+ Rings the bell of your display. If no value is passed the setting
+ of the resource *volume* will be used.
+
+`ChangeDrillSize(Object, value)'
+`ChangeDrillSize(SelectedPins|SelectedVias, value)'
+ This action routine changes the drilling hole of pins and vias.
+ If *value* starts with + or -, then it adds (or subtracts) *value*
+ from the current hole diameter, otherwise it sets the diameter to
+ the value. Default:
+ !Mod1<Key>s: Change2ndSize(Object, +5)
+ !Mod1 Shift<Key>s: Change2ndSize(Object, -5)
+
+`ChangeHole(Object|SelectedVias)'
+ This action routine converts a via to and from a hole. A hole is
+ a via that has no copper annulus. The drill size for the via
+ determines the hole diameter.
+ !Ctrl<Key>h: ChangeHole(Object)
+
+`ChangeName(Object)'
+`ChangeName(Layer|Layout)'
+ Changes the name of the visible object at the cursor location. A
+ text object doesn't have a name therefore the text string itself
+ is changed. The element name currently used for display is always
+ the one changed with this command. See
+ *Display(Description|NameOnPCB|Value)* for details. Passing
+ *Layer* changes the current layers name. Default:
+ None<Key>n: ChangeName(Object)
+
+`ChangeOctagon(Object|SelectElements|SelectedPins|SelectedVias|Selected)'
+ Toggles what shape the affected pin(s) or via(s) will be drawn
+ when they are not square. The shape will either be round or
+ octagonal. Default:
+ !Ctrl<Key>o: ChangeOctagon(Object)
+
+`ChangeSize(Object, value)'
+`ChangeSize(SelectedLines|SelectedPins|SelectedVias, value)'
+`ChangeSize(SelectedPads|SelectedTexts|SelectedNames, value)'
+`ChangeSize(SelectedElements, value)'
+ To change the size of an object you have to bind these action to
+ some `X' event (or use :ChangeSize(...)). If *value* begins with
+ a + or - then the value will be added (or subtracted) from the
+ current size, otherwise the size is set equal to *value*. Range
+ checking is done to insure that none of the maximum/minimums of
+ any size are violated. If *Object* is passed then a single object
+ at the cursor location is changed. If any of the *Selected*
+ arguments are passed then all selected and visible objects of that
+ type are changed. If the type being modified is an element, then
+ the thickness of the silkscreen lines defining the element is
+ changed. Default:
+ None<Key>s: ChangeSize(Object, +5)
+ !Shift<Key>s: ChangeSize(Object, -5)
+
+`ChangeSquare(Object|SelectedElements|SelectedPins)'
+ Toggles the setting of the square flag. The flag is used to
+ identify a certain pin, normally the first one, of circuits. It is
+ also used to make SMD pads have square ends.
+ None<Key>q: ChangeSquare(Object)
+
+`Command()'
+ Calling *Command()* pops up an input line at the bottom of the
+ window which allows you to enter commands. Including all action
+ commands! The dialog ends when *None<Key>Return* to confirm or
+ *None<Key>Escape* to abort is entered. Default:
+ <Key>colon: Command()
+
+`Connection(Find)'
+`Connection(ResetFoundLinesAndRectangles|ResetPinsViasAndPads|Reset)'
+ The *Connection()* action is used to mark all connections from one
+ pin, line or via to others. The *ResetFoundLinesAndRectangles,
+ ResetFoundPinsAndVias* and *Reset* arguments may be used to reset
+ all marked lines and rectangles, vias and pins or all of them. The
+ search starts with the pin or via at the cursor position. All
+ found objects are drawn with the color defined by the resource
+ *connectedColor*. See also,
+ *Display(Description|NameOnPCB|Value)*. Default:
+ !Shift<Key>c: Connection(Reset)
+ None<Key>f: Connection(Find)
+ !Shift<Key>f: Connection(Reset)
+
+`DeleteRats(AllRats|SelectedRats)'
+ This routine deletes either all rat-lines in the layout, or only
+ the selected and visible ones. Non-rat-lines and other layout
+ objects are unaffected. Default:
+ None<Key>e: DeleteRats(AllRats)
+ !Shift<Key>e: DeleteRats(SelectedRats)
+
+`Display(Description|NameOnPCB|Value)'
+`Display(Toggle45Degree|CycleClip)'
+`Display(Grid|ToggleGrid)'
+`Display(ToggleRubberBandMode)'
+`Display(Center|ClearAndRedraw|Redraw)'
+`Display(Pinout|PinOrPadName)'
+ This action routines handles some output related settings. It is
+ used to center the display around the cursor location and to
+ redraw the output area optionally after clearing the window.
+ Centering is done with respect to the *grid* setting. Displaying
+ the grid itself may be switched on and off by *Grid* but only if
+ the distance between two pixels exceeds 1_DISTANCE pixels. `Pcb'
+ is able to handle several labels of an element. One of them is a
+ description of the functionality (eg resistor), the second should
+ be a unique identifier (R1) whereas the last one is a value (100k).
+ The *Display()* action selects which of the names is displayed.
+ It also controls which name will be affected by the *ChangeName*
+ command. If *ToggleGrid* is passed, `Pcb' changes between relative
+ ('rel' in the statusline) and absolute grid (an 'abs' in the
+ statusline). Relative grid means the pointer position when the
+ command is issued is used as the grid origin; while (0,0) is used
+ in the absolute grid case. Passing *Pinout* displays the pinout
+ of the element at the current cursor location whereas
+ *PinOrPadName* toggles displaying of the pins or pads name under
+ the cursor. If none of them matches but the cursor is inside of an
+ element, the flags is toggled for all of its pins and pads. For
+ details about rubberbands see also the details about *Mode*.
+ Default:
+ None<Key>c: Display(Center)
+ None<Key>d: Display(PinOrPadName)
+ !Shift<Key>d: Display(Pinout)
+ None<Key>r: Display(ClearAndRedraw)
+ None<Key>.: Display(Toggle45Degree)
+ None<Key>/: Display(CycleClip)
+
+`DRC()'
+ Initiates design rule checking of the entire layout. Must be
+ repeated until no errors are found.
+
+`EditLayerGroups()'
+ Pops up a dialog box to edit the layergroup setting. The function
+ is also available from the *Objects* menu. There are no defaults.
+
+`Load(ElementToBuffer|Layout|LayoutToBuffer|Nelist)'
+ This routine pops up a fileselect box to load layout, element data,
+ or netlist. The passed filename for layout data is saved and may
+ be reused. *ElementToBuffer* and *LayoutToBuffer* load the data
+ into the current buffer. There are no defaults.
+
+`MarkCrosshair()'
+ This routine marks the current cursor location with an X, and then
+ the cursor display shows both absolute position and position
+ relative to the mark. If a mark is already present, this routine
+ removes it and stops displaying relative cursor coordinates.
+ Defaults:
+ !Ctrl<key>m: MarkCrosshair()
+
+`Mode(Copy|InsertPoint|Line|Move|None|PasteBuffer|Polygon|Thermal)'
+`Mode(Remove|Rectangle|RubberbandMove|Text|Via)'
+`Mode(Cycle)'
+`Mode(Notify)'
+`Mode(Save|Restore)'
+ Switches to a new mode of operation. The active mode is displayed
+ by a thick line around the matching mode selector button. Most of
+ the functionality of `Pcb' is implemented by selecting a mode and
+ calling *Mode(Notify)*. The arguments *Line*, *Polygon*,
+ *Rectangle*, *Text* and *Via* are used to create the appropriate
+ object whenever *Mode(Notify)* is called. Some of them, such as
+ *Polygon*, need more than one call for one object to be created.
+ *InsertPoint* adds points to existing polygons or lines. *Save*
+ and *Restore* are used to temporarily save the mode, switch to
+ another one, call *Mode(Notify)* and restore the saved one. Have a
+ look at the application resource file for examples. *Copy* and
+ *Move* modes are used to change an object's location and,
+ optionally, to create a new one. The first call of *Mode(Notify)*
+ attaches the object at the pointer location to the crosshair
+ whereas the second one drops it to the layout. The *rubberband*
+ version of move performs the move while overriding the current
+ rubberband mode. Passing *PasteBuffer* attaches the contents of
+ the currently selected buffer to the crosshair. Each call to
+ *Mode(Notify)* pastes this contents to the layout. *Mode(Cycle)*
+ cycles through the modes available in the mode-button pallete.
+ *Mode(None)* switches all modes off. Default:
+ <Key>Escape: Mode(None)
+ <Key>space: Mode(Cycle)
+ None<Key>BackSpace: Mode(Save) Mode(Remove) Mode(Notify) Mode(Restore)
+ None<Key>Delete: Mode(Save) Mode(Remove) Mode(Notify) Mode(Restore)
+ None<Key>F1: Mode(Via)
+ None<Key>F2: Mode(Line)
+ None<Key>F3: Mode(PasteBuffer)
+ None<Key>F4: Mode(Rectangle)
+ None<Key>F5: Mode(Text)
+ None<Key>F6: Mode(Polygon)
+ None<Key>F7: Mode(Thermal)
+ None<Key>F8: Mode(Arc)
+ None<Key>Insert: Mode(InsertPoint)
+ None<Key>[: Mode(Save) Mode(Move) Mode(Notify)
+ None<Key>]: Mode(Notify) Mode(Restore)
+ None<Btn1Down>: Mode(Notify)
+ !Shift Ctrl<Btn1Down>: Mode(Save) Mode(Remove) Mode(Notify) Mode(Restore)
+ None<Btn2Down>: Mode(Save) Mode(Move) Mode(Notify)
+ None<Btn2Up>: Mode(Notify) Mode(Restore)
+ !Mod1<Btn2Down>: Mode(Save) Mode(Copy) Mode(Notify)
+ !Mod1<Btn2Up>: Mode(Notify) Mode(Restore)
+ Shift Mod1<Btn2Down>: Mode(Save) Mode(RubberbandMove) Mode(Notify)
+
+`MovePointer(delta_x, delta_y)'
+ With this function it is possible to move the crosshair cursor by
+ using the cursor keys. The `X' server's pointer follows because
+ the necessary events are generated by `Pcb'. All movements are
+ performed with respect to the currently set grid value. Default:
+ None<Key>Up: MovePointer(0, -1)
+ !Shift<Key>Up: MovePointer(0, -10)
+ None<Key>Down: MovePointer(0, 1)
+ !Shift<Key>Down: MovePointer(0, 10)
+ None<Key>Right: MovePointer(1, 0)
+ !Shift<Key>Right: MovePointer(10, 0)
+ None<Key>Left: MovePointer(-1, 0)
+ !Shift<Key>Left: MovePointer(-10, 0)
+
+`MoveToCurrentLayer(Object|SelectedObjects)'
+ The function moves a single object at the crosshair location or
+ all selected objects to the current layer. Elements are not
+ moveable by this function. They have to be deleted and replaced
+ on the other side. If a line segment is moved and the movement
+ would result in a loss of connectivity to another segment then
+ via(s) are automatically added to maintain the connectivity.
+ None<Key>m: MoveToCurrentLayer(Object)
+ !Shift<Key>m: MoveToCurrentLayer(SelectedObjects)
+
+`New()'
+ Clear the current layout and starts a new one after entering its
+ name. Refer to the resource *backup* for more information. No
+ defaults.
+
+`PasteBuffer(AddSelected|Clear|1..5)'
+`PasteBuffer(Rotate, 1..3)'
+`PasteBuffer(Convert)'
+ This action routine controls and selects the pastebuffer as well
+ as all cut-and-paste operations. Passing a buffer number selects
+ one in of the range 1..5. The statusline is updated with the new
+ number. *Rotate* performs a number of 90 degree counter clockwise
+ rotations of the buffer contents. *AddSelected* as first argument
+ copies all selected and visible objects into the buffer. Passing
+ *Clear* removes all objects from the currently selected buffer.
+ *Convert* causes the contents of the buffer (lines, arc, vias) to
+ be converted into an element definition. Refer to *Note
+ Pastebuffer:: for examples. Default:
+ !Ctrl<Key>x: PasteBuffer(Clear) PasteBuffer(AddSelected)
+ Mode(PasteBuffer)
+ !Shift Ctrl<Key>x: PasteBuffer(Clear) PasteBuffer(AddSelected)
+ RemoveSelected() Mode(PasteBuffer)
+ !Mod1<Key>c: PasteBuffer(Clear) PasteBuffer(AddSelected)
+ !Mod1<key>x: PasteBuffer(Clear) PasteBuffer(AddSelected)
+ RemoveSelected()
+ !Shift<Key>1: PasteBuffer(1)
+ !Shift<Key>2: PasteBuffer(2)
+ !Shift<Key>3: PasteBuffer(3)
+ !Shift<Key>4: PasteBuffer(4)
+ !Shift<Key>5: PasteBuffer(5)
+ None<Key>F3: Mode(PasteBuffer)
+
+`Polygon((Close|PreviousPoint)'
+ Polygons need a special action routine to make life easier. Calling
+ *Polygon(PreviousPoint)* resets the newly entered corner to the
+ previous one. The Undo action will call Polygon(PreviousPoint)
+ when appropriate to do so. *Close* creates the final segment of
+ the polygon. This may fail if clipping to 45 degree lines is
+ switched on, in which case a warning is issued. Default:
+ None<Key>p: Polygon(Close)
+ !Shift<Key>p: Polygon(Close)
+
+`Print()'
+ Pops up a print control box that lets you select the output
+ device, scaling and many more options. Each run creates all files
+ that are supported by the selected device. These are mask files as
+ well as drilling files, silk screens and so on. The table shows
+ the filenames for all possible files:
+ POSIX (extention) 8.3 filename
+ ---------------------------------------------
+ *_componentmask.* cmsk.*
+ *_componentsilk.* cslk.*
+ *_soldermask.* smsk.*
+ *_soldersilk.* sslk.*
+ *_drill.* dril.*
+ *_groundplane.* gpl.*
+ *_group[1..8].* [..8].*
+ The output may be sent to a postprocessor by starting the filename
+ with the *pipe* `("|")' character. Any `"%f"' in a command is
+ replaced with the current filename. The function is available from
+ the *file* menu. There are no defaults.
+
+`Quit()'
+ Quits the application after confirming the operation. Default:
+ <Message>WM_PROTOCOLS: Quit()
+
+`Redo()'
+ This routine allows you to recover from the last undo command.
+ You might want to do this if you thought that undo was going to
+ revert something other than what it actually did (in case you are
+ confused about which operations are un-doable), or if you have
+ been backing up through a long undo list and over-shoot your
+ stopping point. Any change that is made since the undo in
+ question will trim the redo list. For example if you add ten
+ lines, then undo three of them you could use redo to put them
+ back, but if you move a line on the board before performing the
+ redo, you will lose the ability to "redo" the three "undone" lines.
+ Default:
+ !Shift<Key>r: Redo()
+
+`RemoveSelected()'
+ This routine removes all visible and selected objects. There are
+ no defaults.
+
+`Report(Object|DrillReport)'
+ This routine pops up a dialog box describing the various
+ characteristics of an object (or piece of an object such as a pad
+ or pin) in the layout at the cursor position, or a report about
+ all of the drill holes in the layout. There are no defaults.
+
+`RouteStyle(1|2|3|4)'
+ This routine copies the sizes corresponding to the numbered route
+ style into the active line thicknes, via diameter, and via drill
+ size. Defaults:
+ !Ctrl<Key>1: RouteStyle(1)
+ ...
+ !Ctrl<Key>4: RouteStyle(4)
+
+`Save(Layout|LayoutAs)'
+`Save(AllConnections|AllUnusedPins|ElementConnections)'
+ Passing *Layout* saves the layout using the file from which it was
+ loaded or, if it is a new layout, calls *Save(LayoutAs)* which
+ queries the user for a filename. The values: *AllConnections*,
+ *AllUnusedPins* and *ElementConnections* start a connection scan
+ and save all connections, all unused pins or the connections of a
+ single element to a file. There are no defaults.
+
+`Select(All|Block|Connection|ToggleObject)'
+`Select(ElementByName|ObjectByName|PadByName|PinByName)'
+`Select(TextByName|ViaByName)'
+ Toggles either the selection flag of the object at the crosshair
+ position (*ToggleObject*) or selects all visible objects, all
+ inside a rectangle or all objects which have been found during the
+ last connection scan. The *ByName* functions use a regular
+ expression search, always case insensitive, to select the objects.
+ Default:
+ None<Btn3Down>: Select(ToggleObject)
+ None<Btn3Down>,None<Btn3Motion>: See resource file - this is complex
+
+`SetValue(Grid|LineSize|TextScale|ViaDrillingHole|ViaSize|Zoom, value)'
+ Some internal values may be changed online by this function. The
+ first parameter specifies which data has to be changed. The other
+ one determines if the resource is set to the passed value, if
+ *value* is specified without sign, or increments/decrements if it
+ is specified with a plus or minus sign. The function doesn't
+ change any existing object only the initial values of new objects.
+ Use the *ChangeSize()* and *ChangeDrillSize()* to change existing
+ objects. Default:
+ None<Key>g: SetValue(Grid, +5)
+ !Shift<Key>g: SetValue(Grid, -5)
+ None<Key>l: SetValue(LineSize, +5)
+ !Shift<Key>l: SetValue(LineSize, -5)
+ None<Key>t: SetValue(TextScale, +10)
+ !Shift<Key>t: SetValue(TextScale, -10)
+ None<Key>v: SetValue(ViaSize, +5)
+ !Shift<Key>v: SetValue(ViaSize, -5)
+ !Mod1<Key>v: SetValue(ViaDrillingHole, +5)
+ !Mod1 Shift<Key>v: SetValue(ViaDrillingHole, -5)
+ None<Key>z: SetValue(Zoom, -1)
+ !Shift<Key>z: SetValue(Zoom, +1)
+
+`SwapSides()'
+ This routine changes the board side you are viewing. Default:
+ None<Key>Tab: SwapSides()
+
+`SwitchDrawingLayer(value)'
+ Makes layer numer 1..8 the current one. Default:
+ None<Key>1: SwitchDrawingLayer(1)
+ ...
+ None<Key>8: SwitchDrawingLayer(8)
+
+`ToggleHideName(Object|SelectedElements)'
+ Toggles whether the element's name is displayed or hidden. If it
+ is hidden you won't see it on the screen and it will not appear on
+ the silk layer when you print the layout.
+ None<Key>h: ToggleHideName(Object)
+ !Shift<Key>h: ToggleHideName(SelectedElements)
+
+`Undo()'
+`Undo(ClearList)'
+ The unlimited undo feature of `Pcb' allows you to recover from
+ most operations that materially affect you work. Calling *Undo()*
+ without any parameter recovers from the last (non-undo) operation.
+ *ClearList* is used to release the allocated memory. *ClearList*
+ is called whenever a new layout is started or loaded. See also
+ *Redo*. Default:
+ None<Key>u: Undo()
+ !Shift Ctrl<Key>u: Undo(ClearList)
+
+`Unselect(All|Block|Connection)'
+ Unselects all visible objects, all inside a rectangle or all
+ objects which have been found during the last connection scan.
+ Default:
+ !Shift <Btn3Down>: Mode(Save) Mode(None) Unselect(Block)
+ !Shift <Btn3Up>: Unselect(Block) Mode(Restore)

+Default Translations
+====================
+
+ This section covers some default translations of key and button
+events as defined in the shipped default application resource file.
+Most of them have already been listed in *Note Actions::. `Pcb' makes

+event.
+
+`None<Key>BackSpace:'
+
+`None<key>Delete:'
+`!Shift<Key>BackSpace:'
+`!Shift Ctrl<Btn1Down>:'
+ The object at the cursor location is removed by
+ *None<Key>BackSpace* or *Shift Ctrl<Btn1Down>* whereas
+ *Shift<Key>BackSpace* also removes all other objects that are
+ fully-connected to the one at the cursor location.
+
+`!Mod1 Ctrl<Key>Left:'
+`!Mod1 Ctrl<Key>Right:'
+`!Mod1 Ctrl<Key>Up:'
+`!Mod1 Ctrl<Key>Down:'
+ Scroll one page in one of the four directions.

+`None<Key>Left:, !Shift<Key>Left:'
+`None<Key>Right:, !Shift<Key>Right:'
+`None<Key>Up:, !Shift<Key>Up:'
+`None<Key>Down:, !Shift<Key>Down:'
+ Move crosshair either one or ten points in grid.
+
+`None<Key>Return:'
+ Finished user input, selects the 'default' button of dialogs.
+
+`None<Key>Escape:'
+ *Mode(Reset)*, aborts user input, selects the 'abort' button of
+ dialogs or resets all modes.
+
+`None<Btn2Down>, Btn2<Motion>, None<Btn2Up>:'
+`!Mod1<Btn2Down>, Btn2<Motion>, !Mod1<Btn2Up>:'
+ The first sequence moves the object or element name at the cursor
+ location. The second one copies the objects. Copying isn't
+ available for element names.

+File Formats
+************
+
+ All files used by `Pcb' are read from the standard output of a
+command or written to the standard input of one as plain seven bit
+`ASCII'. This makes it possible to use any editor to change the
+contents of a layout file. It is the only way for element or font
+description files to be created. To do so you'll need to study the
+example files `example/*' and `default_font' which are shipped with
+`Pcb'. For an overview refer to *Note Intro::.
+
+ The following sections provide the necessary information about the
+syntax of the files. Netlist files are not created by `Pcb', but it
+does use them. For information on the format of a netlist file see the
+*:rn*, *Note User Commands::. Rat lines are added on the current layer
+using the current The commands described allow you to add almost any
+additional functionality you may need. Examples are compressed read and
+write access as well as archives. The commands themselves are defined
+by the resources *elementCommand*, *fileCommand*, *fontCommand*,
+*libraryCommand*, *libraryContentsCommand* and *saveCommand*. Note
+that the commands are not saved along with the data. It is considered
+an advantage to have the layout file contain all necessary information,
+independent of any other files.
+
+ One thing common to all files is they may include comments, newlines,
+and carriage returns at any place except within quoted strings.

+ Points = "(" X Y ")"
+ Text = "Text(" X Y direction scale TextData Flags")"
+
+`PCBName'
+ is used to define the layout's name which is independent of its
+ filename. It is displayed in the lower left corner of the main
+ window.
+
+`GridData'
+ is optional and is used to save the grid setting and offset which
+ were set at the time the layout was saved.
+
+`CursorData'
+ also is an optional parameter to save the last cursor location and
+ zoom value. The real zoom factor is calculated by scale = 1:(2
+ power value).
+
+`PCBFlags'
+ determine how to draw lines and which name of the elements should
+ be displayed.
+ bit 4: do rubberband moves and rotates if set
+ bit 5: display description of elements if set
+ bit 6: display unique name of an element if set
+ bit 7: use absolute grid if set
+ bit 8: don't clip lines to 45 degrees
+
+`Groups'
+ Layergroups are saved by using this optional parameter. The only
+ way of changing them is to use an editor and alter the appropriate
+ line. The characters *c,s* idenify the component- and solder-side
+ for SMD objects.
+
+`Symbol'
+ See the description of font files in this chapter.
+
+`Via'
+ Vias are always connected to all layers which also means vias are
+ one logical level ahead of layers. Vias are defined by position,
+ size, name and by some flags.
+ bit 0: always clear
+ bit 1: always set
+ bit 2: set if via was found during a connection search
+ bit 4: set if via is a hole (has no copper annulus)
+ bit 5: display the vias name
+ bit 6: via has been selected
+ bit 12: set if via has octagonal shape
+ Other bits have special meaning and should not be changed
+ by the user. See const.h for more information
+
+`Element'
+ See the description of element files in this chapter.
+
+`Layer'
+ A layer is the central object from the user's point of view. It
+ holds all connections and all text objects. Up to 8 may be used
+ individually. Its number, starting with one, and its name are
+ read as arguments.
+
+ `Line'
+ All lines are identified by their start and endpoints
+ together with their thickness and some flags. They have to
+ fit a 45 degree scheme.
+ bit 2: set if line was found during a connection search
+ bit 4: line is a rat-line
+ bit 6: line has been selected
+
+ `Polygon'
+ used to fill a larger area with `copper'. The coordinates
+ specify the corners. The flags are:
+ bit 2: set if polygon was found during a connection search
+ bit 4: polygon is a 1.5 style polygon that automatically clears pins
+ bit 6: polygon has been selected
+
+ `Text'
+ You may use text objects to add information to your board. An
+ example would be naming a connector or marking pin one of it.
+ The position marks the lower left corner of the string which
+ is also a fixpoint for rotations. Text directions are
+ independent to those of lines. They are counted from zero to
+ three with a meaning of zero to 270 degree rotations
+ counter-clockwise. The scaling value is a positive integer
+ which determines a zoom factor in percent.
+ bit 6: the text has been selected
+ bit 7: the text is on the solder (back) side of the board
+ bit 10: the text is on the silkscreen layer
+

+
+Element File Format
+===================
+
+ Element files are used to describe one component which then may be
+used several times within one or more layouts. You will normally split
+the file into two parts, one for the pinout and one for the package
+description. Using `m4' allows you to define pin names as macros in
+one file and include a package description file which evaluates the
+macros. See the resource *elementCommand* for more information. The
+pins (and pads) must appear in squential order in the element file (new
+in 1.5) so that pin 1 must be the first PIN(...) in the file.
+
+ Doing things this way makes it possible to use one package file for
+several different circuits. See the sample files `dil*'.
+
+ The lowest x and y coordinates of all subobjects of an element are
+used as an attachment point for the crosshair cursor of the main window.
+
+ File = {Element}...
+ Element = "Element(" Flags Description LayoutName Value \
+ TextX TextY direction scale TextFlags")"
+ "(" {ElementData}... [Mark] ")"
+ ElementData = {ElementLine | Pad | Pin | ElementArc }...
+ ElementArc = "ElementArc(" X Y Width Height
+ StartAngle DeltaAngle Thickness ")"
+ ElementLine = "ElementLine(" X1 Y1 X2 Y2 Thickness ")"
+ Mark = "Mark(" X Y ")"
+ Pad = "Pad(" X1 Y1 X2 Y2 Thickness Name PinNumber Flags ")"
+ Pin = "Pin(" X Y Thickness DrillingHole Name PinNumber Flags ")"
+
+`Element'
+ Objects of type element are determined by flags, some names, a
+ canonical and a layout name as well as a value. Additional fields
+ are text position, their direction counted from zero to three (n *
+ 90 degrees counter-clockwise) and element data.
+
+ `Flags'
+ The flag field determines the state of an element. The bit
+ values are:
+ bit 4: the element name is hidden
+ bit 6: element has been selected
+ bit 7: element is located on the solder side
+
+ `TextFlags'
+ `scale'
+ `direction'
+ See the description of text object earlier in this chapter.
+
+ `ElementLine'
+ A line is defined by its start and end points and by its
+ size, or width.
+
+ `ElementArc'
+ Defines an arc by its center, width, height, startangle, its
+ length in degrees and its size. Remember the y axis on the
+ screen grows downwards.
+
+ `Mark'
+ is just a hint to make positioning easier. The crosshair will
+ be positioned here. Its center is passed as the two arguments.
+
+ `Pad'
+ A pad is very similar to a line except it may not be
+ disconnected from its element and it has an associated name.
+ Is is defined by two end point position, size, name and by
+ some flags.
+ bit 2: set if pad was found during a connection search
+ bit 5: display the pads name
+ bit 6: pad has been selected
+ bit 7: pad is located on the solder side
+
+ `Pin'
+ A pin is very similar to a via except it may not be
+ disconnected from its element.
+ bit 0: always set
+ bit 1: always clear
+ bit 2: set if pin was found during a connection search
+ bit 3: set if pin is only a mounting hole (no copper annulus)
+ bit 5: display the pins name
+ bit 6: pin has been selected
+ bit 8: pin is drawn as a square
+ bit 12: set if pin is drawn with an octagonal shape

+
+Font File Format
+================
+
+ A number of user defined symbols are called a font. There is only
+one per layout. All symbols are made of lines. See the file
+`default_font' as an example.
+
+ The lowest x and y coordinates of all lines of a font are
+transformed to (0,0).
+
+ File = Font
+ Font = {FontData}...
+ FontData = {Symbol}...
+ Symbol = "Symbol(" SymbolID FontPosition ")"
+ "(" {SymbolData}... ")"
+ SymbolData = {SymbolLine}...
+
+`Symbol'
+ The two arguments are the `ASCII' code of the symbol and its
+ distance to the next symbol. Undefined symbols are drawn as filled
+ rectangles. The `ASCII' code may be passed as a character
+ constant or as a hexadecimal value.
+
+ `SymbolLine'
+ The symbol data itself is made up of several entries of type
+ *SymbolLine*.
+
+
+File: pcb.info, Node: Library Contents File, Next: Library File, Prev: Font File, Up: File Formats
+
+Library Contents File Format
+============================
+
+ There is nothing like a special library format. The ones that have
+been introduced in 1.4.1 just use some nice (and time consuming)
+fetures of GNU `m4'. The only predefined format is the one of the
+contents file which is read during startup. It is made up of two basic
+line types:
+
+ menu entry = "TYPE="name
+ contents line = template":"package":"value":"description
+ name = String
+ template = String
+ package = String
+ value = String
+ description = String
+ String = <anything except ":", "\n" and "\r">
+
+ No leading whitespaces or comments are allowed in this file. If you
+need either one, define a command that removes them before loading.
+Have a look to the *libraryContentsCommand* resource.
+
+ The menu entry will appear in the selection menu at the top and of
+the library window.
+
+
+File: pcb.info, Node: Library File, Prev: Library Contents File, Up: File Formats
+
+Library File Format
+===================
+
+ This section provides an overview about the existing `m4' definitions
+of the elements. There are basically two different types of files. One
+to define element specific data like the pinout, package and so on, the
+other to define the values. For example the static RAM circuits 43256
+and 62256 are very similar. They therefore share a common definition in
+the macro file but are defined with two different value labels.
+
+ The macro file entry:
+ define(`Description_43256_dil', `SRAM 32Kx8')
+ define(`Param1_43256_dil', 28)
+ define(`Param2_43256_dil', 600)
+ define(`PinList_43256_dil', ``pin1', `pin2', ...')
+
+ And the list file:
+ 43256_dil:N:43256:62256
+
+ The macro must define a description, the pin list and up to two
+additional parameters that are passed to the package definitions. The
+first one is the number of pins whereas the second one defines for
+example the width of a package.
+
+ It is very important to select a unique identifier for each macro. In
+the example this would be *43256_dil* which is also the templates name.
+It is required by some low-level macros that *Description_, Param1_,
+Param2_* and *PinList_* are prepended.
+
+ The list file uses a syntax:
+ template:package:value[:more values]
+
+ This means that the shown example will create two element entries
+with the sam package and pinout but with different names.
+
+ A number of packages are defined in `common.m4'. Included are:
+
+ DIL packages with suffix D, DW, J, JD, JG, N, NT, P
+ PLCC
+ TO3
+ generic connectors
+ DIN 41.612 connectors
+ zick-zack (SD suffix)
+ 15 pin multiwatt
+
+ If you are going to start your own library please take care about
+`m4' functions. Be aware of quoting and so on and, most important check
+your additional entry by calling the macro:
+
+ CreateObject(`template', `value', `package suffix')
+
+ If quoting is incorrect an endless loop may occur (broken by a
+out-of-memory message).
+
+ The scripts in the `lib' directory handle the creation of libraries
+as well as of their contents files. Querying is also supported.
+
+ I know quite well that this description of the library
+implementation is not what some out there expect. But in my opinion
+it's much more useful to look at the comments and follow the macros
+step by step.

+Editing config.h
+----------------
+
+ Most `X11' related options are automatically covered by `imake'
+which is called from `xmkmf'. The ones special to `Pcb' have to be
+edited in `config.h'. In order of appearance:
+
+`INFOLIBDIR'
+ must be set to the directory where your GNU info files are located.
+
+`/usr/X11R6/lib/X11/pcb'
+ is the path of a directory where the font files will be installed.
+
+`DEFAULTFONT'
+ the name of the default font file.
+
+`DEFAULTLIBRARY'
+ the name of the default library.
+
+`gm4'
+ the name of GNUs m4 version.
+
+`Mod1'
+ If your window manager has already bound *Mod1* together with some
+ function keys you may want to change this setting. This is true
+ for HP-VUE.
+
+`EXTRA_INCLUDES'
+ Some systems do not have the Athena Widget include files in their
+ normal place as configured by `X11's config files. Define this as
+ follows:
+ EXTRA_INCLUDES = -I/usr/openwin/share/include
+ This is probably true for Suns which use `OpenWindows'.
+
+`PATCHES'
+ This symbol is passed to the compiler. Use it to define additional
+ compiler flags. Add the *-DNEED_STRDUP* flag, if your system does
+ not have a strdup() library function.
+
+`HAS_REGEX'
+ Set to *-DHAS_REGEX* if your system supports regular expressions.
+ This enables the actions *Select(*ByName)*.
+
+`EXITCALL'
+ The symbol *EXITCALL* should be defined according to the *call on
+ exit* functions supported by your system. There are three choices:
+ EXITCALL = -DHAS_ATEXIT if atexit() is supported (SYSV)
+ EXITCALL = -DHAS_ON_EXIT if on_exit() and no atexit() is supported
+ EXITCALL = if none of them is supported
+ Please check your manpages for details.
+
+`SYS_LIBRARIES'
+ This symbol is used to pass additional libraries to the linker.
+ The only additional libraries which are used are the math and lex
+ library.
+
+ If you have to make system dependent changes please include them
+into a *#ifdef Architecture* ... *#endif* construct and mail a copy to
+the author (Thomas.Nau@rz.uni-ulm.de).
+
+ Now run `xmkmf -a' which creates the `Makefiles' and runs `make
+depend'. This should finish without any problems except some systems
+which complain about missing include files. Don't worry about any such
+warnings at this time, the package should compile without any problems.
+
+
+File: pcb.info, Node: manuals, Next: make, Prev: config.h, Up: compiling
+
+Manuals
+-------
+
+ After `xmkmf -a' has created the new `Makefile' you are able to
+create the manpages, the application resource, the info file, the `TeX'
+output and a reference card by executing
+ (cd doc; make)
+ (cd src; make Pcb.ad)
+ You'll need `TeX', `texindex' and, if you want `PostScript', `dvips'
+to build the manuals. Preformatted documentation for the default
+configuration may be found in the `./doc.ps' directory. A simple
+*make* builds everything. Generate a printed copy to make your life
+easier. `TeX-3.0' failed, `TeX-3.14' worked just fine.
+
+
+File: pcb.info, Node: make, Prev: manuals, Up: compiling
+
+Compiling the Package
+---------------------
+
+ After reaching this point, it is time for `make'. It should build
+everything without any errors. If it doesn't refer to *Note problems::.
+
+ You have to be root to install the package or at least a user with
+the appropriate priveleges in some `X11' directories. Set the umask to
+*022* or else some files will not be found because the directory isn't
+world readable.
+
+ If you do not have the appropriate permissions you should run
+`./pcbtest.sh' in the `src' directory to run `Pcb' from the
+installation directory.
+
+ `make install' and `make install.man' install the program, the
+fonts, the application default resource file, all element and package
+data as well as the manpage into the `X11' directories. `make
+install.info' does the same for the `GNU' info file.
+
+
+File: pcb.info, Node: problems, Prev: compiling, Up: Installation
+
+Troubleshooting
+===============
+
+ There are some known problems. Most of them are related to missing
+parts of a standard `X11' distribution. Some others are caused by third
+party applications such as `X' servers. To make this list more complete
+please mail your problems and, if available, solutions to the author.
+The mail address may be found at the beginning of this chapter. In any
+case, read *Note X11::.
+
+ By the way, you `MUST HAVE AN ANSI COMPILER' to make `Pcb' work.
+
+ If the shell script `create_sed_script.sh' fails with an error of
+`awk' check your system for `nawk' or get the `GNU gawk'. See the
+script for details.
+
+ Another source of problems are older versions of `flex' and `bison'.
+`Pcb' definitely works with `flex-2.4.7' and `bison-1.22' or later. The
+problems will result in a *syntax error* while parsing files. You will
+have to add *-lfl* to the SYS_LIBRARIES identifier in `Imakefile'. See
+also, *Note FreeBSD::.
+
+ The following list gives you just an idea because I'm not able to
+test all `Pcb' releases on all platforms.
+
+* Menu:
+
+* HP:: Hewlett-Packard series 700 and 800 running HP-UX 10.*
+* Sun:: Sun, Solaris 2.5
+* SGI:: SGI, IRIX 5.3 and 6.*
+* DEC Alpha:: DEC Alpha, DEC UNIX 3.2c and 4.0
+* SCO:: SCO Unix ODT 3.0, PC hardware
+* Linux:: Linux 0.99pl14 and later
+* FreeBSD:: FreeBSD, NetBSD ...

+File: pcb.info, Node: HP, Next: Sun, Up: problems
+
+HP Series 700 and 800
+---------------------
+
+ You have to install several `X11' tools (`imake') and include files
+or, better, install a complete `X11R5' release. Hewlett-Packard doesn't
+support the Athena Widgets. So the header files and libraries are
+missing from the application media, but they are available as a patch.
+They also do not ship the `ANSI' compiler with the normal operating
+system release so you have to buy one or use `GCC'. Some of the tools
+are available as patches.
+
+ In addition, `Pcb' has been successfully tested on these platforms
+with `HPUX 9.*, 10.*' running self-compiled `X11R5'.
+
+
+File: pcb.info, Node: Sun, Next: SGI, Prev: HP, Up: problems
+
+Sun SPARC architecture
+----------------------
+
+ There are no known problems with Sun machines if they use `X11R5'
+instead of `OpenWindows'. `Pcb' compiled successfully with all kinds of
+SPARCstations `Solaris-2.[345]'.
+
+ For problems with `OpenWindows' refer to *Note X11::.
+
+ If `xmkmf' is missing, try
+ /usr/openwin/bin/imake -DUseInstalled -I/usr/openwin/lib/config
+ make Makefile
+ make includes
+ make depend
+ instead. I got it compiled but the linker complained about missing
+symbols. The problem may be related to the mixed `OpenWindows' -
+`X11R5' environment which is installed on the test machine. Anyway the
+code was executable and I haven't got a core yet.
+
+
+File: pcb.info, Node: SGI, Next: DEC Alpha, Prev: Sun, Up: problems
+
+Silicon Graphics
+----------------
+
+ `Pcb' has been tested on some boxes running either `IRIX-4.0.5' or
+`IRIX-5.3'. The former one uses a `X11R4' server. There are no
+problems except some additionally needed compiler flags. For known
+problems with `X11R4', see *Note X11::. Check `Imakefile', too.
+
+
+File: pcb.info, Node: DEC Alpha, Next: SCO, Prev: SGI, Up: problems
+
+DEC Alpha
+---------
+
+ `Pcb' compiled and runs without problems on `DEC UNIX V3.2c' if you
+do the following instead of calling `xmkmf -a':
+ xmkmf
+ make Makefiles
+ make includes
+ make depend
+

+ Since the `X11' version of `Pcb' has been developed on a Linux
+system here are no known problems.
+
+
+File: pcb.info, Node: FreeBSD, Next: X11, Prev: Linux, Up: problems
+
+FreeBSD and NetBSD
+------------------
+
+ If `Pcb' complains about syntax errors even in the demo files get
+rid of your `lex' and `yacc' implementation. Replace them by `GNU flex'
+and `bison'. Don't forget to change the SYS_LIBRARIES in `Imakefile'
+from *-ll* to *-lfl*. You also need to define:
+ YACC = bison -y
+ LEX = flex
+
+
+File: pcb.info, Node: X11, Next: TeX and Manuals, Prev: FreeBSD, Up: problems
+
+Problems related to X11
+-----------------------
+
+ There are a some problems related to `X11R4' or systems derived from
+`X11' such as `OpenWindows'. *Note Sun::. You at least have to change
+all occurances of *baseTranslations* in the resource files to
+*translations* if you are using a `X11R4' server. Look at the `X11R5'
+*Intrinsics* manual for details.
+
+ The panner widget (print dialog box) appears only in release `X11R5'
+and later. It really simplifies adjusting the offsets. With earlier
+releases the printout will always appear in the center of the page.
+
+ You may have some problems in a mixed `X11-OpenWindows' environment.
+If you want to try it anyway you have to add an additional path for
+include files and define another symbol in `Imakefile',
+ EXTRA_INCLUDES = -I/usr/openwin/include
+
+ `Pcb' has been tested successfully with `X11R6' under Linux 1.1.59
+and later.
+
+
+File: pcb.info, Node: TeX and Manuals, Prev: X11, Up: problems
+
+Problems related to TeX
+-----------------------
+
+ If your `TeX' installation complains about a missing `texinfo.tex'
+file copy the one included in this release (directory `doc' to your
+`TeX' macro directory. Note, there are probably newer versions of this
+file available from some FTP sites. `TeX-3.0' failed, `TeX-3.14'
+worked just fine. Check our FTP server *ftp.uni-ulm.de* for
+ready-to-print versions of the manuals.
