WRKSRC= ${WRKDIR}
This is much cleaner, much more indicative of what happens, and removes
another of the negative definitions (NO_.* = value).
|
|
|
|
Changes include:
- add the ability to specify gain in terms of voltage gain _or_ power gain
- add input/output resistance keywords
- add defaults keyword to allow users to change program defaults on the fly
- the cascade-mode for emacs now works for fontlock
- add voltage output levels in addition to the power levels
- add a verbose style comment (ie, one which gets copied to the output file
instead of being simply ignored).
- new homepage and master ftp site.
The previous version had no known bugs. Hopefully this one won't either.

to ${X11BASE} in the header and library search paths into references to
${LOCALBASE}/share/x11-links. These packages should now be strongly-
buildlinked regardless of whether xpkgwedge is installed.
Changes well-tested on NetBSD-1.5X/i386 with and without xpkgwedge and
lightly-tested on NetBSD-1.5.1/alpha without xpkgwedge.

bsd.prefs.mk so that it is actually used. Where possible, include
xaw.buildlink.mk instead of setting USE_XAW, and use LIBXAW where needed.

* The Big Change: VVP
Past versions of Icarus Verilog performed simulation by compiling the
Verilog design to intermediate C++ code, then in turn compiling that
C++ (usually with G++) to a binary executable. This program was then
executed to actually run the simulation.
The 0.5 compiler, however, uses a custom internal language called
"vvp." The vvp code generator writes a program in the vvp language
that the vvp interpreter executes. This gets runtime performance
similar to the older vvm method, but compile times are much faster.
The result of this change is that there is a new program, ``vvp'',
that is installed with the existing ``iverilog'' compiler. This
program actually executes the simulation generated by the vvp code
generator.
There are manual pages for the iverilog command and the new vvp
command, as well as a QUICK_START document to help you run your first
simulation.
* What Else Is New
The compiler itself is now a lot more robust. While it still does not
compile and understand the entire IEEE1364 standard, the compiler is
less likely to crash on bad input, gives better error messages, and
has generally been cleaned up.

ACS 0.29 release notes (06/30/2001)
The primary effort has been to implement IBIS, which is still not
done. The changes here are mostly infrastructure changes needed to
support IBIS.
New features:
1. "Fit" function has choice of fit order and extrapolation. You can
have order 0, 1, 2, or 3.
2. "Posy" has even and odd options, to determine what happens in the
negative region.
3. Modelgen improvements. It now is useful for the whole device,
sometimes. It now handles probes and the device side of the model.
The diode uses it completely. There are still a few missing features
needed for the MOSFET and BJT.
4. Spice-3 compatible semiconductor resistor and capacitor.
5. "Table" model statement.
Improvements, bug fixes, etc.
1. Option "numdgt" really works.
2. Better error messages from modelgen.
3. Code changes for optimization of commons. This should reduce
memory use, sometimes, by sharing commons. Common sharing is still
not fully implemented.
4. Fix two bugs that sometimes caused problems after a "modify" or on
a "fault".
5. Better handling of "vmin" and "vmax". It should be much less
likely that limiting causes convergence to a nonsense result.
Some things that are still partially implemented:
1. Internal element: non-quasi-static poly-capacitor.
2. BSIM models, charge effects, "alpha0" parameter. (computed then ignored)

RELEASE NOTE FOR ICARUS VERILOG 20010630
I've done some cleanup of the mingw port of Icarus Verilog. I've also
added instructions for how to build Icarus Verilog under mingw. I'm
working on making that the preferred way to support Windows, and when
I make the 0.5 release I will make Windows binaries this way. Anyhow,
feedback on the build instructions and the build results using the
instructions in mingw.txt are welcome.
I've make "vvp" the default target type. The older vvm behavior is
available with the "-tvvm" flag to iverilog, but I would rather be
told about (and fix) bugs in the vvp code generator and run time.
I've added support for the (unsigned) right shift operator. The left
shift has been working for a while now, but right shift somehow
slipped through the cracks. The shift operators still don't quite work
in structural contexts, but they should show up sometime next week.
I've finally got VCD output working properly with vvp. It may even be
better then with vvm, although some internal symbols are still generated.
A few odd bugs have been fixed, including a code generation error for
xnf, and error checking of user defined function parameters.

adapt by moving CPPFLAGS settings to top-level, and removing explicit
inclusion of CPPFLAGS into MAKE_ENV and CONFIGURE_ENV.

CXXFLAGS, and LDFLAGS by the buildlink.mk files so remove the extra
definitions to add them from the package Makefiles. As advised by the
bsd.buildlink.mk file, also ensure that the buildlink.mk files are
included prior to defining any package-specific CFLAGS/LDFLAGS to ensure
that the buildlink directories are at the head of the compiler search
paths.
|
|
targets as the buildlink.mk files now add the dependency automatically.
Remove any NO_CONFIGURE definitions as they seem to be useless.

many changes since the last snapshot. Mostly they involve expanded
VVP support. The VVP target now passes >200 of the tests from the
test suite. While not as complete as the VVM target, VVP is getting

increase in version number. From the XCircuit homepage:
Note that the March 28, 2001 version corrects a bug due to
dubious C syntax causing segmentation violations when xcircuit
was compiled without the debug option.
C Trivia question:
What does "x[a] = x[--a]" do?
Answer A: "x[a] = x[a - 1]; a--"
Answer B: "a--; x[a] = x[a]"
Answer C: either A or B, depending on your OS, compiler version,
and/or debug or optimizer switch.

Changes since the last packaged snapshot from the authors announcements:
Icarus Verilog snapshot 20010422
--------------------------------
I've integrated a bunch of UDP patches from Stephan Boettcher. These
go to the core of ivl, so if you use Icarus Verilog with UDPs, you
might want to give this a test for us.
Stephan has also added some ivl_target support for UDP devices. This is a
prerequisite to vvp support for UDP devices.
Some of you have been beating me over the head about disable, so the
vvp target now supports disable. It only works in certain very constrained
situations, but the idea is there and the more common cases are simply a
matter of getting around to them. I actually could use more examples of
the use of disable for the test suite.
In the process, I have settled on the interaction of threads and scopes,
and changed the %fork syntax to match. See the README.txt and opcodes.txt
file for details. The implementation of %end and %join simplified in
the process.
The vvp-tgt code generator supports a few more gate types. New gate
types are pretty easy to add, it's just boring grunt work. That's why
they've been popping up slowly.
I've also got certain behavioral shifts working. Only constant shifts,
so far, but this covers a pretty large percentage of the real world
uses of shift, I think.
I fixed a few specify block parse problems, so it should ignore
even more complex specify blocks now:-) One of these days I really will
properly support specify blocks.
PROGRESS
I was hoping to get vvp up to a similar level as vvm by the end of
April, but that doesn't look like it's going to happen. I'm up to 182
tests passed, compared to 318 of Icarus Verilog/vvm, so I have a ways
to go yet. I see no real point to making a release until I get up to
300 or so tests passed. That is the goal for 0.5 release.
But of course if vvp is enough for you, then it is soooo much faster
then vvm.
Icarus Verilog 20010415 Snapshot
--------------------------------
As with all the most recent snapshots, this is almost entirely progress
with the vvp code generator and simulation engine. I'm up to 159 tests
passed in the test suite, so I'm getting there. But there's still plenty
to go.
I also fixed what appeared to be a minor problem with elaboration of ?:
expressions in continuous assignments. The code was actually fine, it
was a spurious assert. This fix affects vvm as well.
Icarus Verilog/vvp now support <= statemements with internal delays.
That is, "foo <= #10 bar;" should work properly, and there are tests
in the suite that prove it. This is a pretty common syntax, so this
should help a lot of folks.
I also fixed a bug in the code generator that would cause it to put a
constant bit as a destination for the bitwise boolean operators. This
caused run-time asserts.
The event or support in vvp has been extended to now support arbitrary
width, so now you can for example wit for any changes in a 32bit reg.
This handles most of the likely cases, so @ statements should now be
pretty generally functional.
The handling of run-time threads has been revamped in preparation for
support of the disable statement. It also plugs a memory leak where
fork/join and task/function calls are invoked. And this version should
also clean up all those tiny initial foo=bar threads that all programs
seem to have. Threads that are done are now freed, along with their
memory, hopefully reducing the runtime memory footprint.
That's pretty much it this time 'round. Working with threads took some
time, so the progress isn't as flashy as it sometimes is.
There is still lots to do with vvp before 0.5, but I would appreciate
any feedback you can offer. It's complete enough already that I'm able
to accept bug reports on it, even if it turns out to be a "not supported
yet" type of thing. At this point, I'd be curious to know what hangups
are preventing its regular use.

|
* Control Panel
- The Control Panel now has a "Tree View" which provides an
overview over all areas of EAGLE, like Libraries, User Language
Programs, Projects etc. The Control Panel's tree view supports
"Drag&Drop" to copy or move files and directories.
- Objects in the tree view have a context menu that can be
accessed by pressing the right mouse button.
- The menu option "Save project as..." is no longer available.
- New projects can now be created via the context menu in the
"Projects" tree item, or by selecting "File/New/Project" from
the Control Panel.
- The path settings in "Options/Directories" can now use the special
names "$HOME" and "$EAGLEDIR" to access the user's home directory
or the EAGLE installation directory, respectively.
- The new "Auto backup" feature will automatically save any modified
drawing into a safety backup file after a certain time.
* New Project Structure
- The names of files that are under the current project directory
are no longer written as absolute paths into the 'eagle.epf' file,
but rather relative to the project directory. This allows for
complete project directories to be easily copied or renamed.
- A project is now held in a subdirectory that contains a file
named 'eagle.epf' (which stores the location and settings of open
windows).
* User Interface
- The textual command menu can now be configured to display
aliased command buttons as well as submenus (see HELP MENU for
details).
- Changes made in the "Options/User interface" dialog now take effect
immediately for open editor windows.
- The cursor inside a layout or schematic editor window can now be
set to a "large" crosshair cursor (see "Options/User interface").
- The "Delete" icon was changed from a pencil with an eraser to
an 'X'.
- The "Split" icon was changed to better indicate what will happen.
* Keyboard and mouse control
- Alt-0 no longer popups up the window list, but leads directly to
the Control Panel.
- Pressing the Ctrl key while moving the mouse now scrolls the draw
window in any direction.
- The mouse wheel now zooms in and out in editor windows (zoom
factor can be adjusted in "Options/User interface/Mouse wheel
zoom", a value of '0' disables this feature and the sign of this
factor defines the direction of the zoom operation).
* Screen display
- The default for "minimum visible text size" has been changed to 3.
- The display mode parameter FAST has been dropped.
- By default the zoom factor in editor windows is limited so that
the resulting virtual drawing area does not exceed the 16-bit
coordinate range. This is necessary to avoid problems with
graphics drivers that are not 32-bit proof. If the graphics
driver on a particular system can handle coordinates that
exceeed the 16-bit range, "Options/User interface/Limit zoom
factor" can be switched off allow larger zoom factors.
* Design Rules
- EAGLE now supports a full set of Design Rules that are stored
inside the board file (and can also be saved to disk files).
Both the Design Rule Check and the Autorouter will use the
same set of rules.
- Newly created boards take their design rules from the file
'default.dru', which is searched for in the first directory
listed in the "Options/Directories/Design rules" path.
- Cream mask values are now measured "inwards" and thus have a
positive sign.
- The parameters AnnulusConduct and ThermalConduct are no longer
available. There are now checkboxes in the Design Rules dialog's
"Supply" tab that define whether a Thermal or Annulus symbol
shall have a "Restring" or not.
* Net Classes
- Nets and Signals now have a new parameter called "Net Class".
* Polygons
- When calculating polygons, the minimum distances defined in
the design rules and net classes will be taken into account.
* Design Rule Check
- The DRC now runs a lot faster.
- Progress is now displayed in a progress bar.
- Polygons from different signals with the same 'rank' are checked
against each other.
- The 'overlap' and 'minimum distance' check are no longer separate
checks.
- The DRC no longer checks an individual signal against everything
else. The newly introduced "Net Classes" can be used to do this.
- The rectangle for a selective DRC can now be defined with
"click&drag" (just as in the WINDOW command).
- Holes are no longer checked in the "Grid" check (only pads, vias,
smds and wires in signal layers are checked).
- Any objects in signal layers within a package are now checked
against each other.
* Long strings
- All names, values and texts can now be of any length.
- The User Language constants regarding name lengths still exist,
but the program uses these constants only for formatted output as
in the EXPORT command. They are still present for compatibility
only.
- There is no more limit to the number of members in a bus (bus
index values are limited to 0..511).
- Bus member names can now contain any characters, except
':', ',', '[', ']' and blanks.
* Wire styles
- Wires now have a new parameter 'Style', which can be set to one
of the following values:
Continuous _______________ (default)
LongDash ___ ___ ___ ___
ShortDash _ _ _ _ _ _ _ _
DashDot ___ . ___ . ___
- The variable for setting the bend type of a wire has been renamed
from Wires_Style to Wire_Bend to avoid confusing the two
parameters.
* Text fonts
- Texts can now have three different fonts: 'Vector' the program's
internal vector font (as used in previous versions)
'Proportional' a proportional pixel font (usually 'Helvetica')
'Fixed' a monospaced pixel font (usually 'Courier')
- When updating drawings from older versions, all texts are
converted to 'Proportional' font, except for those in layers
Top...Bottom, tRestrict and bRestrict, since these texts probably
need to be subtracted from signal polygons, which only works with
the 'Vector' font.
- The program makes great efforts to output texts with fonts other
than 'Vector' as good as possible. However, since the actual font
is drawn by the system's graphics interface, 'Proportional' and
'Fixed' fonts may be output with different sizes and/or lengths.
* Pads and Vias
- The diameter of pads and vias is now derived from the drill
diameter using the Design Rules (the pad and via diameter '0' is
now allowed and results in a diameter that is derived from the
current design rules). If a pad is defined with a diameter that
exceeds the one that would result from the current design rules,
the larger diameter is taken. The default value for the diameter
of newly created pads and vias is now '0' to allow the Design
Rules to define the actual diameters.
- Pads can have different shapes on Top and Bottom (they will always
be 'round' on the inner layers).
- The via shape now only applies to the outer layers (they will
always be 'round' on the inner layers).
- The diameter of pads with shape X/YLongOct now defines the
smaller side of the pad (formerly the wider side). Existing
files will be modified accordingly during the update.
- By default vias no longer generate Thermal symbols in supply
layers.
* Round SMDs
- SMDs have a new parameter "Roundness", which can range between
0 and 100 and defines the percentage by which the corners are
"rounded". A value of 0 (default) results in a rectangle, while
a value of 100 results in a circular shape (if the x and y
dimension of the SMD are the same), which can be used for BGAs.
- The SMD command accepts roundness values as numbers with a
leading '-' (to be able to distinguish it from the SMD size
values). The CHANGE command has a new option "Roundness".
* New Library structure
- What was called a "Device" in previous versions is now
called a "Device Set". A "Device Set" consists of the gate
definitions and several actual devices, implemented through
"Package Variants"
- The PACKAGE command can now assign several different package
variants to a device (as in 7400N, 7400D,...).
- The new command TECHNOLOGY can be used to define various
"technology" variants for a device's package variants (as in
74LS00N, 74S00N,...).
- The CHANGE command has the new options PACKAGE and TECHNOLOGY,
which can be used to select from the packages and/or technologies
a device set defines. This can be done from within the schematic
or board.
- The new command DESCRIPTION can be used to provide detailed
textual information about a device, package or library.
- The CONNECT dialog now allows copying pin/pad connections from
an other package variant. Only those package variants are offered
in the "Copy from" combo box that have the same pad names as the
current package variant (only connected pads are checked).
- The CONNECT dialog now asks the user if he want's to discard
any changes before cancelling the dialog.
- The CONNECT command can now handle gate names that contain
periods.
- The device editor now displays a list of package variants, a
preview of the current package and the description of the
device.
* Automatic Library update
- If a library has been modified after parts or packages from it
have been added to a schematic or board, the new command UPDATE
can be used to automatically update all used library objects with
their latest version (see "Help Update").
- The UPDATE command can be selected from the "Library" pulldown
menu in a board or schematic, or from the context menu of a
library in the Control Panel. It is also possible to drag&drop
a library from the Control Panel onto a schematic or board
drawing and perform the update that way.
* Bill Of Material
- The User Language Program 'bom.ulp' to generate the "Bill Of
Material" has been rewritten. It now has a dialog in which the
user can interactively generate the BOM, pulling in additional
data from a user defined database file. Use "RUN bom.ulp" and
click on the "Help" button for more information.
* Generating Outlines for milling prototypes
- The User Language Program 'outlines.ulp' can be used to generate
the data necessary to control a milling machine for generating
a prototype board.
* User Language
- The User Language now supports user defined dialogs as well as
standard file dialogs and message boxes.
- The RUN command now accepts additional arguments that are
available to the ULP as 'argc' and 'argv' parameters.
- Data can now be read into a ULP.
- The new lookup() function can be used to perform database
lookups.
- The new fileglob() function can be used to do a directory
search.
- The new fileerror() function can be used check for I/O errors.
- The 'exit()' function can now have a string parameter which is
sent to the editor window and executed as a command string.
- ULPs can now include other ULP files with the new #include
directive.
* Script files
- Script files can now call other scripts (as long as no
recursive call is made).
- Script files can now contain comments. Everything after
(and uncluding) a '#' character will be ignored.
- The 'eagle.scr' file is now first searched for in the current
project directory (which is equal to the current working
directory in case there is no project open) and then in the
directories listed in the Control Panel's
"Options/Directories/Scripts".
* Autorouter
- The Autorouter can now route "through" signal polygons (this
can be controlled by the new cost factor 'cfPolygon').
- The Autorouter control parameters are now stored inside the
board file. They can be saved to and loaded from external files
via the Autorouter dialog. Existing control files will be
automatically read and stored in the board file when updating
files from previous versions.
- The Autorouter and DRC now use the same set of Design Rules.
- When saving Autorouter control parameters to disk, the minimum
distance parameters are no longer part of that file.
- There can now be any number of 'Optimize' passes. By default
there are now 4 'Optimize' passes.
- Each pass can be separately activated or deactivated.
- The Autorouter can now route different wire widths and minimum
distances simultaneously by using "Net Classes".
- The minimum routing grid is now 0.02mm (about 0.8mil).
- The default control parameters and the internal handling of
cfChangeDir have been modified to avoid jagged tracks.
* ADD command
- The ADD command can now be used with wildcards ('*' or '?') to
find a specific device. The ADD dialog offers a tree view of
the matching devices, as well as a preview of the device and
package variant.
- To add directly form a specific library, the command syntax
ADD devicename@libraryname
can be used. 'devicename' may contain wildcards and
'libraryname' can be either a plain library name (like "ttl"
or "ttl.lbr") or a full file name (like
"/home/mydir/myproject/ttl.lbr" or "../lbr/ttl").
- If a device or package shall be added, and there is already
such an object (with the same name from the same library) in the
drawing, an automatic library update will be performed which
replaces the existing object in the drawing with the current
version from the library.
- The new command UPDATE can be used to update all parts in a board
or schematic with modified library versions (see "Help Update").
* CHANGE command
- CHANGE LAYER for wires and polygons now works between any
layers within packages and symbols.
* CONNECT command
- Pressing the SPACE key in the CONNECT dialog while a list element
has the focus will now perform the 'connect' or 'disconnect'
action, respectively.
* DELETE command
- If the last supply symbol of a given type is deleted from a net
segment that has the same name as the deleted supply pin, that
segment is now given a newly generated name (if there are no other
supply symbols still attached to that segment) or the name of one
of the remaining supply symbols.
* DISPLAY command
- The new parameters '?' and '??' can be used to control what
happens if a layer that is given in a DISPLAY command does not
exist in the current drawing. See "Help Display" for details.
* GROUP command
- If the selected group is empty, the GROUP command no longer
displays a message box saying "Group is empty". It rather prompts
that message in the status bar (with a beep) and stays active for
a new group definition.
* ERC command
- The ERC now lists the package names when reporting parts/
elements with inconsistent packages.
- The ERC now detects inconsistencies between the implicit power
and supply pins in the schematic and the actual signal
connections in the board.
- The ERC now checks for missing junctions and overlapping wires
and pins.
* ERRORS command
- The ERRORS dialog is no longer modal (it stays "on top" of the
editor window) and can be kept open while resuming normal
editing in the editor window. The various error types are now
listed more detailed.
* EXPORT command
- The EXPORT can now export image files (BMP, PNG, etc.). See
"Help/EXPORT" for details.
* NET and BUS command
- If a net wire is placed at a point where there is already
another net or bus wire or a pin, the current net wire will be
ended at that point (in previous versions the user had to click
twice to end a net wire).
* PASTE command
- When pasting objects into a drawing that already contains earlier
(different) versions of these objects, an automatic library
update will be performed which replaces the existing objects in
the drawing with the new versions from the paste buffer.
* PRINT command
- The PRINT dialog's "Page setup" now allows border values that
are smaller than the initial values derived from the printer
driver. To get back to the original default you can enter '0'.
* REMOVE command
- The REMOVE command can now handle device, symbol and package
names with extension (for example REMOVE name.pac).
* RENAME command
- The RENAME command now allows '.' in names.
- The RENAME command can now handle device, symbol and package
names with extension (for example RENAME name1.pac name2[.pac]
- note that the extension is optional in the second parameter).
* REPLACE command
- The REPLACE command can no longer be used with active forward-
and backannotation. This is due to the now complete definition
of a device set with all its package variants. Use the CHANGE
PACKAGE command to select one of the defined package variants,
or use the UPDATE command to update a package with a modified
version from the same library.
* SET command
- The SET options for Thermal and Annulus parameters as well as
the Solder Stop and Cream mask data have been removed.
- The SET variables DRC_SHOW and DRC_COLOR are now obsolete
(progress in the Design Rule Check is now displayed in a
progress bar).
- The SET variable MAX_ERROR_ZOOM is now obsolete. The ERRORS
dialog is no longer modal (it stays "on top" of the editor
window) and zooming can be done with the usual WINDOW commands
or buttons.
* SHOW command
- Highlighted objects are now kept highlighted during subsequent
window operations.
- Pressing ESCape in the SHOW command now lowlights the currently
highlighted object.
* USE command
- The USE command is now mainly for use in script files.
* CAM Processor
- The CAM Processor no longer supports matrix printers. Use the
PRINT command to print to the system printer.
- The CAM Processor no longer prints sheets. Use the PRINT
command instead.
* Parameter storage
- User specific parameters are now stored in an "eaglerc" file.
At program start, parameters are read (in the given sequence)
from the files
prgdir/eaglerc
/etc/eaglerc
$HOME/.eaglerc
where prgdir means the directory that contains the EAGLE program
file.
* Command line options
- The options '-A' and '-T' are now obsolete (thermal and annulus
data is now defined in the Design Rules).
- The options '-B' and '-M' are now obsolete (solder stop and
cream mask data is now defined in the Design Rules).
- The option '-C' is now obsolete, since the CAM Processor no
longer supports matrix printers (all printing is done with the
PRINT command).
- The options '-Z' and '-Y' are now obsolete (drill symbols are
configured in "Options/Set/Drill" and are stored in the user
specific "eaglerc" file).
* Miscellaneous
- The DOS and OS/2 platforms are no longer supported.
- Due to changes in the file data structure you will most likely
be asked whether to run the ERC when loading a board/schematic
pair created with an earlier version of EAGLE.
- Files from earlier versions of EAGLE may contain library objects
with the same names. This was caused by PASTE or ADD operations
with modified devices or packages. Version 4 no longer allows
this to happen, and therefore needs to make sure updated files
do not contain multiple objects with the same name. In order to
assure this, the update routine adds the '@' character and a
number to the names of such library objects.
- The library editor can now edit devices and symbols, even if the
user's license does not contain the schematic module.
- Avoiding multiple 'Save?' prompts for boards and schematics that
are connected via f/b annotation.
- When a file is modified while updating from a previous version
the resulting update report is now presented in a separate text
window.
