2022-03-12(cad/klayout) Updated 0.27.7 to 0.27.8mef1-4/+4
0.27.8 (2022-02-13): * Bugfix: %GITHUB%/issues/971 Double compare fails in LVS * Bugfix: %GITHUB%/issues/972 CIF writer generates unreadable file with invalid cell or layer names * Bugfix: %GITHUB%/issues/973 Enhanced timeout in package manager on large file download * Bugfix: %GITHUB%/issues/979 Backup file generation fails with relative paths * Bugfix: %GITHUB%/issues/982 Heal option for tiled XOR * Bugfix: %GITHUB%/issues/983 Bug changing PCell parameters of multiple cell instance * Bugfix: %GITHUB%/issues/984 Crash in debug mode when placing a "slow cell" * Bugfix: %GITHUB%/issues/994 Loss of selection when clicking at wrong position To make this problem less annoying, the capture range was increased when clicking at already selected items for "Move". * Bugfix: %GITHUB%/issues/995 New top cell appearing after load * Enhancement: %GITHUB%/issues/996 Refresh function to trigger update from within library * Bugfix: %GITHUB%/issues/997 Wrong display of negative extensions of paths * Bugfix: scale and grids were wrong in case of oversampling
2022-01-24(cad/klayout) Updated 0.27.5 to 0.27.7mef1-4/+4
0.27.7 (2022-01-12): * Bugfix: %GITHUB%/issues/969 PCell error (infinite recursion) 0.27.6 (2022-01-04): * Enhancement: %GITHUB%/issues/963 Display snapped position in main window * Bugfix: %GITHUB%/issues/960 Cap values range now shown in netlist browser * Bugfix: %GITHUB%/issues/954 Fixed a device extraction glitch * Bugfix: %GITHUB%/issues/951 Internal error fixed when deleting the cell you're sitting at Side effect: copy & paste of cells is correctly disabled now in viewer mode * Bugfix: %GITHUB%/issues/942 Technology file routing suffix string typo * Bugfix: %GITHUB%/issues/946 Python: __file__ returns quoted path string * Bugfix: DRC check for equal width now returns more consistent results Previously, a check like "layer.drc(width == something)" was not flagging all candidates correctly. * Enhancement: A PCell can request "lazy evaluation" now This means that a parameter change needs to be committed in the UI before it is being taken. This way, slow PCell evaluation will not make the application stall. To add this feature, reimplement "wants_lazy_evaluation" in the PCell class to return "true". * Enhancement: "lvs_data" is a global function now in LVS scripts * Bugfix: less liberal evaluation of expressions in string to numeric conversion This will fix a potential vulnerability which allows someone to sneak in expression code through malicious configuration, technology or layer properties files.

Using 1016 AC1014 seems to require much more meta information I cannot provide without deeper insight into the DXF structure.
2021-05-29(cad/layout) Udated 0.26.11 to 0.27 based on wip/klayout by Atsushi Toyokuramef1-6/+5
0.27 (2021-05-02): * Enhancements: Numerous new functions for the RBA and pya API Some highlights: * "Texts" for text collections (similar for Edges/EdgePairs/Region) * New modes for blending layout files - see GitHub issue #666 * New function Cell#transform - see GitHub issue #598 * New functions for Image (read, write, clear) * New functions for Region and Edges correlating with the new DRC features * Multi-cell hierarchical copy/move of trees - will maintain shared instances * RBA: iterators are now automatically made available as Enumerable * All functions having a void return specification now return self (allows chaining) * More functions for manipulating selections (LayoutView#select_all etc.) * Spline interpolation code available in new "Utils" namespace * QByteArray support, mapping to Python byte arrays * MainWindow#set_key_bindings, MainWindow#get_key_bindings, MainWindow#set_menu_items_hidden etc. * New class RecursiveInstanceIterator (similar to RecursiveShapeIterator, but acts on instances) * Deep vs. flat operations do not always flatten out now (flat vs. deep does however) * Global transformations for inputs * Enhancements: New DRC features Some highlights: * Better support for texts - "text layers" * Combined AND+NOT feature for separating regions into inside and outside part * "max_vertex_count" and "max_area_ratio" configuration options * "forget" for memory optimization * Shielding is optional now for some DRC functions * "interact" now has a count filter * In verbose more, figure counts and more information is printed * Generic DRC function and complex DRC operations: for details search "Universal DRC" in documentation * "not_opposite" and "rect_filter" options for some DRC functions * "enclosing" (selects polygons entirely enclosing others) * New filters for polygons: squares, non_squares, area ratio, bbox aspect ratio * More intuitive specification of projection limits ("projecting < 2.um") * "with_holes" and "without_holes", also with count * Density check is included now ("with_densitiy", "without_density") * "split_..." functions give interacting/non-interacting sets in one step * Better support for generic transformations as Matrix2d and Matrix3d * "fill" and "fill_with_left" functions for dummy fill * NO "connected" feature yet. Sorry. Had to drop it to finish this release. * Enhancements: new LVS features Some highlights: * Improved netlist and LVS result browser (infinite-depth browsing) * Improved circuit match algorithm * Case insensitive handling of object names for SPICE netlists * Probe feature fixed in flat mode * "connect_explicit": for details search "connect_explicit" in documentation * Enhancements: New features for images Some highlights: * New menu item: show and hide all images - see GitHub issue #535 * False color nodes now can have a left and right color allowing color steps * Persistance of images through a special file format: "lyimg" (XML based) * Enhancements: LEF/DEF reader Some highlights: * Support for layer map files * More complete spec support (e.g. FILL, MASK, FOREIGN, DO/BY/STEP ...) * Several bug fixes, e.g. routing layer switch for VIAs * Some functions also act on the transient selection (less mouse clicks) * Enhancements: Layout editing and rulers Some highlights: * Object properties now are changed without having to commit the dialogs * Dockable editor options windows * "Recently used" list * A "distribute objects" feature (Edit/Selection/Distribute) * Snap highlighting * Mouse tracking cursor indicates grid- and object-snapped location * Enhancements: Help browser * Bookmarks * Search in page (Ctrl+F) * Enhancement: Improved fill tool The fill tool now also supports skewed fill pattern repetitions * Enhancement: Ability to utilize a LayoutView as a Widget Standalone instantiation of a LayoutView object is supported now. So it becomes possible to create custom MainWindow UIs and embed a layout view there. * Enhancement: Improved layer and cell list filtering and searching * Enhancement: Experimental 3d (called 2.5d) view of layout For details search "2.5d View" in documentation. * Enhancement: Improved performance on sea of instances for OASIS files Iterated OASIS instances are stored and handled in a leaner way in viewer mode * Enhancement: Buddy scripts can concatenate files with "+" for input Concatenation happens by "blending files". Beware of the risk this implies. A new option "--blend-mode" has been introduced for supporting overwrite, skip and variant formation in case of cell name conflicts. See buddy script help. * Enhancement: Layer maps now support n:m layer mapping This allows mapping n input layers to one logical layer (merging) and also one input layer to m logical ones (clone layer). This applies to the buddy scripts and layer maps inside KLayout's reader. * Enhancement: include mechanism for easy include of files into DRC/LVS scripts This is a plain text substitution feature. Don't use it for Ruby or Python scripts (the preferred way is still require/import). But it's a quick way to include partial DRC and LVS scripts without having to worry about variable scope. For details see "Including other files" in the documentation under: KLayout User Manual/Design Rule Check (DRC)/DRC Runsets. * Bugfix: %GITHUB%/issues/771 Fixed an issue with QByteArray/QVariant transformation in Qt binding * Bugfix: %GITHUB%/issues/750 PCB gerber import: Incorrect handling of D02 operations. * Bugfix: %GITHUB%/issues/747 Proper handling of comments in RVE DB reader * Bugfix: %GITHUB%/issues/740 Bug in the "smooth" function. * Enhancement: %GITHUB%/issues/715 A separate search range can be specified for box selections now * Enhancement: %GITHUB%/issues/691 Technology specific libraries: library name resolution based on technology. * Enhancement: %GITHUB%/issues/666 Controlling the way a layout reader integrates cells into an existing layout. * Bugfix: %GITHUB%/issues/663 Deep mode DRC: separation from "inside" gives wrong errors. * Enhancement: %GITHUB%/issues/648 LVS could not do "connect_implicit" with global nets. * Bugfix: %GITHUB%/issues/609 Internal error on net extraction. * Enhancement: %GITHUB%/issues/598 Plain transformation of cell missing. * Enhancement: %GITHUB%/issues/588 RBA/PYA: Provide event when a net is selected in the netlist browser. * Enhancement: %GITHUB%/issues/563 True support for text objects in DRC/LVS (text layers). * Enhancement: %GITHUB%/issues/558 Edges#extents, Texts#extents and EdgePairs#extents now work hierarchically in deep mode. In DRC, this means, "extents" is a deep-enabled method now. * Enhancement: %GITHUB%/issues/535 Image handling enhancements. * Enhancement: %GITHUB%/issues/521 Enhanced API for ObjectInstPath. * Enhancement: %GITHUB%/issues/487 Difficult to select specific labels for net name assignment in net extraction. Solution involves a more elaborate handling of texts through "text layers. 0.26.12 (2021-04-21): * Bugfix: %GITHUB%/issues/747 Result browser gives error message with // lines in RVE files * Bugfix: %GITHUB%/issues/771 Problem with QMimeData binding
2021-05-24(cad/klayout) Updated 0.26.10 to 0.26.11 based on the wip/klayout by Atsushi ↵mef1-6/+5
Toyokura, thanks (0.27.0 is again, waiting) 0.26.11 (2021-02-27): * Bugfix: %GITHUB%/issues/733 Relative path resolution in session files fails when the session file's path contains "+" characters * Enhancement: %GITHUB%/issues/730 Support of class 'QUiLoader' in PYA and RBA * Bugfix: %GITHUB%/issues/728 Fails to build on Debian hppa: uses non-standard sa_restorer field of struct sigaction * Bugfix: %GITHUB%/issues/726 Crash on LayoutView#clear_selection on Linux. * Bugfix: %GITHUB%/issues/723 Backup scheme wasn't working correctly with a single file without path given as command line argument.
2021-05-22(cad/klayout) Updated 0.26.8 to 0.26.10 ( 0.26.11, 0.27.0 are waiting)mef1-10/+10
Based on wip/klayout (a little bit old version) by Atzushi Toyokura work. (pkgsrc) - rename patch - Add comment on patches - more PLIST_SUBST (upstream changes) 0.26.10 (2020-02-02): * Enhancement: %GITHUB%/issues/720 "Safe save" and backups: when saving files, the file is only overwritten after the save terminated successfully. This will avoid loss of data for full volumes or network share dropouts. In addition, a configurable number of back files can be kept (see File/Setup: Application/General). * Bugfix: %GITHUB%/issues/718 GDS export issue fixed (breaking of polygons was filling holes) * Bugfix: %GITHUB%/issues/709 LVS compare enters infinite loop when it encounters two entirely identical subcircuits * Bugfix: %GITHUB%/issues/708 Qt binding: missing support for binary strings as QByteArray representative * Bugfix: %GITHUB%/issues/707 QJsonValue's string constructor is ambiguous * Bugfix: %GITHUB%/issues/704 Rational Splines not supported DXF * Bugfix: %GITHUB%/issues/693 MAGIC files won't find subcells when reading from command line * Bugfix: HTTP stream reading issue with redirect At least on MacOS a segfault happened when reading HTTP stream data (e.g. for package manager) from addresses which are redirected. * Enhancement: Removed %APPDATA% from DLL search path on Windows This will avoid installation poisoning by the one from %APPDATA% (which ironically is the default installation path). Eventually multiple versions can be used in parallel. 0.26.9 (2020-11-27): * Bugfix: %GITHUB%/issues/658 Menu items were not put into the right place on MacOS. * Bugfix: %GITHUB%/issues/652 "M" factor scaling was not working for Spice reader. * Bugfix: %GITHUB%/issues/651 Fixed an issue with DRC "select". * Bugfix: %GITHUB%/issues/647 Text orientation was not considered properly in search & replace * Bugfix: %GITHUB%/issues/646 A potential crash was fixed happening when a PCell library is deleted * Bugfix: Display bug Cell placements with small magnification factors (such that the viewport dimensions exceeded the DBU space when seem from inside the cell) lead to display errors.
2020-10-30(cad/klayout) Updated 0.25.9 to 0.26.8 by Atsushi Toyokura <asteria.at (at) ↵mef1-7/+7
gmail.com> 0.26.8 (2020-09-15): * Enhancement: %GITHUB%/issues/639 A new method is available which enables copying of multiple cells into a target layout while maintaining common subcells are single cells. * Bugfix: %GITHUB%/issues/637 Points have not been selected properly when inside mirrored subcells in partial edit mode. * Bugfix: %GITHUB%/issues/629 Qt5 QTimer timeout signal was not available to Python or Ruby. This also applied to all "private" signals of Qt5. QTimer is just one important example for this case. * Bugfix: %GITHUB%/issues/617 A problem with pseudo-const Python/Ruby objects in the netlist API was fixed. * Bugfix: %GITHUB%/issues/615 Basic authentication for package manager now uses UTF-8 encoding. Most servers expect this kind of encoding today. UTF password characters are supported this way. 0.26.7 (2020-07-07): * Bugfix: %GITHUB%/issues/381 and more Some bugs fixed that happened specifically on MacOS. 1.) A segfault that happened in LVS 2.) Some classes were not properly registered for usage in scripts. * Bugfix: %GITHUB%/issues/493 LVS asserted on MacOS * Enhancement: %GITHUB%/issues/586 As a safety feature, the stream writers now refuse to write layouts with cells carrying the same names. Writing such layers would result in corrupted or invalid layout files. * Bugfix: %GITHUB%/issues/589 (tentative) On Anaconda-based builds for MacOS 10.15 (Catalina) a loss of instances was observed. This could be traced down to compiler/library incompatibilities but not further. * Enhancements: %GITHUB%/issues/591 Two enhancements in the macro editor: 1.) A crash happening when adding a new location was fixed 2.) The template selection popup can now be disabled by dismissing the tip dialog. * Bugfix: %GITHUB%/issues/592 Reading a file into a layout with unnamed layers caused problems with layer mapping specs. * Bugfix: %GITHUB%/issues/596 Library#_destroy was crashing the application. As this function must not be called, it's rerouted to "nothing" for backward compatibility. * Enhancement: %GITHUB%/issues/603 The "adjust origin" feature now allows specifying the target coordinates for the adjustment. * Bugfix: %GITHUB%/issues/610 An internal error happened for certain hierarchical configurations on netlist extraction. * Enhancement: LVS netlist compare The algorithm was improved to provide better reproducibility. The detection of matching paths in the presence of ambiguities was improved. In addition, the netlist compare now favours net names for resolving ambiguities. So if nets are named the same in the layout and the schematic, ambiguities are resolved based on these names. This is usually more efficient. A new function is available to turn this feature off: "consider_net_names(false)". 0.26.6 (2020-06-05): * Enhancement: %GITHUB%/issues/522 Skip comment lines with // in RVE DB reader * Bugfix: %GITHUB%/issues/547 Doc fixes, better error messages on some Shape methods * Bugfix: %GITHUB%/issues/555 Using 64bit coordinates on RVE reader to avoid overflow * Bugfix: %GITHUB%/issues/565 Spice reader: .global should not add pin if the signal isn't used in a subcircuit * Bugfix: %GITHUB%/issues/568 and %GITHUB%/issues/578 A CIF reader and writer bug was fixed * Bugfix: %GITHUB%/issues/570 and %GITHUB%/issues/579 Perimenter can be included in antenna area for the antenna check. This also includes a mode in which only the perimeter is considered. * Enhancement: %GITHUB%/issues/560 A library can be associated with multiple technologies now. * Bugfix: width of cell and library side panels could not be reduced below the width of the selection boxes in the header * Bugfix: cell view selection header text did not get updated when saving the layout to a different file 0.26.5 (2020-05-02): * Bugfix: %GITHUB%/issues/539 An internal error happened on netlist flatten sometimes * Bugfix: %GITHUB%/issues/524 Failed queries leave layout in undefined state * Bugfix: %GITHUB%/issues/525 Report true source line in DRC and LVS verbose mode * Bugfix: %GITHUB%/issues/526 Makes script debugging more reliable * Enhancement: %GITHUB%/issues/527 Wildcard layer mapping for stream readers * Bugfix: %GITHUB%/issues/544 Duplicate .global statements in SPICE netlists created duplicate pins * Bugfix: %GITHUB%/issues/548 A shielding issue was fixed for DRC space measurements * Bugfix: diff tool bug with paths Differences in path points where no reported * Enhancement: documentation clarifications and typos fixed 0.26.4 (2020-03-02): * Bugfix: %GITHUB%/issues/517 DEF reader could not read VIAS+VIARULE without pattern * Enhancement: %GITHUB%/issues/471 Leaner way to specify LVS compare tolerances for device parameters * Enhancement: %GITHUB%/issues/473 Direct access to image data in scripts (array of values instead of per-pixel calls) * Bugfix: %GITHUB%/issues/476 Issues with "target" switching in DRC solved * Bugfix: %GITHUB%/issues/477 Missing letter "J" in Times font .. actually this bug is of 1967. * Bugfix: %GITHUB%/issues/478 Layout queries could not use the "shapes" method * Bugfix: %GITHUB%/issues/481 "isolated" DRC function reported duplicate marker shapes * Enhancement: %GITHUB%/issues/482 "join_symmetric_nets" feature in LVS for implementing "split gate" configurations * Enhancement: %GITHUB%/issues/486 There is a "save as" function available now in the macro editor (in context menu of the macro tree) * Enhancement: %GITHUB%/issues/489 Pin names can be attached as properties to port and pin shapes when reading LEF or DEF * Bugfix: %GITHUB%/issues/491 Performance enhancement of L2N/LVS DB file loader * Bugfix: %GITHUB%/issues/496 Fixed builds on CentOS 8 and Fedora 31 * Enhancement: %GITHUB%/issues/500 Option to limit number of shapes for net tracer * Bugfix: %GITHUB%/issues/501 Issues with ownership transfer fixed in Qt binding * Bugfix: %GITHUB%/issues/502 Issues with AbsoluteProgressReporter in scripts fixed 0.26.3 (2020-01-05): * Bugfix: %GITHUB%/issues/466 A crash happened when accessing layer properties tabs with an invalid index in Ruby or Python * Bugfix: %GITHUB%/issues/464 Problem building a layer tree with "add_child" (Ruby/Python) * Bugfix: %GITHUB%/issues/463 Configuring a layer color with a group node was not effective over multiple levels of hierarchy * Enhancement: %GITHUB%/issues/462 MOS transistor gate figures can be more generic now, e.g. ring-like or non-rectangular * Bugfix: %GITHUB%/issues/458 A net extraction bug related to certain array/array interactions is fixed 0.26.2 (2019-12-18): * Bugfix: %GITHUB%/issues/453 A crash happened when the "inverse" button is used on the TEXT PCell * Bugfix: %GITHUB%/issues/449 The Qt windows styling plugin is now installed too on Windows. * Bugfix: %GITHUB%/issues/448 The LVSDB database wasn't written with the proper device class statements in short form. * Bugfix: %GITHUB%/issues/447 Net extraction did not work properly on a specific test case with folded and interleaving array instances. * Bugfix: %GITHUB%/issues/445 "Selection/Merge shapes" gave cryptic message when instances are selected * Enhancement: %GITHUB%/issues/444 Support for net joining though labels also for specific subcells (here: to support double-height standard cells) * Bugfix: %GITHUB%/issues/440 LayoutView#each_annotation_selected wasn't working * Enhancement: %GITHUB%/issues/438 Redefining a circuit in Spice netlists will give an error now * Enhancement: %GITHUB%/issues/436 Option to silence instance copy mode dialog, Enhancements to interactive move, duplicate and copy (sensitive to transient selection now) * Enhancement: %GITHUB%/issues/434 New preinstalled Ruby gems and Python packages (e.g. numpy, scipy, test/unit for Ruby) for the Windows packages. * Bugfix: %GITHUB%/issues/429 Support for MAGIC file format (*.mag) * Enhancement: %GITHUB%/issues/428 Edit buttons are not shown in user properties dialog in viewer mode * Enhancement: %GITHUB%/issues/426 Techs can be grouped in menu now * Enhancement: %GITHUB%/issues/425 Don't generate dummy pins for dummy gates * Bugfix: %GITHUB%/issues/419 Multiple top circuits after flatten of netlist * Bugfix: %GITHUB%/issues/417 Probe nets does not work with flat extraction on Tools/Trace All Nets/Flat * Bugfix: %GITHUB%/issues/415 and %GITHUB%/issues/439 Macros need to be stored with CRLF on Windows for management with a versioning system like git * Enhancement: %GITHUB%/issues/411 Multiple device extractors for same class * Bugfix: %GITHUB%/issues/410 Errors were not reported on "rerun" from the DRC and LVS report dialogs * Bugfix: %GITHUB%/issues/408 Internal error after EdgePairs#polygon * Enhancement: %GITHUB%/issues/407 Variables can be used in technology base path now - $(tech_name) -> substituted by the technology name - $(tech_dir) -> substituted by the directory the technology file is stored in - $(tech_file) -> substituted by the absolute path to the tech file - $(appdata_path) -> substituted by KLayout's home directory (e.g. ~/.klayout) - $(env('X')) -> substituted by the environment variable $X * Enhancement: %GITHUB%/issues/406 DRC edge layers: AND between intersecting edges gives point-like markers indicating the intersection points * Enhancement: netlist object properties User properties can be attached to the following netlist objects now: Pin, Device, Circuit, Net and SubCircuit. Properties are key/value pairs (keys and values can be strings can be strings or numbers). The property-enabled classes use "NetlistObject" as the base class now. NetlistObject provides "set_property" to set or reset a property and "property" to retrieve one. Properties are persisted in L2N and LVSDB files and written to layout shapes on "build_nets". * Enhancement: more detailed progress On certain nested operations, a double or triple progress bar is shown indicating the progress of nested operations. 0.26.1 (2019-11-06): * Bugfix: %GITHUB%/issues/354 Buddy scripts did segfault. * Bugfix: %GITHUB%/issues/352 LVS: equivalent_pins required the cell to be present. * Enhancement: %GITHUB%/issues/353 Session files: "file-path" and "rdb-file" behavior was inconsistent. * Bugfix: %GITHUB%/issues/358 "strm2oas" was writing GDS files. * Bugfix: %GITHUB%/issues/363 It was possible to produce bad polygons while drawing. * Bugfix: %GITHUB%/issues/372 pymod build failed with HAVE_64BIT_COORD=1. * Enhancement: %GITHUB%/issues/376 Parameters UI callback invoking. * Bugfix: %GITHUB%/issues/368 Segfault with layer list manipulation while iterating. * Bugfix: %GITHUB%/issues/386 "None" is a reserved keyword for Python binding - use "None_". * Enhancement: %GITHUB%/issues/382 Possibility to copy user property value. * Enhancement: %GITHUB%/issues/387 Salt: Python version can be specified in "api-version". Other requirements can be specified too. * Bugfix: %GITHUB%/issues/392 Layers "Style" sub-pane was malformed. * Enhancement: %GITHUB%/issues/394 Even bigger font sizes for rulers and labels for the 4k age: Now there is "XLarge", "XXLarge" and "XXXLarge" as well. * Enhancement: %GITHUB%/issues/393 DRC syntax errors are now shown in their original code line of the DRC script. * Bugfix: %GITHUB%/issues/400 Snap feature wasn't working for deep regions in certain use cases. * Enhancement: new "scale_and_snap" methods These methods allow scaling and snapping of layouts. Scaling is supported by a rational factor. After scaling, snapping can be applied to an integer grid. There are two incarnations. Region#scale_and_snap (or Region#scaled_and_snapped): this is a flat implementation which allows anisotropic scaling/snapping as well. And there is Layout#scale_and_snap which is a fully hierarchical scale-and-snap feature. The latter does not support anisotropic scaling/snapping, but works hierarchically without opening gaps. It operates on a top cell and on all layers. * Enhancement: new Region#pull_* methods and DRC features "pull_*" is a class of methods that allows rehierarchisation of shapes. These methods act similar to "interacting", but the other way around: instead of delivering interacting shapes of the first argument, it will deliver shapes of the second argument. For example, "a.pull_interacting(b)" will deliver polygons of b which interact with polygons of a. As a side effect, the polygons of b will be stored hierarchically close to the polygons of a. This provides a way to "re-hierarchise" layout. The full class of methods and DRC functions involve: Region#pull_interacting, Region#pull_inside, Region#pull_overlapping and the same functions for DRC. "pull_interacting" is also available for the Edges class and edge layers in DRC. * Enhancement: Net tracer bug fix for heavily decomposed polygons The net tracing feature now can operate on heavily decompose polygons as well. Such layouts can be created by using a low max. vertex count on GDS write. The problem were small triangles with an area of 0.5 square DBU. * Enhancements: General fixes of deep DRC mode Some inconsistencies with merged/raw mode have been removed. Performance was enhanced in a few places. Multithreaded mode now works more reliably. * Enhancements/bugfixes: various LVS improvements The backtracking algorithm should work more reliable in cases of ambiguities and floating nets or pins. Performance should be better in some cases. LVS script structure is less rigid now. "cheats" to forcibly ignore hierarchy interactions for some cells (useful for SRAM layout for example). Still there is some work to do. 0.26 (2019-09-10): * Bugfix: %GITHUB%/issues/197 Python: Reimplemented methods are not getting called * Bugfix: %GITHUB%/issues/236 Crash when using "Delete all rulers" * Bugfix: %GITHUB%/issues/251 Register application exit handler in Ruby * Bugfix: %GITHUB%/issues/264 Python exceptions are redirected when PCell is used * Bugfix: %GITHUB%/issues/265 LEF file can't be read * Bugfix: %GITHUB%/issues/277 Region#min_coherence is not recognized by Region#sized * Bugfix: %GITHUB%/issues/293 File/Setup menu and dialog names are inconsistent * Bugfix: %GITHUB%/issues/294 Cannot display the right icon in Ubuntu * Bugfix: %GITHUB%/issues/302 Display issues with small cells * Bugfix: %GITHUB%/issues/305 CIF box positions are incorrect when a rotation is specified * Bugfix: %GITHUB%/issues/306 Round corners issue * Bugfix: %GITHUB%/issues/316 Text capture box has zero dimension for move * Bugfix: %GITHUB%/issues/318 Unable to disable a key binding * Bugfix: %GITHUB%/issues/321 Something's wrong with tip windows * Bugfix: %GITHUB%/issues/322 CIF, error when changing layer name while file open in KLayout * Bugfix: %GITHUB%/issues/330 DXF reader stalls * Bugfix: %GITHUB%/issues/337 Annotation: make "cross" styles available for scripts * Bugfix: %GITHUB%/issues/338 Unreadable Assistant document: QComboBox * Bugfix: Rare crash fixed with line width > 1 With line widths > 1, segfaults have been observed in some rare cases. * Enhancement: %GITHUB%/issues/287 Return an ObjectInstPath from the RecursiveShapeIterator * Enhancement: %GITHUB%/issues/317 "infix move" * Enhancement: %GITHUB%/issues/333 Ruby/Python automation of "auto measure" * Enhancement: %GITHUB%/issues/342 Ruler properties editor: swap points and snap to object buttons * Enhancement: %GITHUB%/issues/343 Dockable bookmark window * Enhancement: Hierarchical mode for DRC ("deep" keyword) DRC can be put into hierarchical mode with the "deep" statement at the beginning of the file. In hierarchical mode, most operations are performed in a hierarchical fashion - i.e. trying to maintain as much from the original hierarchy as possible. * Enhancements: Antenna checks for DRC DRC now got an antenna check feature. Netlist extraction is the basis for this feature. * Enhancement: Hierarchical mode in XOR tool and "strmxor" The XOR tool and the "strmxor" buddy tool provide switches to enable hierarchical mode. These options are considered experimental currently as XOR between two different layouts was not the implementation goal. * Enhancement: Netlist extraction KLayout supports extraction of netlists from a layout. This is the first step towards LVS. This feature includes an infrastructure providing netlist data structures (with Ruby/Python bindings), Netlist readers and writers (Spice format), device recognition and a netlist browser. * Enhancement: LVS The LVS feature is based on the netlist extraction capabilities. It adds netlist vs. netlist compare and the corresponding infrastructure. LVS is a new script environment that is based on the DRC feature and extends the DRC script language by LVS elements. * Enhancement: Command line option -mn to open netlist database * Enhancement: Net tracer "trace all nets" Based on the netlist extraction feature, an alternative mode for net tracing is provided. With "trace all nets", no a single but all nets are traced at once. Probing then happens in the final nets extracted rather than providing the seed shape. "Trace all nets" operates in hierarchical mode and therefore usually is faster and has a smaller memory footprint when extracting huge nets such as power nets. * Enhancement: Library browser The library browser is a dockable tool window which shows all libraries installed. Use drag and drop to place a library cell from the library browser in edit mode. * Enhancement: Layout query enhancements Layout queries (aka "Search and replace") now allow specification of Variables when using the script API. The performance of queries has been enhanced in the case of cell tree recursion. * Enhancement: Gridline colors The grid lines (or dots, depending on the style) can now be given different colors for axes, grid lines and the ruler inset. * Enhancement: Multiple files on import The "File/Import/Other files into current" feature now allows importing multiple files into the current layout. * Enhancement: Python standalone module KLayout supports production of standalone Python modules which provide the same features than the "pya" module but for use without the KLayout binary. If installed properly, "import klayout" will pull in all modules. "import klayout.db" will pull in the database part. Deployment on PyPI is supported. * Enhancement: Modal help dialog from modal windows When using Assistant links in the UI, the assistant now is shown as a modal window when called from a modal dialog. Before, the Assistant window wasn't usable in this case.

2018-09-22Updated cad/klayout to 0.25.4mef1-5/+5
0.25.4 (2018-08-25): * Bugfix: https://github.com/klayoutmatthias/klayout/issues/121 Issue with multiple reads of GDS2 layouts including PCells * Bugfix: https://github.com/klayoutmatthias/klayout/issues/134 Error in cell.fill_region caused by big polygon with spikes * Bugfix: https://github.com/klayoutmatthias/klayout/issues/139 Libraries have not been reassigned when loading a GDS file from command line (does not happen on File/Open) * Bugfix: https://github.com/klayoutmatthias/klayout/issues/141 Issue with RBA::QHostAddress (ambiguous overload) on Qt5 * Bugfix: https://github.com/klayoutmatthias/klayout/issues/142 Issue with RBA::RecursiveShapeIterator#region= * Bugfix: https://github.com/klayoutmatthias/klayout/issues/144 The Salt package descriptions are not shown with Motif style * Bugfix: https://github.com/klayoutmatthias/klayout/issues/148 Wrong font is used * Bugfix: https://github.com/klayoutmatthias/klayout/issues/152 Shapes#size reported a wrong shape count in viewer mode * Bugfix: https://github.com/klayoutmatthias/klayout/issues/153 Application crash when editing guiding shape properties * Bugfix: https://github.com/klayoutmatthias/klayout/issues/155 Program freezes after replacing nothing by something in Macro editor * Bugfix: https://github.com/klayoutmatthias/klayout/issues/157 "Replace cell with ..." rejected cell names with a library prefix * Bugfix: https://github.com/klayoutmatthias/klayout/issues/158 Repaint issue on cell context * Bugfix: https://github.com/klayoutmatthias/klayout/issues/159 Tech specific macros and DRC scripts were not shown in tech manager * Bugfix: 8 bit indexed GIF images can be used for package icons now * Enhancement: Provide a way to specify the type of a macro This feature is mainly useful for command line arguments. If you run KLayout with "klayout -b -r myscript" it will not be able to determine the type of macro without a suffix. You can now explicitly specify a certain type by giving the suffix implicitly like: "klayout -b -r myscript[rb]" This will read "myscript" but pretend it was "myscript.rb" and execute it as Ruby script. This feature is handy if you need to run a file with a specific interpreter but cannot modify the file name. * Enhancement: Selection now shows PCell display names Before, the internal name was shown for instances * Enhancement: There is an option in the View menu to show or hide markers Markers may hide layout under them. With this feature you can quickly disable all markers and the layout becomes visible.
2018-07-24Update to 0.25.3ryoon1-11/+10
* Use Qt 5 instead of Qt 4 Changelog: 0.25.3 (2018-05-03): * Enhancement: Compile option to use libcurl instead of QtNetwork This workaround enables builds on the native CentOS6 configuration with the package manager functional. * Enhancement: Pass label (text) layers through DRC script The "labels" method now allows copying labels from a layer to the output. * Enhancement: New "split" method for polygons This method will fragment the polygons into two or more smaller parts for reducing their vertex count. * Enhancement: New "dtrans" method for RecursiveShapeIterator This method delivers the transformation in micron unit space * Enhancement: New "insert" methods for Shapes Shapes can now insert from another Shapes container and from a RecursiveShapeIterator. Possible applications are fast flattening and fast region selection. * Enhancement: New method to generate RDB items from shapes RdbItem#add_value from a shape, RdbDatabase#create_items from a shapes container or recursive shape iterator and RdbDatabase#create_item from a shape. * Enhancement: DXF and CIF "keep layer names" If this option is set in the reader options, layer names are not translated into GDS layer/datatype pairs. Specifically a layer called "L5" for example is not translated to 5/0 and to "L5D0" on output correspondingly. The buddy script option is "--keep-layer-names". * Enhancement: DXF contour joining accuracy On the DXF reader's options, a contour joining accuracy can be specified. Small gaps smaller than this accuracy will be closed when forming joined contours from edges. The buddy script option is --dxf-contour-accuracy=value. * Bugfix: DXF display issue In some cases, DXF cell instances did not trigger bounding box update and the cells only got visible after save and load. * Bugfix: XOR progress is more realistic The progress is updated after the layer has been computed, not before. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/117 DTrans#itype was broken. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/116 Fixed a polygon decomposition bug when writing GDS files with big polygons with many holes. As a side effect, the polygons with many holes computed by a NOT operation for example are less complex and spikes in the cutlines are avoided. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/115 Reader options were not persisted. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/114 Custom line styles not loaded from tech's layer properties file. * Enhancement: https://github.com/klayoutmatthias/klayout/issues/113 The XOR tool has an option now to heal result shapes which cross tile boundaries. The result shape count of tiled and non-tiled mode should basically be the same then. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/112 Salt package repository relative paths have not been working. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/109 Issues with Python 3 and shape properties - property * Bugfix: https://github.com/klayoutmatthias/klayout/issues/108 Bugfix on Box#enlarge and Box#moved for empty boxes. keys generated with Python 3 could not be written to GDS2. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/107 Undo not working with shapes. * Enhancement: https://github.com/klayoutmatthias/klayout/issues/106 Search & replace help page enhancements. 0.25.2 (2018-03-20): * Bugfix: https://github.com/klayoutmatthias/klayout/issues/90 DRC: "extended" was not working as expected with "joined = true" * Bugfix: https://github.com/klayoutmatthias/klayout/issues/89 Display issue on MacOS fixed * Enhancement: https://github.com/klayoutmatthias/klayout/issues/85 IDE debugger: files can be excluded from showing exceptions when they are thrown. To exclude a file press the new "Ignore" button when the debugger tells you an exception has been generated. To re-able exception reporting, clear the list of the files in the IDE settings ("Debugging" tab) The macro IDE settings can now be edited in the File/Setup dialog. * Bugfix: https://github.com/klayoutmatthias/klayout/issues/94 Retina displays are support to some extend on MacOS. An open topic is the quality of the icons. * Enhancement: build system for MacOS 0.25.1 (2018-02-23): * Enhancements: build compatibility with MacOS and Qt 5.9. Qt 4.6 supported now as well with one restriction: the package installation feature is not working. * Bugfixs: Package manager - Remove button wasn't enabled if multiple packages were selected - A potential crash ob removing packages was fixed * Enhancement: 64 bit coordinate support enabled on Windows builds * Further bugfixes: See links - https://github.com/klayoutmatthias/klayout/issues/21 (Autorun(-early) doesn't seem to run when lym files are inside a package) - https://github.com/klayoutmatthias/klayout/issues/24 (Text insert dialog bug - Ok button isn't working) - https://github.com/klayoutmatthias/klayout/issues/26 (Exceptions are reported every time they propagate up in the call chain in the ruby debugger) - https://github.com/klayoutmatthias/klayout/issues/28 (CIF format detection failed) - https://github.com/klayoutmatthias/klayout/issues/30 (Writer options dialog non-functional on a fresh configuration) - https://github.com/klayoutmatthias/klayout/issues/32 (Rounding issue with instance properties) - https://github.com/klayoutmatthias/klayout/issues/33 (Plugin factory not working when using with Python) - https://github.com/klayoutmatthias/klayout/issues/36 (Hardening against destruction of object inside event handler) - https://github.com/klayoutmatthias/klayout/issues/39 (Action cannot be reassigned) - https://github.com/klayoutmatthias/klayout/issues/40 (Crash in Python binding) - https://github.com/klayoutmatthias/klayout/issues/41 (Polygon#touches? issue) - https://github.com/klayoutmatthias/klayout/issues/42 (Headless mode support with Qt5/-zz) - https://github.com/klayoutmatthias/klayout/issues/43 (Crash when using Qt specific command line options) - https://github.com/klayoutmatthias/klayout/issues/44 (Transformation constructor with x,y not working) - https://github.com/klayoutmatthias/klayout/issues/45 (Partial selection does not capture instance) - https://github.com/klayoutmatthias/klayout/issues/48 (Cancel does not reset current tool) - https://github.com/klayoutmatthias/klayout/issues/51 (Segmentation fault on return to main window and other opportunities) - https://github.com/klayoutmatthias/klayout/issues/53 (Unreadable 'about' text) - https://github.com/klayoutmatthias/klayout/issues/62 (QXmlSimpleReader#parse cannot be called) - https://github.com/klayoutmatthias/klayout/issues/63 (Wrong output on DRC non_interacting with empty second input) - https://github.com/klayoutmatthias/klayout/issues/64 (Crash on exit) - https://github.com/klayoutmatthias/klayout/issues/68 (OASIS reader issue with degenerated shapes) - https://github.com/klayoutmatthias/klayout/issues/69 (DRC: 'inside' does not merge shapes of second input) - https://github.com/klayoutmatthias/klayout/issues/71 (Target cell argument is required) - https://github.com/klayoutmatthias/klayout/issues/72 (Edges/Region NOT issue) - https://github.com/klayoutmatthias/klayout/issues/73 (Allow 'change layers' on PCells which support a single layer parameter) - https://github.com/klayoutmatthias/klayout/issues/74 (Small-corner boolean issue) - https://github.com/klayoutmatthias/klayout/issues/75 (Python PCell issue when parameters are called 'layer') - https://github.com/klayoutmatthias/klayout/issues/79 (Replace function enabled also for read-only macros) * Further enhancements: see links - https://github.com/klayoutmatthias/klayout/issues/29 (Permissive mode for OASIS writer on odd-width paths) - https://github.com/klayoutmatthias/klayout/issues/59 (Async download of package index and details) - https://github.com/klayoutmatthias/klayout/issues/66 (Authentication dialog indicates retry) - https://github.com/klayoutmatthias/klayout/issues/77 (Layout#copy_tree now works in non-editable mode too) 0.25 (2017-11-04): * Enhancement: Menu customization Menu items can be disabled or enabled now. The former "Key Bindings" configuration page has been turned into "Menu Customization". Check boxes allow enabling or disabling of menu items. Disabled menu items are not shown. A search filter allows quick selection of menu items by title or path. * Enhancement: The cell tree no longer is collapsed on edits or when the sorting order changes. * Enhancement: Using a special menu path, macros can be configured to appear in submenus now. * Enhancement: KLAYOUT_HOME environment variable to control the location of the application folder. The application folder is the place where KLayout keeps the configuration, macros, packages and other things. * Enhancements: Major overhaul of the build environment - Qt5 supported now - Employs qmake as build system - Reorganisation of the sources - Continuous integration enabled (unit tests integrated in .pro files, JUnit output etc.) - Compatible with the clang compiler * Enhancements: Buddy tools: KLayout now comes with a set of additional executables that provide some functionality subset in a lean way. These binaries are named "strm..." and are installed along with KLayout. - strm2cif: converts any format to CIF - strm2dxf: converts any format to DXF - strm2gds: converts any format to GDS2 - strm2gdstxt: converts any format to GDS2/text - strm2oas: converts any format to OASIS - strm2txt: converts any format to plain text (internally) - strmclip: creates a clip from a file - strmcmp: compares two files (logically) - strmxor: compares two files (geometrically) For more information, use the "-h" or "--help" option. * Enhancements: HTTPS support for loading files from URL's directly * Enhancements: Numerous enhancements and optimizations in the RBA/pya area and in the debugger. * Enhancements: KLayout notifies the user when a file was changed and asks whether to reload. * Enhancements: "File cell or layer": type into the cell or layer list to jump to the cell name typed. * Enhancements: Advanced search features in the filter entry box for the cell selection form: Case sensitive/insensitive, glob pattern, clear button. * Enhancements: Tree expansion icons have a better contrast now on Windows with dark background. * Enhancements: Forward and backward navigation buttons in the main window. These buttons jump to the previous or next display state: zoom window, hierarchy depth, etc.. * Enhancements: A Package manager is provided. Packages are add-ons for KLayout and can include macros, script libraries, fonts for the TEXT PCell, technologies, DRC scripts etc. Packages can be published on GitHub or any server supporting WebDAV. After registering a package, users can install or update packages with a few clicks. For more information see https://github.com/klayoutmatthias/klayout/wiki or "About Packages" in the "Various Topics" area of the main documentation. The package manager is found in the "Tools" menu under "Manage Packages". * Enhancements: LEF/DEF reader: - Compatibility fixes with version 5.8 - Regions and Groups are supported now - LEF/DEF is a standare format now and can be used with "File/Open" for example. * Enhancement: DXR reader supports variable path widths now * Enhancement: XOR provides graphical progress * Enhancements: Libraries can be associated with a technology. Only libraries associated with the selected technology are shown in the selection dialog. * Enhancements: Overlapping instances are easier to select now (instance selection cycling). * Enhancements: Many more methods in RBA/pya. For example: - Ability to directly insert "D" types (such as DBox into layouts and cells. - RBA::RecursiveShapeIterator now supports complex (non-rectangular) search regions - A more consistent type framework (consistent complex transformation types, vectors) - More intuitive interface in certain objects (i.e. CellView, LayerPropertiesNode, Annotation etc.). Changing an attribute usually has an immediate effect on the respective property now ("live objects") - Hash functions for certain objects - Box, Edge, Trans, Polygon, and other objects can be used as dictionary keys now. - New import methods for Region, EdgePairs and Edges - New features for LayerMapping and CellMapping - Multiple selected cells in LayoutView - RBA::TextGenerator to supply the Basic.TEXT PCell's functionality as static feature - Receivers can be added to signals and removed from signals now. - Individual instance iterator for CellInstArray - ... * Enhancements: Enhanced layout statistics form with detailed shape statistics. * Enhancements: Line styles (dashed, dotted etc.) available now. Works best with manhattan layouts. * Enhancements: "Marked box mode": boxes are drawn with a cross. * Enhancements: Arbitrary pattern size for custom fill pattern (no limited to multiples of 8).

2017-04-08Updated cad/klayout to 0.24.10mef1-6/+6
------------------------------ (from: http://klayout.de/development.html) Version 0.24.10 Release date: 2017-04-01 Features: Enhancements: New method CellView#is_dirty? This method indicates that a cell view needs saving Bugfix: DEF reader was not able to read routing Routed segments with vias plus continued wiring were not read. Instead an error message was shown saying "Invalid orientation specification" Bugfix: Setting "technology-data" configuration property did not work Reading or writing the "technology-data" configuration property is the only way to access technology data from a script. Hence it's important that this property can be set. With this patch, "technology-data" can be set to an XML string which has the same format than the one stored within the configuration file. Bugfix: Reader issues with some RVE files The RVE reader could not read files with cell names containing hyphens (like "A-B"). Bugfix: Inplace operators are now working in Python too For example "r1 += r2" was not working (r1 and r2 are pya.Region objects for example).

----------------------------- From: http://klayout.de/development.html Release date: 2016-11-29 Enhancements: The RBA::Region#smooth function was enhanced to give somewhat better results Enhancements: DXF's circle approximation can now also specified through an "accuracy" parameter: if less than the number of specified points is required to achieve the given accuracy, the number is reduced accordingly. This also applies to the polygon interpolation of spline and arc curves. Enhancement: RBA integration now is compatible with Ruby 2.3 which allows building on Ubuntu 16 as well. Enhancement: OASIS files with instance angles >360 were rejected before. Now, this has turned into a warning. Bugfix: DEF reader was failing to read MASK/via combinations. Bugfix: The marker browser's "show only rules with errors" option was enabled again on sorting of errors. Bugfix: DRC: Using Layout objects for inputs didn't work Bugfix: Copying Hierarchy treets containing PCell's made the PCell's being turned into static cells.

2016-07-12Updated cad/klayout to 0.24.8mef1-5/+5
----------------------------- Version 0.24.8 Release date: 2016-06-19 - Bugfix: XOR and different or big database units: With tiling, XOR between two layouts with different database units was still not working correctly. Also, when the database unit was larger than 1nm, the XOR feature was dropping results sometimes when tiling was on. - Enhancements: progress bar shown also for "-z" mode scripts: The solution of 0.24.7 has been modified to avoid annoying progress bar windows popping up in background-window mode: Now, progress bar windows will only pop up if an active main window is present. This will enable progress bars for scripts that open their own main windows but still keep the application GUI-less when the script does not do so. - Bugfix: Crash on empty panel: When "New/Panel" is used a view without a layout is created. An attempt to create layout on such panels crashed the application. - Bugfix: LEF reader now can read PIN statements including VIA - Bugfix: Polygon smoothing was not working properly in some cases Previously the smoothing function was sometimes dropping vertexes from the polygons. Smoothing now does also guarantee not to exceed the given distance. - Bugfix: Sorting cells by area now sorts cells by name as second choice In the previous version, cells with identical area were grouped but the order was arbitrary. Now the name is used as the second-level sorting criterion which keeps such cells sorted by name.

-------------------------------------- http://www.klayout.de/development.html -------------------------------------- Release date: 2016-05-03 Features: - Bugfix: XOR and different database units: With tiling, XOR between two layouts with different database units was not working correctly. - Enhancements: progress bar shown also for "-z" mode scripts: Scripts running in KLayout with the "-z" option (don't show main window) were not experiencing progress reporting before. Now a small modal window is shown during long-running operations that indicates the progress and provides a Cancel button to abort the operation. - Bugfix: Crash on using "Edit/Make cell": This happened sometimes if the selected objects contained instances. - Bugfix: Invalid behavior of paths with reflecting segments: For example a path made of the points (0, 0), (0, 1000) and (0, 0) had a reflecting segment which cause some computations (for example the bounding box) to return invalid results.
2016-04-08update 0.24.5 to 0.24.6mef1-5/+5
http://www.klayout.de/development.html -------------------------------------------------------- Version 0.24.6 Release date: 2016-03-22 -------------------------------------------------------- - Bugfix: Early delete of plugin object when returning a new object from PluginFactory#create_plugin. The returned object was not held, so in Ruby the GC could destroy the object. This could lead to crashes in applications employing the Plugin API. - Bugfix: It was possible to edit read-only macros. For example, it was possible to enter new lines in macros marked as read-only. However, these changes were not saved. - Bugfix: Shift+Tab not working in macro editor. On some platforms, Shift+Tab was not working as expected. This key combinations was supposed to left-shift a selected block an undo indents. - Bugfix: Wrong scaling of layers when doing XOR's with layouts with different database units. This happened when the layouts had different layers and "summarize missing layers" was disabled. - Bugfix: "Search & Replace" was not working properly if named layers were present. Specifically the shape search was not working due to an incorrectly formed query. - Bugfix: Sizing produced incorrect results in case of slowly varying polygon contours. The effect was a contour with spiky distortions where two "almost parallel" edges connected. - Bugfix: The diff tool was not reporting differences correctly when layers were present in one layout while they were not present in the other. This happened specficially when "Summarize missing layers" was disabled. - Enhancement: New context mode in marker browser: "Current or Any". In this mode, the markers are displayed in the context of the current cell. If that is not possible because the markers are given for cells outside the cell tree of the current cell, the fallback is to show the markers in the current cell as in "Any" mode. - Enhancement: More consistent behaviour of cell and category filters in the marker browser. For example, the category filter is now also applied when selecting a node for a certain cell in the cell branch and if nested categories are present, the category filter is applied smarter - not just on each category. --------------------------------------------------------

Although a comparatively simple piece of software, a layout viewer is not only just a tool for the chip design engineer. Today design's complexity require not only a simple "viewer". Rather, a viewer is the microscope through which the engineer looks at the design. There are numerous viewers available, but sadly there are not many which satisfy a few basic requirements. Most of them are commercial and expensive. If there is need for a simple, yet powerful viewer - here it is.
