What's new in this version: 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.
Fixed: - Fixed an issue with QByteArray/QVariant transformation in Qt binding - PCB gerber import: Incorrect handling of D02 operations. - Proper handling of comments in RVE DB reader - Bug in the "smooth" function - Deep mode DRC: separation from "inside" gives wrong errors - Internal error on net extraction
Enhancement: - LVS could not do "connect_implicit" with global nets - Plain transformation of cell missing - RBA/PYA: Provide event when a net is selected in the netlist browser - True support for text objects in DRC/LVS (text layers) - Edges#extents, Texts#extents and EdgePairs#extents now work hierarchically in deep mode. In DRC, this means, "extents" is a deep-enabled method now - Image handling enhancements - Enhanced API for ObjectInstPath - Difficult to select specific labels for net name assignment in net extraction. Solution involves a more elaborate handling of texts through "text layers - A separate search range can be specified for box selections now - Technology specific libraries: library name resolution based on technology - Controlling the way a layout reader integrates cells into an existing layout
