0.30.3 (2025-08-05):
|
||||
* Enhancement: %GITHUB%/issues/2044 Different combination modes on strm2xxx tools (+ and ,)
|
||||
* Bugfix: %GITHUB%/issues/2073 Klayout fails to read CELLNAME S_CELL_OFFSET property on Windows on big files
|
||||
* Bugfix: %GITHUB%/issues/2075 strm2oas ignores def net routing wire extensions
|
||||
* Bugfix: %GITHUB%/issues/2081 strm2oas a.oas,c.oas o.oas coredumps
|
||||
* Bugfix: %GITHUB%/issues/2087 DRC: Poor fill with skew step vectors (see more fill-related topics below)
|
||||
* Bugfix: %GITHUB%/issues/2088 Fixed a use case that generated duplicate OASIS cell IDs
|
||||
* Bugfix: %GITHUB%/issues/2094 Performance issue in the python code to insert Regions into Shapes
|
||||
* Bugfix: %GITHUB%/issues/2100 RNetExtractor extracts wrong RNode locations with tesselation
|
||||
* Bugfix: %GITHUB%/issues/2102 RNetExtractor internal error
|
||||
* Bugfix: Fixed automatic execution of scripts after package installation
|
||||
Now, restarting KLayout after package installation may not be needed
|
||||
* Bugfix: File watcher dropped file after is was temporarily removed
|
||||
* Bugfix: After deleting terminals from devices, reading old L2N/LVSDB files
|
||||
made these terminal re-appear in the netlist browser.
|
||||
* Enhancement: primary and secondary device parameters are separated in
|
||||
the LVS netlist view, so it is easier to see which parameters are relevant
|
||||
* Bugfix: Avoid a crash when reading OASIS files with broken code tables
|
||||
in OASIS CBLOCKs
|
||||
* Enhancement: New Ruby/Python functions: Macro#current and Macro attributes
|
||||
(Macro#get_attribute, Macro#has_attribute, Macro#set_attribute, Macro#delete_attribute)
|
||||
These features allow passing values in and out from a macro in other ways
|
||||
than defining global variables and basically allow parameterized macros.
|
||||
* Enhancement: Convenience function ObjectInstPath#cell
|
||||
* Bugfix: Some layout queries did not render the correct path_dtrans
|
||||
* Bugfix: "tap" feature
|
||||
- was not selecting shapes that fully overlap the view
|
||||
- texts are not considered as detecting them requires potentially search a large area
|
||||
* Bugfix: Fixed a TODO from old issue #1470
|
||||
* Enhancement: DRC function "def_output": A simple yet useful extension to obtain
|
||||
the output layout and to manipulate it (within limits)
|
||||
* Bugfixes and enhancements: fill feature (see also issue #2087)
|
||||
- tiles in tiled mode most not overlap when the origin is not global as tiles may use different origins
|
||||
- more efficient computation of remaining fill area
|
||||
- fill pattern "margin" feature simplifies keeping distance to other fill
|
||||
shapes or original features in multi-fill scenarios
|
||||
- fixed MT issues when using the fill feature in tiled mode with multiple threads
|
||||
- better compression of fill cell instances into arrays
|
||||
* Enhancement: Ruby/Polygon methods set_properties and clear_properties for Cell, Layout, Shape and Instance
|
||||
* Enhancement: a bunch of features that utilize expressions on polygons and other shapes
|
||||
to attach properties, filter base on properties or compute values in properties
|
||||
(aka "measurement features")
|
||||
- PolygonFilterBase#expression_filter (to be used in Region#filter and Region#filtered)
|
||||
can be used to filter polygons based on KLayout expressions, including properties
|
||||
- PolygonPropertiesExpressions object (to be used in Region#process and Region#processed)
|
||||
can be used to attach properties based on KLayout expressions, including other properties
|
||||
- Same for Edges, EdgePairs and Texts
|
||||
* Enhancement: handling of properties in shape merge in Region
|
||||
- Region#join_properties_on_merge controls how properties and handled during shape merge
|
||||
- New respective arguments in Region#merge, Region#merged
|
||||
- New layer methods "merge_props" and "merged_props" in DRC (allows joining properties
|
||||
from same shapes on different layers)
|
||||
* Enhancement: net property evaluation using KLayout expressions.
|
||||
Allows implementing more complex antenna rule checking schemes for example.
|
||||
- Ruby/Python: LayoutToNetlist#evaluate_nets
|
||||
- DRC: evaluate_nets
|
||||
|
||||
0.30.2 (2025-05-29):
|
||||
* Enhancement: %GITHUB%/issues/2016 Lazy evaluation of PCell also when changing guiding shape properties
|
||||
* Enhancement: %GITHUB%/issues/2041 strm2oas should read --lefdef-lefs and --lefdef-lef-layouts only once
