Target is to reduce the properties repository to a singleton.
Hence, there is no need to translate property IDs and it
is possible to retrieve properties everywhere.
The OASIS reader is refactored to avoid property renaming
and change of property definitions per ID.
Now, the default of --subst-char in strm2oas is "don't substitute".
You can explicitly specify "don't substitute" using "--subst-char="
(without value).
The option is called "--lefdef-joined-paths" for strm* buddy tools
and "joined_paths" for pya/RBA.
Wires with multiple segments are combined into long paths when
possible - this fails on anisotropic widths and 45 degree segments.
* [CONSIDER MERGING] Clarification and typo fixed in DRC doc.
* Implemented #1097 (discourage file compression, use CBLOCK)
* A warning is printed if file compression is enabled on OASIS
* A hint is present in the writer options
* CBLOCK is default (with fresh config) and for buddy tools
(use --cblock=false to disable it)
* Strict mode is default too.
* Updated tests
* Implementated patch as suggested by issue-1047
* Implementing blend-mode for LEF/DEF for a first solution for issue-1048
* Added testcase, fixed other tests
* Issue-1050 fixed - now REGION, BLOCKAGE and DIEAREA are relevant from mapping file, nothing else
* Bug fixes
* Experimental: DEF multipart paths
* Experimental: ignore LEF wire extension, ignore PATTERNNAME
* Implemented PATTERNNAME in DEF instead of LEF ..
* Implemented nondefaultrule vias
* LEF/DEF: non-defaultrule vias need a name suffix.
* Refined solution for NDR via names, updated test data
* Updated test data
* Multiple map files and 'REGIONS FENCE' + 'REGIONS GUIDE' layer mapping entries.
* Added test data, updated doc.
* Some enhancements and feedback
REGIONS in map files -> REGION
REGION NONE for map files (maps REGIONs which are neither GUIDE or FENCE)
Bugfix: VIA with ORIGIN
No via cell name prefix by default for buddy tools
* Simplified buddy tool options for LEF/DEF property names
Dropped --lefdef-dont-produce-instance-names,
--lefdef-dont-produce-pin-names and --lefdef-dont-produce-net-names
options. Instead, these options have to be enabled by giving
the respective property names.
Writing the property names takes some space and these
options are simply confusing and redundant.
* Issue a warning about missing cut geometry for a DEF via with PATTERNNAME (which is ignored)
* Fixed issue-1065
- warning if a layer is not mapped
- "," allowed as separator between files on buddy tools (in addition to '+')
- relative paths are resolved relative to . in buddy tools (more natural on Linux)
- Fixed tl::warn and tl::error so warnings/error messages can be continued with tl::noendl.
The option is -m or --heal.
It is default off as in boundary cases (e.g. full layer vs. empty)
the healing adds a considerable memory and performance penalty.
Healing is only effective with tiling and affects output shapes
as well as shape counts.
