• Added check for permissions error while collecting child process memory statistics.

v0.11.2

Major:

• Updated sc-issue to generate self-contained testcases to allow for better sharing of testcases.
• Updated klayout tool driver to support map-file option for DEF-GDS export step, and remove need for hard coded options in .lyt file in favor of getting values from the schema.

Minor:

• Updated loading order to target in commandline interface to ensure schema parameers are set before loading target.
• Error checking for flowgraphs with duplicated edges.
• Added -ext to sc-show command to control what file is opened when multiple files are available.
• Tools:
  • OpenROAD - added flags to control antenna repairs: ['tool', 'openroad', 'task', 'route', 'var', 'ant_check'] and ['tool', 'openroad', 'task', 'route', 'var', 'ant_repair']; added clock buffer selection option from the library with ['library', lib, 'option', 'openroad_cts_clock_buffer']

v0.11.1

Major:

• Revamped documentation for better readability and navigability.

Minor:

• Fixed handling when loading schemas from JSON to ensure values are normalized correctly.
• When a tool fails, the last 10 lines of the log is printed when ['option', 'quiet'] is set to aid in debugging.
• Updated server/client to use python tarfile module instead of spawning subprocesses.
• Implemented python linting.
• Tools:
  • OpenROAD - implemented snapping to sites or manufacturing grid for component placement via ['tool', 'openroad', 'task', 'floorplan', 'var', 'ifp_snap_strategy'] and added ability to select SDC IO buffer for automatic constraint generation via ['tool', 'openroad', 'task', 'floorplan', 'var', 'sdc_buffer'].
  • yosys - fixed invalid keypath access when logiclib is incorrectly specified.

v0.11.0

Major:

• sc-issue added as command line application to support sharing runnable testcases.
• Removed the requirement that the initial task of the flowgraph be called 'import' and the final task be called 'export'.
• Fully implemented .node() to take in a task module, simplifying the construction of a flowgraph and removing its dependence on ['option', 'scpath'].

Minor:

• ['tool', tool, version, 'sbom'] added to be able to track a tools SBOM.
• .hash_files() updated to honor the 'hash' field for the file parameters.
• .calc_yield(), .calc_area(), .calc_dpw() updated to new schema parameters.

v0.10.2

Major:

• Support for Python 3.11
• Building arm64 wheels for surelog

Minor:

• Tools:
  • general - deployed docker based CI with automatic tool building and testing
  • klayout - support for OAS stream files via ['tool', 'klayout', 'task', 'export', 'var', 'stream'] = 'oas', better detection of missing layout cells
