Bases: bag.verification.base.SubProcessChecker, abc.ABC

the base Checker class for Virtuoso.

This class implement layout/schematic export and import procedures.

Parameters:

  • tmp_dir (str) – temporary directory to save files in.

  • root_dir (Dict[str, str]) – dictionary of root run directories.

  • template (Dict[str, str]) – dictionary of SVRF jinja template files.

  • env_vars (Dict[str, Dict[str, str]]) – dictionary of environment variables.

  • params (Dict[str, Dict[str, Any]]) – dictionary of default flow parameters.

  • max_workers (int) – maximum number of sub-processes BAG can launch.

  • source_added_file (str) – the Calibre source.added file location. Environment variable is supported. If empty (default), this is not configured.

  • import_ref_lib (str) – the import reference libraries list file location. Environment variable is supported. If empty (default), this is not configured.

  • cancel_timeout_ms (int) – cancel timeout in milliseconds.

  • enable_color (bool) – True to enable coloring in GDS export.
