load_drc_results

load_drc_results(
    path, *, engine=None, max_results=None, timeout=None, show_progress=True
)

Read the results database of an earlier design rule check.

A KLayout database is read with KLayout, as drc_check reads the one it produces, so KLayout must be available. A Calibre ASCII database is read without Calibre.

Args

  • path (str | PathLike): Results database (.lyrdb for KLayout, ASCII .db for Calibre).
  • engine (str | None): Verification engine, "klayout" or "calibre". None uses config.default_drc_lvs_engine, and when that is unset the first engine found.
  • max_results (int | None): Load at most this many markers. A RuntimeWarning reports when markers are left out.
  • timeout (float | None): Seconds allowed for the engine run.
  • show_progress (bool): Show the elapsed time while the engine runs.

Returns

verification.DRCResults: Markers grouped by rule, with an empty log and exit_code 0.
