to_ipc356a#

Drc.to_ipc356a(file_path: str) → None#

Write a complete IPC-D-356A netlist with DRC annotations.

This method exports the full netlist in IPC-D-356A format with all detected violations appended as comment lines. The file can be imported by CAM tools (Valor, Genesis, etc.) for fabrication review.

Parameters:
file_pathstr

Output file path. Overwrites existing files without warning.

Notes

  • File format follows IPC-D-356A specification

  • Violations are appended as comment lines starting with C

  • Includes netlist information (nets, primitives, padstack instances)

  • Compatible with major CAM software packages

Examples

>>> drc = Drc(edb)
>>> violations = drc.check(rules)
>>> drc.to_ipc356a("fab_review.ipc")

Export with violations:

>>> rules = Rules().add_min_line_width("trace", "3mil")
>>> drc = Drc(edb)
>>> drc.check(rules)
>>> drc.to_ipc356a("review_with_violations.ipc")
