Drc

class pyedb.workflows.drc.drc.Drc(edb: Edb)

Lightweight, high-accuracy DRC engine that runs inside an open PyEDB session.

The engine is thread-safe and uses an R-tree spatial index for scalable geometry queries. All rule checks are parallelised with concurrent.futures.ThreadPoolExecutor.

Parameters:

edbpyedb.Edb

Active EDB session (must already be open).

Examples

>>> edb = pyedb.Edb("my_board.aedb")
>>> rules = Rules.load("rules.json")
>>> drc = Drc(edb)
>>> violations = drc.check(rules)
>>> drc.to_ipc356a("review.ipc")

Methods

Drc.check(rules)	Run all rules and return a list of violations.
Drc.to_ipc356a(file_path)	Write a complete IPC-D-356A netlist plus DRC comments for fab review.
