DrcViolation

A single DRC violation.

Returned as part of a DrcResult after running run_drc(). Each violation describes a specific rule failure, including the rule name, affected layer(s), severity, and a bounding box around the offending geometry.

result = run_drc(cell, rules)
for v in result.violations:
    print(f"[{v.severity}] {v.rule_type} on {v.layer}: {v.message}")
