The Calibre Auto-Waivers tool significantly reduces debug time, without the risk of accidentally waiving true design rule errors. The solution accurately accounts for waivers across cell hierarchies without placing a significant burden on the user.
The Calibre Auto-Waivers tool permanently saves waivers and their associated text to a specific geometry layer, providing a standardized, consistent waiver record. This waiver record not only enables automated waiver removal during DRC, but also enables historical waiver analysis across designs and processes.
The Calibre Auto-Waivers tool implements waiver management automatically during a Calibre nmDRC run, without any need to modify foundry rule files.
The Calibre Auto-Waivers engine is hierarchically invariant, so even if violations for a specific cell are promoted up or pushed down in the hierarchy, the Calibre Auto-Waivers process can still waive the results correctly.
