Calibre Auto-Waivers


The Calibre Auto-Waivers tool provides fast, accurate, automated recognition, removal, and tracking of waived design rule violations during DRC. It eliminates costly time and effort from the verification process and also ensures accurate processing of all waiver information on every DRC run.

Key features

Automated Waiver Removal During Calibre nmDRC Runs

The Calibre Auto-Waivers tool significantly reduces debug time, without the risk of accidentally waiving true design rule errors. The Calibre Auto-Waivers solution accurately accounts for waivers across cell hierarchies without placing a significant burden on the user.

Automated Waiver Analysis Across Designs and Processes

The 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.

No Need for Foundry Rule File Modification

The Calibre Auto-Waivers tool implements waiver management automatically during a Calibre nmDRC run, without any need to modify foundry rule files.

Promoted Cell Results Are Still Waived

Is hierarchically invariant, so even if violations for a specific cell are promoted up or pushed down in the hierarchy, the Auto-Waivers process can still waive the results correctly.
