The accuracy of voltage-aware DRC is needed to achieve the high reliability and high yield that contribute to market success. By leveraging the power of Calibre® PERC™ packaged checks and automated text annotation in conjunction with the Calibre nmDRC platform, designers can run voltage-aware DRC checks with confidence in the results, regardless of design complexity or process node.

Automated voltage annotation lets engineers run voltage-aware DRC checks with Calibre confidence, regardless of IC design complexity or process node.

Accurate and repeatable reliability verification is now essential for both advanced node designs and the increasingly complex products being produced at established nodes. To ensure compliance with all process, reliability, and power management requirements, voltage-aware DRC applies variable spacing requirements, based on either the absolute voltage or delta voltage values, to accurately evaluate the required spacing between geometries The Calibre PERC automated text generation and verification flow provides all necessary design annotations, as well as guidance to help engineers fix inaccurate or conflicting voltage information, to ensure a successful sign-off DRC run with fast turnaround time for voltage-aware spacing rules.
