Automated DRC Voltage Annotation Provides Faster And More Accurate Verification For Voltage-Aware Spacing Rules

How to improve confidence in signoff, regardless of complexity.


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