Enhancing IO Ring Checks For Consistent, Customizable Verification

Making sure IO rings comply with IP and SoC design rules.


The Calibre PERC IO ring checker framework eliminates manual checking by providing a robust DRC-like environment to verify all IO placement rules with sign-off quality. Running on the first LEF/DEF floorplan, the IO ring checker provides early and full coverage of IO ring placement rules, enabling changes with minimal impact on the layout. Fast, accurate debugging and correction ensures that SoC IO rings not only provide the needed protection, but comply with all IP and SoC design rules.
