MaxLinear and Calibre RealTime Digital: Signoff DRC in P&R
Adopting Calibre RealTime Digital for in-design AMS design rule checking verification speeds design closure
Automated design enhancements during P&R can create layout variances that lead to complex (DRC errors at the chip level, such as top-level/IP blocks interface, or “last mile” functional/timing ECO errors. The intricacy of these types of errors typically require P&R engineers to manually debug and correct during DRC closure. By enabling fast, iterative signoff DRC checking and fixing during floorplanning and placement, the Calibre RealTime Digital interface not only reduces batch DRC iterations, but also eliminates potential late-stage issues during final physical verification signoff that are exponentially harder to fix. Adopting the Calibre RealTime Digital interface enabled MaxLinear designers to accelerate their DRC closure and save weeks in their tapeout schedules for all designs at all nodes.
