For signoff, the Cadence Encounter Timing System offers advanced waveform modeling and multi-valued SPEF for double-patterning RC extraction. Cadence QRC Extraction delivers a DPT-aware corners extraction technology that supports both LEF/DEF and GDSII flows. The Cadence Physical Verification System offers support of 20-nanometer double-patterning and incremental DRC correction, and TSMC rule decks are now available for the Physical Verification System. Encounter Power System provides accurate, basic and complex topology-dependent EM rules, and Litho Physical Analyzer and Litho Electrical Analyzer have been updated with 20-nanometer models for hotspot analysis and repair.
