DESIGNrev DFM Interactive MDP nmDRC nmLVS Parasitic-Extraction PERC RET/OPC RVE SVRFencrypt TVF WORKbench xACT-3D xRC Calibre 2014.1_17.12 Mentor's IC verification and sign-off includes not only traditional rule-based physical verification and parasitic extraction, but also new capabilities and automated technologies that help improve yield by enhancing the design itself. Calibre® is the overwhelming market share leader and the industry standard for IC physical verification, due to the outstanding performance, accuracy and reliability of Calibre products. Over the last two years, Calibre nmDRC™ has reduced average DRC runtime by a factor of five, while Calibre's innovative Hyperscaling and MTFlex™ technologies have cut memory requirements in half. Calibre nmDRC also reduced overall cycle time with incremental DRC, which allows designers to make DRC runs in parallel. As DRC violations are reported, designers can immediately fix and recheck just the affected areas, while the initial DRC run continues. To handle complex and multi-variate, multi-dimensional checks that are not adequately addressed by traditional design rules, Calibre nmDRC's equation-based DRC (eqDRC) capability enables designers to express design rule checks as continuous, multi-dimensional functions that accurately and precisely reflect underlying physical interactions. With eqDRC, designers can use Calibre nmDRC to address complex DFM issues that other DRC tools simply can't handle. Calibre nmLVS provides actual device geometry measurement, programmable electrical rule checking, and sophisticated interactive debugging capabilities to ensure accurate circuit verification and further improve the designer's productivity.
