Circuit Verification with Calibre®

Calibre's circuit verification strategies and tools effectively and efficiently address the reliability and functional yield challenges of today's advanced and complex IC designs.


Circuit Verification involves several essential steps in the design process that will help identify potential circuit or design errors as well as extract the necessary data for downstream circuit simulation. During this step, layout is analyzed and compared vs. the schematic to ensure design integrity. Second, the design is analyzed for short-term and long-term electrical failures and, if found, those are presented to the designer for fixing. And finally, a detailed silicon model is constructed with intentional device, advanced parameters, and parasitic information into a format that consumed by a downstream simulator so that designers can reliably determine if their design is meeting electrical specifications (timing, power, etc.)

“Calibre offers a unique combination of performance, accuracy, and capability allowing us to implement an optimal recipe for our 0.095 micron process. Calibre is already in use with our 0.180 and 0.150 micron technologies, and NEC is aggressively moving forward with advanced semiconductor processes. Calibre is a key enabler in accelerating this schedule.”
