Abstract
A set of multi-corner multimode (MCMM) databases that correspond to a set of working scenarios are accessed. A full timing update on the set of MCMM databases, for the set of working scenarios, is applied. A graph based analysis (GBA) timing calibration is performed on the databases, for the set of working scenarios to obtain a set of GBA-calibrated databases. Multiphase optimizations on the set of GBA-calibrated databases are iteratively performed to generate a set of optimized databases, including: performing a phase-specific optimization on the set of GBA-calibrated database to obtain an improved set of databases, and recalibrating GBA timing on the set of improved databases prior to a next phase-specific optimization.
