Abstract： The pursuit of performance，power and area (PPA) has become the consensus of IC chip design, especially the development to advanced process nodes. PPA has become a crucial metric of overall performance of IC design. Especially for the modules cloned numerous times in large-scale SoC chips, the pursuit of PPA becomes more extreme. This document describes how to improve the PPA optimization solution based on the Genus and Cerebrus tools of Cadence and the optimization of the Synthesis and the Back-End PR stage. The final result shows that, under the convergence of timing and DRC, employing the Cerebrus tool compared to Innovus can reduce power by 3.5% and area by 3.1%. Furthermore, utilizing the Genus+Innovus flow can reduce power by 6.4% and area by 8.5%, significantly decreasing chip area and power.
