PPA (performance, power, area) is the objectives pursued by IC design teams, TAI system not only does high-speed analysis of all performance indicators, but also helps users to achieve PPA goals better and faster.For example, with artificial intelligence technology, deep learning has brought about epochal change, enabling expert experience to be automatically reproduced. Combining software engineering and IC technology, TAI system creatively integrates advanced technologies into the technical framework of signoff analysis to bring high value optimization results to users.
