Abstract

A corner prediction system applies data generated through discrete process, voltage, and temperature (PVT) corner prediction to achieve highly accurate continuous corner prediction coverage. Embodiments of the corner prediction system can be trained to generate accurate performance metric prediction for a continuous range of PVT corners within a design space given a set of available pre-trained PVT corners. The corner prediction system can address the need to provide accurate continuous timing prediction coverage of design operating conditions (represented by PVT corners) through the availability of discrete PVT corners.
