Abstract

An approach for covering multiple selective timing corners in a single statistical timing run is described. In one embodiment, a single statistical timing analysis is run on the full parameter space that covers unlimited process parameters/environment conditions. Results from the statistical timing analysis are projected for selected corners. Timing closure is performed on the corners having the worst slacks.
