Shared timing graph propagation for multi-mode multi-corner static timing analysis

Abstract:

According to certain aspects, the present embodiments include techniques for performing a single timing analysis run for a plurality of views representing different modes and/or corners. An embodiment analyzes and maintains relevant timing information that is different for different views, but otherwise maintains the same information for all views. This allows each individual view in a single run to be analyzed in the same manner as separate runs for each separate view, thereby ensuring the same QoR. These and other embodiments provide substantial savings in runtime and memory consumption over other approaches.
