Static timing analysis method and static timing analysis system

Abstract

A static timing analysis method and a static timing analysis system are provided. The static timing analysis methods includes: obtaining a standard cell library file for describing a plurality of standard cells; performing topology mapping on the standard cell library file to find out a target sequential cell from the standard cells, in which the sequential cell includes a logic gate, a selection circuit and a register circuit; executing a logic test process to find out a pin combination that has a mutual non-controllable relationship, and removing timing constraints related to the pin combination that are taken as redundant timing constraints from the standard cell library file, so as to generate an optimized standard library file; and perform a static timing analysis on a target circuit design according to the optimized standard cell library file.
