Integration of functional analysis and common path pessimism removal in static timing analysis

A method, system, and computer program product to integrate functional analysis and common path pessimism removal (CPPR) in static timing analysis include determining initial path slack for a path for a given timing analysis test. The method also includes comparing the initial path slack with a threshold value to determine if the path passes or fails the given timing analysis test, and based on the path failing the given timing analysis test, performing the functional analysis on the path only based on performing the CPPR on the path, or performing the CPPR on the path only based on a result of performing the functional analysis on the path.
