Abstract
A method and system for reducing a number of paths to be analyzed in a multi-corner static timing analysis. An estimated upper slack variation based on a non-common path delay for a racing path is utilized in determining if a multi-corner static timing analysis may be bypassed for a racing path. In another example, an estimated maximum RSS credit based on a total delay for a racing path is utilized in determining if a multi-corner static timing analysis may be bypassed for a racing path.
