Abstract: A method for converting interconnect parasitics of an interconnect network into slew dependent pin capacitances utilizes charge matching between predetermined voltage thresholds. During timing abstraction of a macro, parasitics of interconnects connected to the primary inputs are represented as slew dependent pin capacitances in an abstract model being created. Interconnect model order reduction is employed to speed the process. The generated abstract is subsequently used in place of each occurrence of the macro during chip level hierarchical static timing analysis, leading to an enhanced accuracy of the timing analysis of the logic components driving the abstracts.

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.
