Method to perform full accuracy hierarchical block level timing analysis with parameterized chip level contexts

Abstract:

A method and apparatus for on chip variation path-based pessimism reduction and improving analysis of a hierarchical integrated circuit design in an electrical circuit. The circuit has one or more block circuit levels and a top circuit level. The method in one embodiment comprises characterizing the top circuit level to produce a context function, the context function used by the block circuit level for evaluation.
