Achieving accuracy and high performance in static sensitizable path analysis

In this paper we propose the use of reconvergence analysis to boost the performance of static timing analyzers. The method is based on a reconvergence analysis on top of an hierarchical analysis. The proposed analysis is especially useful for analyzing large circuits containing a lot of unsensitizable (false) paths, where an hierarchical approach is not sufficient in itself. An example of the efficiency of the approach is given.
