Abstract:
Examples of techniques for statistical static timing analysis of an integrated circuit are disclosed. In one example according to aspects of the present disclosure, a computer-implemented method is provided. The method comprises performing an initial statistical static timing analysis of the integrated circuit to create a parameterized model of the integrated circuit for a plurality of paths using a plurality of timing corners to calculate a timing value for each of the plurality of paths, each of the plurality of timing corners representing a set of timing performance parameters. The method further comprises determining at least one worst timing corner from the parameterized model for each of the plurality of paths based on the initial statistical static timing analysis and calculated timing value for each of the plurality of paths. The method also comprises performing a subsequent analysis of the integrated circuit using the at least one worst timing corner.

Claim (Index 1):
A computer-implemented method for statistical static timing analysis of an integrated circuit, the method comprising:\n specifying, by a user, a criteria for paths and tests for the integrated circuit; performing, by a processor, a statistical static timing analysis for each of the paths of the integrated circuit to create slack canonicals; projecting, by the processor, the slack canonicals for each of the paths of the integrated circuit to a worst value; applying a filter to the slack canonicals; determining, by the processor, worst timing corners; performing a selection based on the worst timing corners; and delivering a timing setup to an optimization tool, the timing setup being based at least in part on the selection.
