Abstract:
Systems, apparatus, and methods of static timing analysis for an integrated circuit design in the presence of noise are disclosed. The integrated circuit design may be partitioned into a plurality of circuit stages. A timing graph including timing arcs is constructed to represent the timing delays in circuit stages of the integrated circuit design. A model of each circuit stage may be formed including a model of a victim driver, an aggressor driver, a victim receiver, and a victim net and an aggressor net coupled together. For each timing arc in the timing graph, full timing delays may be computed for the timing arcs in each circuit stage.
