Summary:A method of, and a system for, determining an extreme value of a voltage dependent parameter of an integrated circuit design is provided. The method includes determining a plurality of current waveforms, each of the plurality of waveforms corresponding to one of a plurality of aggressor objects in the design of the integrated circuit; applying each of the plurality of current waveforms to a subset of the plurality of power bus nodes, the subset of the plurality of power bus nodes being designed to supply power to a corresponding one of the plurality of aggressor objects; determining a plurality of voltage waveforms, each of the plurality of voltage waveforms being at one of the plurality of power bus nodes and corresponding to one of the plurality of current waveforms; using the plurality of voltage waveforms to determine the extreme value.
