1. A method for evaluating a power distribution network for an integrated circuit, the circuit comprising at least a plurality of wires, a plurality of switches, and a plurality of power supplies, the method comprising the steps of: creating a circuit model of the circuit by representing each of the plurality of wires with at least a wire element, representing each of the plurality of switches with a switch element, said circuit model defining a plurality of nodes between connected elements; and performing a DC circuit analysis on said circuit model by simulating supply of DC power from the plurality of power supplies to said circuit model, and determining the voltage drop at at least a portion of said plurality of nodes of said circuit model.
