Abstract
A linear circuit simulator can be supplied with a linear power distribution model of an integrated circuit (IC) and two sets of voltage regulator equivalent resistances. The linear circuit simulator can then be used to calculate two voltages, at a sense point of the IC, corresponding to the two sets of voltage regulator equivalent resistances. The two sets of voltage regulator equivalent resistances and the two voltages at the IC sense point can be used to interpolate a slope of a resistance versus voltage curve of the linear power distribution model. The slope can be used to calculate an updated set of voltage regulator equivalent resistances, which can be used by the linear circuit simulator to calculate a set of performance metrics and an updated voltage at the sense point of the IC.
