Abstract
Computationally efficient methods of determining a transient supply current in a circuit are disclosed. The methods include offline simulation of circuit models to obtain time series of signal currents which are used in a dynamic simulation to calculate equivalent capacitances for a cell model of the circuit. The equivalent capacitances may be used in the simulation to compute estimates of noise current in a power distribution network.
