Abstract
A method of analyzing the power distribution in a chip containing one or more voltage islands, each voltage island having a power distribution network connected to a chip-level power distribution network by one or more voltage translation interface circuits. The method comprising: analyzing the voltage-island power distribution networks independently of the chip-level power distribution network to obtain voltage translation interface circuit currents; using the voltage translation interface circuit currents as input to a model of the chip-level power distribution network to obtain voltage translation interface circuit input voltages; and calculating voltage translation interface circuit output voltages based on the voltage translation interface circuit input voltages, the voltage translation interface circuit currents, and current-voltage characteristics of the voltage translation interface circuits.
