Abstract
An integrated circuit design method, system and simulator, wherein the integrated circuit design method includes: determining a region in which power supply noise shall be analyzed; determining current model parameters of the region; determining model parameters of a power supply network model; inputting into a simulator a net list; judging whether or not the region satisfies noise requirements of a chip power supply; and if the region satisfies noise requirements of the chip power supply, determining that the initial area is a minimum area that satisfies the noise requirements of the chip power supply in case the initial number of decoupling capacitors are used in the region.
