  • Publication number: 20120016652
    Abstract: Systems and methods related to fast simulation of power supply networks and identification of a set of extrema (e.g., maxima or minima) waveforms associated with the power supply networks. In accordance with an embodiment, a method is provided for simulating an electrical circuit, comprising preselecting an input vector file, initializing a supply voltage to a fixed value, performing event driven simulation using the input vector file, so as to extract time-varying power supply current waveforms at a plurality of power grid points. The method also comprises simulating a power grid using a linear network simulator or other SPICE type simulation tool, so as to derive time-varying voltage waveforms from the current waveforms for each point on the power grid.
