Model and analysis for combined package and on-chip power grid simulation

We present new modeling and simulation techniques to improve the accuracy and efficiency of transient analysis of large power distribution grids. These include an accurate model for the inherent decoupling capacitance of non-switching devices, as well as a statistical switching current model for the switching devices. Moreover, three new simulation techniques are presented for problem size-reduction and speed-up. Results of application of these techniques on three PowerPC/sup TM/ microprocessors are also presented.
