Abstract :
In this paper, we show that it is necessary to include the distributed effects of the power grid to accurately model the power supply noise for high frequency microprocessors. We show that high frequency resonances can be entirely missed if such effects are not modeled. Finally we prove the theory with experimental validation on the 90 nm Pentium® 4 microprocessor.
