Abstract :
In this paper, we present an empirical approach for the validation of the power supply impedance model. The model is widely used to design the power delivery for high performance systems. For this purpose, several silicon wafers of the Pentium/sup /spl reg// III and Pentium/sup /spl reg// 4 processors were built with various amount of decoupling. The measured data showed significant discrepancies with the model predictions and provided useful insights in investigating the model regions of validity.
