Formulation and Network Model Reduction for Analysis of the Power Distribution Network in a Production-Level Multilayered Printed Circuit Board
A methodology for modeling the power delivery network from the voltage regulator module to the pins of a high pin count integrated circuit on a printed circuit board (PCB) is presented. The proposed model is based on inductance extraction from first principle formulation of a cavity formed by parallel metal planes. Circuit reduction is used to practically realize the model for a production level, complex, multilayer PCBs. The lumped element model is compatible with SPICE-type simulators. The resulting model has a relatively simple circuit topology. The model is corroborated with microprobing measurements up to a few gigahertz. The model can be used for a wide range of geometry variations in a power integrity analysis, including complex power/ground stack up, various numbers of decoupling capacitors with arbitrary locations, numerous IC power pins and IC power/ground return via layouts, as well as hundreds of ground return vias.
