Abstract

This paper discusses a novel methodology for optimization of design parameters for power integrity analysis. In the proposed methodology, Plackett-Burman Design of Experiment (PB-DoE) is utilized to determine the impact of design parameters on the response parameters. The design parameters are optimized to improve the dc voltage drop and dc current density. The impedance profile is compared for nominal and optimized design from 100MHz to 200MHz the obtained results are validated for thermal and noise performances. With this methodology, about 33% reduction is obtained in the dc drop voltage and dc current density with about 1% to 5% improvement in thermal performance.
