Description
Summary:The simulation and the analysis of a power distribution network (PDN), termed power integrity (PI), is performed in the frequency domain and primarily involves analyzing the power and ground planes, the decoupling capacitors and the simultaneous switching noise (SSN). The original layout is modified based on these PI analyses to account for any design flaws arising due to parasitic effects. To avoid an expensive procedure, it is add an additional simulation at the pre-layout stage to catch the major design flaws. These simulations are used to guide the final layout process. There are several commercial tools available to simulate a power distribution network. The goal is to develop a Matlab tool to perform about same functions as the commercial tools do, so it can be used to identify problems prior layout.
