The purpose of this application report is to present the flow, the environment settings and TI requirements used to perform the analysis of critical power nets of a platform using an application processor. The Power Delivery Network (PDN) performance is measured by extracting and analyzing three printed circuit board (PCB) parameters: DC resistivity, capacitor loop inductance, and broadband target impedance. To conclude each parameter section, PDN extraction results of the AM572x General-Purpose Evaluation Module (GP EVM) processor board with some general layout recommendations are presented.
