Stochastic Analysis Method for Tree-Type PDNs on Mixed-Signal PCB

Abstract

In this paper, a stochastic analysis method is proposed for extraction and evaluation of power distribution map (PDM) in system printed circuit board (PCB). This is conducted based on some system-level information including placement and routing geometry, power distribution network (PDN), component package parasitic, and voltage regulator module (VRM). A simple model for power consumption of major constituent blocks of the system, is analytically extracted based on circuit parameters. Verifications are conducted by a specific designed and fabricated board. The proposed approach can be considered as a preliminary verification step of the PCB design flow. In addition, it helps to have a basic consideration about system layout performance.
