Power Delivery Network Pre-Layout Design Planning and Analysis Through Automated Scripting

Passive power delivery design has often been an afterthought in printed circuit board (PCB) and package design processes. Signal performance is frequently prioritized using the most optimal resources available to the design engineers. Based upon recent experience, the power delivery network (PDN) requirements for high performance compute (HPC) systems have evolved to a level of stringency that must be addressed through rigorous and purposeful design practice rivaling traditional high-speed signaling considerations. A pre-layout design planning process, using automated structure and parameter scripting, with corresponding AC and DC analyses in relevant power delivery networks, is presented here.
