Extended CPM for system power integrity analysis

Power integrity (PI) co-analysis of Chip-package-system (CPS) is a powerful tool to accomplish the extremely challenging goal; lower cost but better performance. However, the conventional PI analysis of CPS using chip power model (CPM) has limitations on the design evaluation and optimization of board and package. In this paper, we demonstrate the limitation first and share our experience on the development of PI analysis flow using Extended CPM (ECPM) technique on CPS to overcome the limitation.
