Efficient Parametric Assessment of Worst-Case Voltage Droop in Power Delivery Networks

Power Delivery Network (PDN) optimization is crucial for guaranteeing adequate power integrity performance in modern microprocessor systems. In this work, we introduce a novel surrogate modeling workflow for efficiently predicting the worst-case voltage droop occurring at the loading points of a PDN including a set of free design parameters. We apply the proposed approach for modeling the impact of a set of decoupling capacitors on the performance of a template PDN structure.
