Abstract
This disclosure describes methods, systems and media for analyzing voltage drops in a power delivery network in a simulated design of an electrical circuit. In one embodiment, a system determines, for a victim element ('victim'), a voltage drop caused by each aggressor element ('aggressor') in a set of aggressors in the design and creates a data structure that includes, for each victim, at least one of: (1) each voltage drop caused by each aggressor in the set of aggressors or (2) a sum of the voltage drops on the victim caused by all of the aggressors in the set of aggressors. The system can then compute a set of simulations based on random inputs to generate a distribution of possible voltage drops for each victim using data in the data structure.
