Abstract: Methods, systems and media for simulating or analyzing voltage drops in a power distribution network can use an iterative approach to define a portion of a design around a victim to capture a sufficient collection of aggressors that cause appreciable voltage drop on the victim. This approach can be both computationally efficient and accurate and can limit the size of the data used in simulating dynamic voltage drops in the power distribution network.

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.
