Methods, systems and media for simulating or analyzing voltage drops in a power distribution network can use an incremental 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, and then an incremental simulation of just the portion can be performed rather than computing simulated voltage drops across the entire design. This approach can be both computationally efficient and can limit the size of the data used in simulating dynamic voltage drops in the power distribution network. Multiple different portions can be simulated separately in separate processing cores or elements. In one embodiment, a system can provide options of user selected constraints for the simulation to provide better accuracy or use less memory. Better accuracy will normally use a larger set of aggressors for each victim at the expense of using more memory.
