A method and apparatus for generating a noise circuit model for an electronic circuit includes analyzing the electronic circuit to determine a first circuit parameter for a victim and aggressor circuits and a second circuit parameter for the aggressor circuits, ordering the aggressor circuits based on their first and second circuit parameters, setting a current model parameter of the circuit model to an initial value, selecting a first aggressor circuit, determining whether to reduce the selected aggressor circuit into a virtual attacker model based on its first circuit parameter, updating the current model parameter in accordance with either the selected aggressor circuit or its virtual attacker model to be inserted, inserting either the selected aggressor circuit or its virtual attacker model to the circuit model, for each aggressor circuit.
