Abstract:

Method, system, and computer readable medium are disclosed for analyzing electrical properties of a circuit. The method may comprise: providing a network model including at least one network parameter, the network parameter being defined over a frequency range; converting the network parameter into an intermediate network parameter having first and second portions; identifying first and second frequencies defining a frequency sub-range; replacing the first portion of the intermediate network parameter with a DC value when a frequency associated with the intermediate network parameter is lower than the first frequency; replacing the first portion of the intermediate network parameter with a transitional value when the frequency associated with the intermediate network parameter is within the frequency sub-range; and converting the intermediate network parameter with the replaced first portion into an updated network parameter.
