Configuration method based on multipole method

Abstract

The invention provides a method for extracting and configuring resistance and inductance (RL) parameters based on a fast multipole method, which comprises following steps: proposing brand-new basis functions, dividing surface currents using centroid-midpoint basis functions, configuring an accurate impedance model, and proposing a brand-new method and preconditions for using FMM; the CM basis function introduced by the present invention can convert traditional vector bit integration operations based on edges into scalar bit integration operations based on surface elements, and the new integration calculation method is easier to operate and faster in calculation speed. The accurate impedance model enables the present invention to carry out broadband simulation from low frequency to high frequency; the corresponding use of FMM only needs to be based on the surface elements of edges. It is easier to configure the fast multipole method.
