Evaluating Green's functions for modeling multilayer integrated circuits

A computer-readable medium that stores a computer program that causes a computer to execute instructions for modeling an integrated circuit, wherein the computer program includes instructions for:

• specifying a layout for the integrated circuit, wherein the layout includes a plurality of devices arranged in a plurality of layers and a plurality of connections between the layers;
• specifying locations for a source point and an observation point for the integrated circuit;
• determining a plurality of static images for the source point and the observation point;
• determining a plurality of discrete complex images for the source point and the observation point;
• determining a Green's-function value for the source point and the observation point by combining the static images and the discrete complex images;
• and
• saving at least some values based on the Green's-function value.
