System and method of analyzing distributed RC networks using non-uniform sampling of transfer functions

A system and method is described for the simulation of the transfer function of very large RC networks of IC chips, such as VLSI. Both the real and imaginary components of the transfer function of RC networks have a property of changing more rapidly at lower frequencies but changing less rapidly at higher frequencies. Methods are employed which interpolate between transfer functions of the RC network for specific frequencies in order to derive an interpolated transfer function of the RC network.
