Claim One:
1. A computer modeling system comprising: a processor that has at least one input that receives parameters related to one or more electrical transmission lines, the parameters representing one or more physical characteristics and one or more electrical characteristics of the one or more electrical transmission lines; a database with a set of one or more macromodels that in which the processor is arranged to apply the parameters in a simulation to determine an electrical behavior of one or more of the electrical transmission lines, wherein the applied parameters comprise at least one of at least one parameter that varies according to frequency and at least one parameter that is input as a matrix; and an automatic selection process controlled by the processor that selects a macromodel from the set of macromodels to simulate one or more of the electrical transmission lines, the selection of the macromodel being determined by one of comparing a total distortion to an error threshold, wherein the processor provides a generated transmission line macromodel corresponding to the selected macromodel to an electrical circuit simulator program.
