Abstract
Methods are disclosed for quantitatively characterizing the accuracy of a simulated electrical circuit model. In particular, available circuit simulation programs make use of 'black box' models of transmission lines used to carry high-speed electrical signals. Electrical transmission lines are characterized by resistance, inductance, capacitance, and dielectric conductance, all values of which may vary with frequency. The 'black box' model must accurately model the transmission line over a wide range of frequencies in a time-domain simulation. Algorithms used in the “black box” model may not accurately model the transmission line over the frequency range. Such inaccuracies must be quantified, and if excessive, must be corrected.
