Abstract:
1. A computer system comprising: a first computer portion structured and/or programmed to receive input characteristics of a transmission line to be simulated as a distributed resistance-capacitance (RC) interconnect, with the input characteristics being sufficient to define a transfer function for the simulated RC interconnect; and a second computer portion structured and/or programmed to determine at least one pole of the transfer function such that the transfer function is not truncated in the determination of the at least one pole; wherein: the transmission line has negligible inductance and is simulated as an RC interconnect; the input characteristics comprise interconnect resistance (R), interconnect capacitance (C), driver resistance (R the transfer function is given by the following equation: H(s)=1/(1+Aθ the second computer portion determines the at least one pole by transforming the denominator of the transfer function into terms of a variable x, finding at least one value for x such that the transformed denominator is equal to zero and using the at least one value for x to determine the at least one pole of the transfer function; and the at least one pole of the transfer function is solved in terms of variable x as:
