A computer system for simulating performance of transmission lines, such as on-chip interconnects. The simulation uses direct extraction of poles, in contrast to conventional methods using poles obtained by a truncated transfer function. Using the directly extracted poles, far end response characteristic(s) can be determined to thereby aid in design of circuits using transmission lines. The far end response characteristic(s) that may be determined based on the directly extracted poles include, but are not necessarily limited to, frequency dependent effects, step response, ramp response, delay, 50% delay, rise time, 10% to 90% rise time, overshoot and normalized overshoot. A CAE tool designer and/or CAE tool user may decide how many pole pairs to directly extract to achieve a desired balance between computation resources required and resulting precision in the determination of far end response characteristic(s).
