Abstract :
An analysis tool is introduced that measures subcircuit coupling and error attenuation in waveform relaxation (WR) circuit simulation algorithms with full dimensionality. Unlike current methods that use heuristics to calculate scalar gains, this method capture all the effects of error attenuation over time and space. An example is provided of how this technique can be used to study the performance of various partitions, schedules, and WR algorithms on a wide range of technologies, including BiCMOS.<>
