Mohamad,
What I do with any time domain simulator is to run tests with a
progressively decreasing time step (spatial resolution) and compare the
results. Generally there is a resolution beyond which there is no
significant increase in accuracy, and no significant change in the
resulting waveforms. Once I know that point, I then back off the
simulator resolution to a point where there is faster performance with
acceptable resolution.
regards,
Scott
