Hello Tim! You may try to simulate the B-model attached to a long line (e.g. TD=3D5ns). Put a big resistance at the end of the line (e.g. 1Gohm). In this experiment, you should see that the incident waveform is independent from Ccomp, while the reflections at the driver side strongly depends on it. Hope this helps, Luca On Tue, 7 May 2002 14:25:21 -0400 "Timothy Coyle" <Timothy.Coyle@xxxxxxx> wrote: > Hi, > I am trying to see the effects of different Ccomp values of an IBIS outpu= t=20 > buffer in HSPICE.
