Glad to hear that. Also - there is a new FAQ page for S2IBIS3 that you and other users might find useful. It is available here: http://www.ece.ncsu.edu/erl/ibis/faq/S2IBIS3_FAQ.htm Thanks, --Ambrish Varma North Carolina State University ph(919)513-2015, fax(919)515-2285 _____ From: Dwayne Johnson [mailto:dwayne_j@gennum.com] Sent: Friday, July 14, 2006 12:03 PM To: 'Ambrish Varma' Subject: RE: [IBIS-Users] Using S2IBIS3 to generate ramp data You've already solved my problem!! I was using 1.0 and because of your reply, I now see that 1.1 is available and will fix this problem.

I'm starting to generate IBIS models using S2IBIS3 but I have a concern with the ramp data (dV/dt) that is calculated. The typ, min, and max spice files that are generated for this simulation includes the typical spice models for all 3 cases. So, although the input ramp time, temp and supply voltages are being varied for the dV/dt typ, min, max simulations, the spice models are not!!! I've looked at the source code in s2ispice.java and have confirmed that the min, max, and typ routines all specify typical models while varying temp, voltages, and input ramp times. I've looked in the spec but can't find anything to explain this. Shouldn't the spice models be varied for DV/dt ramp measurement, as they are in the rising/falling waveform case? Please advise.
