[IBIS-Users] s2ibis2 spectre issues

Hi,

I'm trying to generate an IBIS model for a standard 3-state buffer from a Spectre netlist for the first time. I've done it many times before using HSPICE. Spectre appears to not subtract the GND clamp from the pull-down curve correctly. The values I see in the .out files look reasonable, but it seems to be some issue with s2ibis creating the IBIS model. Has anyone seen this problem before? I'm running s2ibis2 V1.1 on unix. I also tried s2ibis2.sun4.fix v1.1 with no success. I'm unable to run s2ibis3 due to java issues.
