Update May 11, 2012: With the release of SystemVue 2012.06 the *.ibs file is generated automatically

As you may know we have W1714 SystemVue AMI Modeling Kit to generate the AMI portion of an IBIS model (the *.ami file plus either *.dll on Windows or *.so on Linux) for Channel Simulation. But I often get questions on how to generate the analog part: *.ibs file itself. Or sometimes the question is about how to generate the analog part with no AMI for the traditional IBIS flow, based on SPICE-like transient. At present, Agilent doesn’t offer a solution in this space, but my customers tell me they do one of several things:

1. Follow the IBIS Cookbook http://www.vhdl.org/pub/ibis/cookbook/cookbook-v4.pdf or
2. Engage a consultant like Teraspeed http://www.teraspeed.com/ for a measurement-based model
3. Use a free tool s2ibis (SPICE to IBIS) http://iometh.com/Product/s2ibis3/index.html
4. Paid tool like SharkSim Developer http://sharksim.com/developer_features.html which is also uses a SPICE to IBIS appraoch

Hope this helps! Please leave a comment if you’d like share your method of generating *.ibs files.
