IBIS to SPICE converter (370K v1.4 posted 10/98). This free 1.4 version of IBIS2SPICE supports models up to IBIS 2.0 version.
Support through version 3.2 available in many Intusoft simulation products or as a standalone product click here for more info.

The IBIS to Spice converter generates SPICE models from IBIS data sheet files. It reads a subcircuit template file (template.mdl) to define the SPICE subcircuit topology to be generated. The subcircuit template is customizable by the user. The default template contains subcircuit structures for use with IsSpice4. The program extracts the relevant data from the IBIS file and parses it into the SPICE subcircuit topology. The software has the ability to generate SPICE models from any or all of the IBIS models in an IBIS data sheet, for typical, best, and/or worst case speeds.

The zip file contains IBIS2SPICE.* (program files), IBIST#.DWG (ICAP/4 test circuits and schematics), *.LIB/*.IBS (sample IBIS data sheet and generate model library file), sample copyright.txt file, and template.mdl (subcircuit library template structure).

To install the converter, simply unzip the file. The IBIS2SPICE.Exe, *.Hlp, *.Mdl, and *.Txt files can be placed in any directory. No other setup is necessary.
