This release is a fully backward compatible upgrade to the rev 1.1 specification released last year (Press Release dated Oct. 12, 1993). This improved and refined standard adds support for ECL, dual-supply buffers, ground bounce due to shared power rails, differential I/O, termination components, controlled rise-time buffers, much more complete package descriptions, improved open-side device modeling (open drain, etc.) and reference waveforms. These enhancements are a result of more EDA companies supporting the IBIS specification and feedback of those using rev 1.1 models. The IBIS Open Forum has created a version 2.1 of the "golden parser" that checks model syntax for comformance to the specification. It is currently being Beta tested. When completed, the parser will be made freely available in object code format IBIS is a consistent software parsable format that semiconductor vendors can use to specify the analog characteristics of input and output buffers. This essential information is readily transformed into accurate models by end users and simulation tool vendors. The resulting behavioral models enable users to perform high-speed, accurate signal-integrity simulations of their digital system interconnects. The IBIS Version 2.1 specification was developed through the cooperative efforts of simulator vendors and semiconductor companies who together comprise the IBIS Open Forum (see the attached roster). For More Information For more information about the IBIS Open Forum, send an e-mail request to ibis-info@vhdl.org. All of the documents and publicly available models are currently accessible via the public repository of VHDL International's Internet based machine (vhdl.org, 198.31.14.3, http://vhdl.org/). WWW, Gopher, FTP and Telnet "Anonymous", and "guest" dial-in access, (415) 335-0110, are all available.

Box 1443, M/S 631 Houston, TX 77251 Support: TI has a three-pronged attack on IBIS support. TI is working on a scheme to automatically generate IBIS models from TI Spice simulations (TI's proprietary Spice dialect), on an automatic means to generate C code to be linked in to TI Spice as a User Defined Element from an IBIS model, and an automatic means to create the Spice equivalent of the IBIS model from the IBIS model specification. The latter method differs from the second in that it uses skeletonized Spice primitive elements in the form of a subcircuit, while the second actually generates C code and compiles it for dynamic linking.
