IBIS is a standard for electronic behavioral specifications of integrated circuit input/output analog characteristics.
In order to enable an industry standard method to electronically transport IBIS modeling data between silicon vendors, simulation software vendors, and end customers, this template is proposed. The intention of this template is to specify a consistent format that can be parsed by software, allowing simulation vendors to derive models compatible with their own products.
IBIS Version 1.0 was first introduced in June, 1993. Work continued leading to IBIS Version 2.1 which has been formally ratified as ANSI/EIA-656 on December 13, 1995.IBIS Version 3.2, containing some technical extensions, has been released on August 20, 1999 and has been formally ratified as ANSI/EIA-656-A on September 21, 1999. This document became the official IBIS document forwarded to IEC (International Electrotechnical Commission) in the IEC 62014-1 ratification process (first started in September 1997). It was approved in December 1999 and has been voted for publication as an official international specification on April 13, 2001. IBIS 3.2 was renewed as ANSI/EIA-656-A on August 17, 2005.
IBIS Version 4.0 was ratified by the EIA IBIS Open Forum on July 19, 2002.
IBIS Version 4.1 was ratified by the EIA IBIS Open Forum on January 30, 2003. This version of the specification contains links to the IEEE VHDL-AMS and Accelera Verilog-AMS languages. It also enables links to Berkeley SPICE netlists.
IBIS Version 4.2 was ratified by the EIA IBS Open Forum on June 2, 2006. It was formally ratified as ANSI/EIA-656-B on September 1, 2006.
IBIS Committee Task Groups exist to address Quality issues, Cookbook creation, independent Model Review and Advanced Technology Modeling techniques.
The EIA IBIS Open Forum has also completed an Interconnect Model Specification (ICM) 1.0. ICM 1.0 was ratified on September 12, 2003. A revised version, ICM 1.1, was ratified July 15, 2005 and approved as ANSI/GEIA-STD-0001 on January 18, 2006. A free parser for ICM is available.
The committee is formally affiliated with EIA (Electronic Industries Alliance). It meets every three weeks on IBIS technical development, IBIS utilities development, IBIS parser/checker development, and for exchanging general information on good modeling practices and for dealing with all issues related to IBIS. The EIA/IBIS Open Forum also holds several IBIS Summit meetings worldwide throughout the year for face-to-face discussions and technical presentations.
IBIS models are widely available in company sites and under "Models" in the official EIA IBIS home page. Many model development utilities and much documentation is also available in the official EIA IBIS home page.
