IBIS (Input/Output Buffer Information Specification) is a behavioral model in ASCII file format that describes the input/output characteristics of a device. The IBIS specification provides a way for I/V and V/T data of a device to be used in simulators for signal integrity analysis.
The IBIS specification was developed so that semiconductor manufacturers could provide models of their devices with fast simulation times, multi platform support, and without sharing intellectual property (circuit design and process), such as the case with SPICE models. Since an IBIS file is a behavioral model, it also has the benefit of simulating at much faster times than a SPICE model file.
The IBIS specification is a recognized standard, ANSI/EIA-656A. The IBIS Open Forum (an EIA group) is responsible for the official IBIS specification. The IBIS Open Forum meets every three weeks to discuss current issues and future enhancements of the IBIS specification and related modeling issues.
