Input/output Buffer Information Specification (IBIS) is a specification of a method for integrated circuit vendors to provide information about the input/output buffers of their product to their prospective customers without revealing the intellectual property of their implementation and without requiring proprietary encryption keys.
IBIS-AMI support statistical and so-called time-domain channel simulations, and three types of IC model ("impulse-only," "GetWave-only," and "dual mode") Intel initiated IBIS in the early 1990s.
[2] Intel needed to have all of its divisions to present a common standardized model format to its external customers.
This prompted Intel to solicit EDA vendors to participate in the development of a common model format.
[9][10] Upon its purchase of the standards program of TechAmerica in July 2013, SAE International became the parent of IBIS Open Forum.
Changes included an IBIS‐AMI extension for mid-channel repeaters, new parameters for jitter and noise in IBIS-AMI, and analog buffer modeling improvements.
[16] Work on enhancing the specification can be tracked in the work-in-progress section of the IBIS Open Forum website.
