What is IBIS-AMI?

IBIS-AMI (Input/Output Buffer Information Specification - Algorithmic Modeling Interface) is a standard used for simulating the behavior of high-speed digital interfaces. It allows chip vendors to provide models of their I/O buffers without revealing proprietary design information. These models are used by system designers to simulate signal integrity and timing performance of high-speed links, such as those found in DDR memory, SerDes, and backplanes, predicting the behavior of digital signals transmitted through channels and interconnects, addressing signal degradation effects like reflections, crosstalk, and attenuation.
