IBIS-AMI models allow signal integrity engineers to simulate millions of bits within minutes but are also based on a specific set of assumptions. Understanding the fundamental assumptions behind IBIS-AMI models and the different components of an IBIS-AMI model is key to using these models to obtain accurate simulation results. This tutorial starts with those fundamental assumptions, discusses the different parts of an IBIS-AMI model and how they are used. Common problems with AMI models are discussed along with how users can identify them.


Basic understanding of IBIS-AMI models: how they are put together, how they work and how to apply them to system design problems. Attendees will understand the different parts of an IBIS-AMI model, how they are used during simulation and how to interpret the results of Statistical and Time-Domain AMI simulations.

Intended Audience

Basic understanding of signal integrity and time-domain circuit simulation (SPICE). Basic understanding of S-Parameters and how they represent circuit behavior. Experience running IBIS-AMI models in EDA simulators is useful but not required.
