The Input/Output Buffer Information Specification (IBIS), also known as ANSI/EIA-656, has become widely accepted among electronic design automation (EDA) vendors, semiconductor vendors, and system designers as the format for digital electrical interface data. Because IBIS models do not reveal proprietary, internal processes, or architectural information, semiconductor vendors? support for IBIS continues to grow. IBIS models are one of the most important tools used to support TI customers. TI?s goal is to create IBIS models that are compatible with the latest IBIS specifications for every new logic part. This application report describes TI?s IBIS creation, validation, and distribution process, so that customers can be better informed about our IBIS models. This application report also discusses the accuracy of IBIS models provided by TI.
