1.4. Simulation with IBIS Models
Because of their behavioral nature, IBIS models do not have to include any information about the internal circuit design of the I/O buffer. Most component manufacturers, including Intel, provide IBIS models for free download and use in signal integrity analysis simulation tools. You can download generic device family IBIS models from the Intel website for early design simulation or use the IBIS Writer to create custom IBIS models for your existing design.
