1.4. Simulation with IBIS Models

IBIS models provide a way to run accurate signal integrity simulations quickly. IBIS models describe the behavior of I/O buffers with voltage-current and voltage-time data curves.

Because of their behavioral nature, IBIS models do not have to include any information about the internal circuit design of the I/O buffer. Intel provides free IBIS models for use with Intel FPGA designs in signal integrity analysis simulation tools. You can obtain and customize these models for signal integrity design simulation.
