IBIS - What is an IBIS model (as opposed to a SPICE model)?

Description

What is an IBIS model (as opposed to a SPICE model)?

解决方案

IBIS (Input Output Buffer Information Specification) is a method of providing the Input/Output device characteristics through V/I data without disclosing any circuit/process information. It can be thought of as a behavioral modeling specification suitable for transmission line simulation of digital systems, and it is applicable to most digital components.

Xilinx provides IBIS models instead of SPICE models because SPICE models contain proprietary information. However, Xilinx does provide some HSPICE and Eldo Models for high-speed modeling of I/Os (Virtex-6, Virtex-5, Virtex-4, and Virtex-II Pro).
