摘要

输入/输出缓冲信息规范(IBIS)模型广泛用于信号完整性分析,因为它们能够保护专有信息,并且与完整的SPICE模拟相比,可以减少仿真时间。本文研究了从典型数字缓冲器的全SPICE模型中生成具有I/V和V/T数据的IBIS模型。为了提供一种合适的方法,我们用完整的SPICE模型验证了几种不同的IBIS模型生成策略来合并包效应。此外,还对IBIS在HSPICE和ADS中的模拟精度进行了研究。

Evaluation of IBIS modelling techniques for signal integrity simulations without and with package parasitics
Input/Output Buffer Information Specification (IBIS) models are widely used in signal integrity analysis because of their ability to protect proprietary information and to reduce simulation time when compared to full SPICE simulations. Generation of IBIS models with I/V and V/T data from a full SPICE model of a typical digital buffer without and with package parasitics is investigated in this paper. Several different IBIS model generation strategies to incorporate package effects are validated with the full SPICE model in order to provide a suitable approach. In addition, the accuracy of IBIS simulations in HSPICE and ADS is investigated.
