摘要

IBIS模型广泛应用于I/O相关的信号完整性仿真。指出了现有IBIS模型在电力完整性相关仿真中存在的问题。介绍了在现有IBIS标准基础上增加一些附加信息以扩展其在SSN和其他电源完整性相关仿真中的能力的新建议。通过HSPICE中的一个示例说明了从晶体管级Spice模型中提取这些信息并在现有IBIS工具中实现新提议的过程。通过非理想电源的仿真验证了该模型的准确性

Enhancement of IBIS modeling capability in simutanous switching noise (SSN) and other power integrity related simulations - proposal, implementation, and validation

IBIS models are widely used in I/O related signal integrity simulations. This paper points out the problems with the present IBIS model in power integrity related simulations. A new proposal of adding some additional information to the existing IBIS standard to expand its capability in SSN and other power integrity related simulations are introduced. The processes to extract this information from transistor-level Spice model and implement the new proposal in existing IBIS tools are illustrated by using an example in HSPICE. The accuracy of the new proposed model is verified in simulations with nonideal power supply
