摘要
利用IBIS 模型进行板级信号完整性分析是一种简单、易用的分析方法。结合PCB 设计的SI 模型,介绍了几种板级信号完整性分析的方法,讨论了各种分析方法的利弊,确定了使用IBIS模型进行信号完整性分析和EMC分析。通过加载IBIS 模型对P4 主板的DDR 信号线进行了仿真,并对仿真结果进行了分析,达到了验证设计规范的目的。
Board level signal integrity analysis using IBIS model is a kind of simple and easy method. With the aid of the SI models, several methods are presented to analyze the signal integrity. The advantages and disadvantages of all methods are discussed, and IBIS model is selected to the board level signal integrity analysis and EMC analysis. The DDR signals of P4 mainboard are simulated by using IBIS model. At last, analysising simulation results testify the design specification.
