摘要
本文研究了SOC高速数字集成电路测试用Loadboard信号完整性(SI)的问题。提出了一种基于Hyperlynx软件平台对Loadboard信号完整性进行建模和仿真的方法,研究了元件封装、布线长度、层叠设置、特征阻抗等参数的变化对高频信号产生的影响,从而分析出保证Loadboard电路板SI的设计方法。
This paper studies the signal integrity (SI) issues in the loadboard which is used for high-speed digital integrated circuit testing. We propose a modeling and simulation method for Loardboard SI in hyperlynx. We also study the im- pacts on high-speed signals when the component package, trace length, stackup settings, characteris- tic impedance and other parameters change, and analyze the methods to ensure the SI of the load- board.
