摘要：

随着微电子技术的不断发展,在数字系统设计中系统工作频率不断增加,高速器件的使用越来越广泛。对信号进行完整性分析已经成为高速数字电路设计中的一个必要环节。针对高速数字电路设计存在的信号完整性反射噪声问题,首先从理论上分析了信号反射产生的原因及解决方法,然后以高速数字测试模块为例,利用Mentor Graphics公司的Hyperlynx软件进行仿真验证,以达到在设计阶段消除反射噪声的目的。

Abstract: With development of microelectronics and increase of working frequency of digital system. High speed devices have being used broadly. It is necessary to analysis signal integrity in designing high-speed digital circuit. This article discuss one of problems of signal integrity in designing high-speed digital cricuit-reflection noise. First,the article analysis the original of signal reflection and how to resolve it in theory,then proved it through simulation using Hyperlynx of Mentor Graphics corporation,in order to eliminate reflection noise in design phase.
