摘　　要：随着计算机速度的显著提高,信号完整性问题已经成为高速计算机设计中的关键。本文详细介绍了一种新的信号完整性分析技术,通过集成泰克公司逻辑分析仪和数字荧光示波器,将物理层模拟信号,数据层数字信号时间相关的联合观测,可以有效定位,分析高速计算机系统中出现的故障问题,排除由于信号完整性问题导致的计算机系统错误。最后结合MC68340的处理器和高速总线。给出了高速信号完整性分析实例。As computer signal rates climb dramatically,signal integrity problem has become the major challenge in high speed computer design. A new signal integrity analysis technology is described in this paper. It helps designer locate and debug signal integrity problems in high speed computer system. To integrate the digital storage oscilloscope with logical analyzer , it displays time-correlated views of both digital and analog waveforms on the same display. In the end it provides examples of how to debug signal integrity problems in high speed bus and MC68340 microprocessor.
