本篇介绍了高速数字硬件电路设计中信号完整性在通常设计的影响。这包括特征阻抗控
制、终端匹配、电源和地平面、信号布线和串扰等问题。掌握这些知识，对一个数字电路设计者而言，可以在电路设计的早期，就注意到潜在可能的信号完整性问题，还可以帮助设计则在设计中尽量避免信号完整性对设计性能的影响。
As system clock frequencies and rise times increase, signal integrity design considerations are
becoming ever more important. Unfortunately many Digital Designers may not recognize the
importance of signal integrity issues and problems may not be identified until it is too late.
This paper presents the most common design issues affecting signal integrity in high-speed digital hardware design. These include impedance control, terminations, ground/power planes, signal routing and crosstalk. Armed with the knowledge presented here, a digital designer will be able to recognize potential signal integrity problems at the earliest design stage. Also, the designer will be able to apply techniques presented in this paper to prevent these issues affecting the performance of their design.
