随着系统时钟频率大幅攀升，保证高速电路的正常工作成为设计的首要任务。PCB板作为信号载体，高速数字信号的完整传输是其设计的重要指标。文中从电磁场理论出发，分析串扰的成因和解决方案，并利用Hyperlynx软件对某型PCB进行全局和串扰仿真验证。通过不同端接方案仿真对比，选择最佳方案将串扰减小到合理范围。

With the development of electronic technology, the first priority for designers is to ensure normal working of high speed circuits. As a signal transmission carrier, the integral transmission of high speed digital signal on PCB board becomes a important indicator of the design. This paper analyzes the reason for and solution of crosstalk by the electromagnetic theory and tests the theory via global and crosstalk simulation of a PCB board. A comparison is made of different termination techniques and the best scheme is selected to decrease crosstalk to a rea- sonable degree.
