| 摘 要： | 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。

| Abstract: | 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 reasonable degree. |

| Keywords: | signal integrity crosstalk hyperlynx global simulation |
