摘要
针对实际PCB中网络间的串扰特点,建构三线耦合均匀传输线模型,借助信号完整性分析工具Hyperlynx进行PCB布线前LineSim的串扰仿真,仿真结果表明:增大线间距、减小介质厚度、加防护布线、一定范围内减小耦合长度和给攻击线、受害线端接合适的电阻都能减小串扰,降低串扰引起的噪音,改善信号完整性问题,合理的使用多种方法可有效解决串扰噪音。
In view of the actual network of PCB between erosstalk, to construct a three line coupled- transmission model, with the signal integrity analysis tools Hyperlynx for PCB wiring LineSim before the crosstalk simulation, the simulation results show that the spacing, reducing medium thickness, add protection wiring, and a certain range reduced coupling length and to attack line, suffer line termination appropriate resistance can reduce crosstalk, reduce cresstalk noise caused, improve the signal integrity problems, reasonable use several methods can effectively solve the crosstalk noise.
