摘　　要：在高速数字电路中,电信号串扰是影响信号完整性的一个主要因素。针对近端电信号串扰噪声和远端电信号串扰噪声进行理论建模,借助信号完整性仿真工具HyperLynx进行仿真分析,研究攻击线与受害线的间距、耦合长度、信号线到参考平面的介质层厚度、信号上升沿及下降沿速率对于电信号串扰的影响。仿真结果表明:合理的设计可以有效抑制电信号串扰,进而提高电路信号完整性。In high-speed digital circuits,electrical signal crosstalk is one of the main factors affecting signal integrity.The theoretical model of the near end electrical signal crosstalk noise and the far end electrical signal crosstalk noise is established in this paper,and some parameters affecting electrical signal crosstalk are simulated by using the signal integrity simulation tool HyperLynx,such as the distance between aggressor line and victim line,the coupling length,the thickness of dielectric layer from the signal line to reference plane and the rates of rising as well as falling edges of signals.The simulation results show that the reasonable design can effectively suppress the electrical signal crosstalk and improve the signal integrity of the circuit.
