摘要
传输线上的信号反射是造成过冲、振铃等信号完整性问题的主要原因,为解决高速信号传输过程中的反射问题,采用HyperLynx软件仿真分析反射端接技术。利用HyperLynx软件的前仿真工具Line Sim建立传输线模型,进行了源端串行端接、简单并行端接、主动并行端接、戴维南端接和并行RC端接等形式的源端端接匹配和终端端接匹配研究。仿真验证结果表明,端接技术可以有效抑制传输线上的反射噪声,改善高速电路的性能。
Signal reflection in transmission line is the main cause of signal integrity issues such as overshoot, ringing, etc. Based on solving the refleotion problem in the process of high speed signal transmission , the paper uses the HyperLynx software of simulation tool Line Sim to establish the model of transmission line and carries on various termination matching studies, such as source end serial termination, simple parallel termination, active parallel termination, Thevenin termina- tion, parallel RC termination and other forms of source end termination and terminal termination. The simulation results show that the termination technique can suppress the reflection noise on a transmission line and improve the performance of high - speed circuits.
