基于信号完整性分析的高速PCB设计

在高速PCB设计过程中，仅仅依靠个人经验布线，往往存在巨大的局限性。介绍利用Cadence软件对高速PCB进行信号完整性仿真。结合以CycloneⅡ为核心的远距离无线通信系统控制模块的PCB设计，利用Cadence的SPEEC-TRAQuest，提取器件的IBIS模型，确定关键信号线的拓扑结构，做信号完整性仿真。依靠仿真结果指导设计和制作，极大地提高了电路设计质量，缩短了研发周期。本文主要介绍反射和串扰仿真。

High-speed PCB Design Based on Signal Integrity Analysis

In the designing process of high-speed PCB, if wire layout is only based on personal experience, there are usually huge limitations. This thesis presents the signal integrity simulation of high-speed PCB with the help of Cadence software. Combining the PCB design of the control module of the long-distance wireless communication system based on Cyclone II, using Cadence SPEECTRAQuest to extract the IBIS model of the devices and determine the topology of the key signal lines, simulation of the signal integrit...
