摘　　要：首先介绍了嵌入式逻辑分析仪SignalTapⅡ的基本原理和操作流程,并结合实例详细说明了SignalTapⅡ在系统调试过程中的应用。使用SignalTapⅡ对系统进行调试,解决了器件管脚不够或不方便外挂测试工具等软硬件调试的困难,避开了电路板测试时连接器引起的信号完整性问题。实验结果表明,该方法大大减少了系统调试、验证时间,缩短了设计周期,提高了系统设计的灵活性。With the FPGA system design complexity increases,the traditional system debugging method can not meet their needs.This paper describes the basic principles and operating procedures of embedded logic analyzer SignalTapⅡ,with examples and detailed description of the SignalTapⅡ debugging process in the system application.Using SignalTapⅡ debug the system solved the hardware and software debug problems of the insufficient device pins or the inconvenient to plug testing tools and avoided the signal integrity caused by circuit board test connector.Experimental results show that the method greatly reduces the system debug,validation time and shorten the design cycle and improve the system design flexibility.
