摘要
IEEE1149.7标准相对于IEEE1149.1标准新增了很多测试与调试的功能,解决了现今复杂度高的芯片和系统无法测试的问题.在深入地研究IEEE1149.1和IEEE1149.7两种标准的基础上,利用自上而下的设计方法完成了由IEEE1149.1信号变为IEEE1149.7信号转换器的设计,在QuartusⅡ平台中通过Verilog语言实现,将设计应用在FPGA中,并用QuartusⅡ中嵌入式逻辑分析仪SignalTapⅡ采集FPGA的输出信号.输出结果表明所设计的方案可以将IEEE1149.1信号转化为IEEE1149.7信号,可用于IEEE1149.7的待测系统进行测试与调试.
IEEE1149. 7 standard with respect to the IEEE1149. 1 standard added a lot of testing and debugging features, to solve the problem of high complexity of today＇s chips and systems can＇t be tested. In-depth research foundation IEEEl149. 1 and IEEEl149. 7 two standards on the use of top-down design method to complete the conversion by the IEEEl149. 1 IEEEl149.7 converter design in Quartus Ⅱ platform by Verilog language the design in FPGA, and SignalTap Ⅱ embedded logic analyzer capture FPGA output signal in Quartus Ⅱ. The output results show that the design of the program can transform IEEEl149. 1 signal into IEEEl149. 7 signal that can be used IEEEl149. 7 test system for testing and debugging.
