摘　　要：依据IEEE1149.1标准,采用SOPC技术设计了一款高速的边界扫描主控器;用户可对该主控器进行配置,输出测试所需的控制信号,输出的测试时钟TCK频率可达50MHz,大大提高了边界扫描测试效率;同时,开发的具有自主知识产权的边界扫描主控器IP核为SOPC系统可测性设计提供了一个很有实际价值的组件,无需专用边界扫描测试设备即可实现对系统的边界扫描测试功能;经时序仿真波形和数字示波器观测结果验证,该边界扫描主控器所产生的测试信号符合测试要求,设计正确合理。According to the IEEE Std 1149.1, a kind of high-speed Boundary-scan master controller is designed based on SOPC. This master could be configured by user, and offer the control signal for the test, the frequency of text clock TCK can reach 50Hz, which greatly improve the test efficiency of the boundary-scan-test. At the same time, the Boundary-scan controlling IP core that has own intellectual property provides a valuable module for SOPC system, it could achieve boundary-scan-test without special equipment. The simulation and experimental results have proved the design correct and rational, and are capable of processing boundary-scan test effectively.
