摘要
鉴于工程实践中对边界扫描技术的忽视，分析了它在实际使用中存在的误区，介绍了边界扫描接口的定义及其具体硬件结构，阐述了边界扫描的工作原理。并分析总结了其用于实际测试中的作用与优点，提出了对边界扫描测试进行优化时需要注意的方面．以利于更好地普及应用。
Because of the neglect of boundary scan technology in project practice, the misapprehension in practical use is analysed. The definition of boundary scan interface, it＇s hardware configuration and it＇s detailed working principle are introduced. Also introduced is the usage and advantage in practice use. In order to populize it better, the aspects of optimizing it are discussed.
