摘　　要：针对现有基于编译型语言开发的边界扫描测试系统灵活性较低、核心逻辑复用困难的问题,在深入分析了Tcl脚本语言特点和扩展方法的基础上,提出一种用Tcl脚本语言编写测试脚本实现边界扫描测试的可行方法.通过将边界扫描测试相关操作封装成Tcl扩展命令,实现了使用脚本命令控制边界扫描测试设备的目的.以此为基础,设计实现了Tcl脚本语言控制的边界扫描测试原型系统.通过实验分析,验证了该方法的可行性.The flexibility of Boundary-Scan Test system which developed by compiled language is poor and it is difficult to reuse the core logic. In order to solve these problems, First, the features and extended methods of tool command language （ Tcl ） were analysed thoroughly. Then, a feasible method was proposed, which is used to implement Boundary-Scan Test by Tcl scripting language. By defining operation of Boundary-Scan Test as extended commands of Tcl, the goal to control Boundary-Scan Test device by using script command was realized. On the basis of this method, a prototype of Boundary-Scan Test system developed by Tcl was designed and imlalemented. Finally. the feasibilitv of this method was verified by experiental results.
