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.
Aiming at the problems of low flexibility and difficult reuse of core logic in the existing boundary scan test system based on compiled language, this paper proposes a method of writing test in Tcl scripting language based on the analysis of the characteristics and extension methods of Tcl scripting language. Script feasible method of boundary scan test.Through the boundary scan test-related operations packaged into Tcl extended commands, the use of script commands to achieve the purpose of controlling the boundary-scan test equipment.On the basis of the design to achieve the Tcl scripting language control boundary scan Test the prototype system.Through the experimental analysis, the feasibility of the method is verified.
