摘　　要：为克服传统测试方法在测试数字电路板时的技术障碍,提出基于弹上总线及边界扫描的弹上设备机内自测试设计方案。在介绍IM总线(module test and maintenance bus,TM Bus)和边界扫描的基础上,论述系统测试性设计的基本概念,搭建测试试验系统,并对系统测试性设计概念和主要考核指标进行演示、验证。结果表明:该设计能简化导弹的测试流程,提高导弹武器系统的可靠性、维修性和测试性。To overcome the technology barriers of the traditional test method in testing digital circuit board, put forwards a new design scheme of missile equipment built-in self-testing based on missile data bus and boundary scan. Discuss the basic concept of system testing by introduce of the module test and maintenance bus （TM Bus） and boundary scan. A test system is designed to illustrate the concept and test the main indicators of design for testability （DFT）. Performance testing indicates that the design can simplify testing process and improve the reliability, maintainability and testability of missile weapon system.
