Auto test system resource description method based on XML

摘要: 针对当前自动测试系统(ATS, Automatic Test System)信息共享和互操作能力差的问题,应用XML(eXlensible Markup Language)语言实现了ATS的模型化描述,模型化的信息包括测试设备、接口连接装置ICA(Interface Connector Assembly)、测试适配器和被测设备UUT(Unit Under Test).对测试设备的性能和UUT测试需求采用统一的信号与测试定义标准STD(signal and test definition)进行描述,实现了测试设备性能与UUT测试需求的自动匹配.通过引入逻辑资源的概念对测试设备性能与仪器通道之间的动态映射关系进行描述,以实现测试过程中仪器资源的合理分配.采用XML作为ATS的建模语言,提高了ATS资源建模的开发效率和系统内信息的互操作程度.Abstract: Aiming at the problems of information sharing and interoperability in ATS(automatic test system), XML(extensible markup language) was used for ATS modeling, including test equipment, ICA(interface connector assembly), test adapter and UUT(unit under test). Test equipment capabilities and UUT test requirements were described by unified STD(signal and test definition) standard, and automatically allocating available system resources to a given set of test requirements was achieved. Dynamic mapping relationships between test equipment capabilities and device physical ports were described by importing the concept of logical resource which is a logical entity that usually represents some internal capability of the instrument. The experimental result shows that adapting XML as ATS modeling language improves the development efficiency of ATS modeling and information interoperability degree.
