摘要: 提出可重构测试接口适配器(RTUA)的思想,用户通过程控接口可以现场自动配置RTUA以满足不同UUT及不同信号的测试需求。采用匹配函数描述测试点与仪器端口的匹配程度,匹配函数综合了测点信号属性与仪器性能参数、仪器可靠性、仪器成本等因素。给出RTUA的硬件架构模型,控制模块采用SOPC技术实现,可调用不同的配置文件实现RTUA重构。给出RTUA的软件设计方法,采用COM组件实现测控计算机对RTUA的配置管理。

Abstract: This paper proposes a thought of Reconfigurable Test Unit Adapter(RTUA). RTUA can be configured in real-time with programmable interface to satisfy the test requirements of different UUTs or signals. A kind of matching function is presented to describe the matching degree between test point and instrument port. Matching function integrates signal properties of test point, capability parameters of instrument and instrument’s price and so on. Hardware architecture of RTUA is put forward. Control module is implemented with SOPC and can be configured with different configuration files. Software design method of RTUA is given, test and control computer realizes the configuration management of RTUA with COM.

Key words: Automatic Test System(ATS), Test Unit Adapter(TUA), switch network, SOPC
