资源适配器接口是用于连接测试程序和仪器的软件接口,其目的是使实现测试系统程序开发的硬件无关性,在测试系统的开发中发挥着重要的作用。资源适配器接口的设计要求与自动测试系统的开发方法和软件的抽象层次密切相关,本文在完成对面向信号的自动测试系统RAI设计要求进行研究的基础上,利用IEEE 1641提供的信号、测试定义和XML的接口描述方法,完成对测试系统设计中需要的信号接口进行了描述。最后结合具体使用,给出了相关结论及该设计方法存在的不足和改进方法。
The resource adapter interface is a software interface for connecting test programs and instruments. The purpose of the resource adapter interface is to make the hardware independence of the development of the test system program important for the development of the test system. The design requirements of resource adapter interface is closely related to the development method and software abstraction level of automatic test system. Based on the research of RAI design requirements of signal-oriented automatic test system, this paper makes use of the signals provided by IEEE 1641, definition of test and XML interface description method to complete the design of the test signal interface required for the system were described. Finally, with the specific use, the relevant conclusions are given as well as the shortcomings and improvement methods of this design method.
