面向信号的自动测试系统结构设计

Design of ATS structure based on Signal-Oriented Method

文章研究了面向信号的自动测试系统分层结构设计,提出了在自动测试系统开发中基于广域测试环境的自动测试系统结构开发方法。通过研究方法在信号模型中的具体使用,表明标准提供的测试描述规范、基本信号库和XML接口有助于分层结构中各层的功能实现,满足测试系统设计要求。最后同时提出了方法在实际运用中存在的一些缺陷。

This paper presents an architecture of ATS based on layered structure and Signal-Oriented Method,then mainly researches on how to combine the IEEE 1641 standard with the layered structure according to ABBET in ATS development method. The implement in Signal-Oriented ATS based on IVI-Signal model draws a conclusion that the signal and test definitions,library of basic signal classes and XML interface can fulfill the functional requirement of layers in this architecture and the method can achieve the goal of ATS design. Finally,some deficiencies of this method in practice are offered.
