Modeling on Parallel Test System Based on Object-Oriented

Abstract

Compared to traditional sequence test, parallel test, which means multiple units-under-test (UUTs) can undergo testing simultaneously, can improve test throughput by increasing the number of test tasks in a period of given time, improve instrument usage by reducing idle time of CPU and instrument, save test cost by sharing expensive instrument and device. Built on general automatic test system, parallel test system belongs to complex test system. Associated with the traditional way, test and measurement are usually modeled with functional representations. But functional model is not a better representation for parallel test system because of its low level of abstraction. By raising the level of abstraction from the function-level to the object-level, object-oriented approaches focus on the real-world aspects of a system and provide a better model of parallel test system. The unified modeling language, or UML, is a third-generation object-oriented modeling language. And rational unified process (RUP), which is developed and maintained by Rational Software Corporation, is on the base of UML, and is a sort of modeling approach together with UML. In this paper, an object-oriented model of parallel test system will be built according to rational unified process (RUP). Accompanied RUP, a serial standardization analysis and design documents, which describe parallel test system in UML, will be produced. These documents can be contributed to engineering realization of parallel test system
