Research on the Resource Management in ATS

Abstract

The test task of ATS generally needs various test resources for its completion. One main task of TPS runtime system in the ATS software is to find out the matching test resources for every specific test task and the reasonable coincidence relations between Test/ Excitation channels. The ATS software development method based on signal-oriented is an approach to resolve the problem. The interchangeability of instruments, the portability of software and the interoperability of the systems are the goals pursued in the design of nowadays ATS software. In this ATS software background, how to manage effectively the test resources of the system, especially how to satisfy the demand of multitask in parallel test system for the test resources optimizing allocation is a key point for the design of ATS software. Therefore, the paper puts forward a dynamic test resource management method that is based on the resource lifecycle manager. At the same time according to the model of ATS test resource capability that is signal-oriented, the method of resource matching based on the extraction of the keywords is put forward. As for the demand of multitask in parallel test system for the test resources, the resource allocation method based on the generalized resource load is brought forward. The resource management methods brought forward not only enable the rapid matching of the test resources to be achieved effectively but also can realize the portability of test software and the interchangeability of instruments.
