Test programming environment in a modular, open architecture test system

This work addresses two key concepts in device test program development: test class programming and pattern management. These are explored in the context of an open architecture test system, where the primary requirement is the flexibility to integrate externally developed capabilities into the system. Development against an open architecture test system includes the integration of software-based solutions (such as user-developed test classes) and third party hardware modules, including the software necessary to support the modules. This work focuses on the open architecture facets of test programming and pattern management, as embodied in the OPENSTAR™ specification. The software for Advantest Corporation´s T2000 system is used as a concrete example for highlighting these concepts.
