An open source software framework for the implementation of an open systems architecture, run-time system

This paper presents the outcome of a UK MoD sponsored development effort to provide a suite of source code that will be made available to contractors employed in the provision of test system software to the MoD and coalition partners. The primary purpose of this `open source software' is to provide a working test system software framework that meets the requirements of the MoD's DEFSTAN 66-31 [1] (Open Systems Architecture); in particular, the use of IEEE 1641 [2] and ATML [3]. Using the interfaces and data exchange formats defined by both IEEE 1641 and ATML, a software framework has been written to bring together COTS tools and test information, in an application that sees ATML Test Description through to UUT test pin. Specifically, the framework is broken down into the areas of: ATML Test Description Importer - Converting test requirements into a test program implementation carrying 1641 Test Procedure Language. 1641 Signal Translator - Mapping test signal requirements onto test resource capabilities (making use of ATML Test Station Description). Signal Routing - Connecting test resources to UUT pins. 1641 Test Signal Framework IDL Generator - Generating a run-time interface from 1641 signal libraries. 1641 Run-time - Implementing a 1641 runtime interface with calls to underlying test resources. COTS tools have been chosen from three different manufacturers, encompassing test program generation, test signal allocation and switch path routing. This project is known as the Open Systems Architecture Runtime System (OSA RTS).
