Open Source Software for OSA-Runtime
The UK MoD has sponsored the development of 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 Def Stan 66-31 (Open Systems Architecture), and in particular, the use of IEEE 1641 and ATML.
About the Open Source Software
Using the interfaces and data exchange formats defined by both IEEE 1641 and ATML, a software framework has been created to bring together COTS tools and test information in an application that covers ATML Test Description through to UUT test pin.
This framework includes the following major areas:
- 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 Routeing – 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.
Each of these manufacturers has participated in the standards’ development and their products have been developed to comply with those standards, thus ensuring their interoperability.
Open Systems Architecture Runtime System Overview
Note thatsince the software language requirements of the MoD’s Open Systems Architecture have been fully complied with.
As a consequence, the open source software that has been written to binds these COTS tools & data exchange formats is readily
useable by test station developers, and may easily be built upon to create a fully integrated test solution that complies with all
the MOD's requirements of the MoD test equipment policies and requirements.
