OSA-RTS INTRODUCTION

4


• The Open System Architecture Runtime System (OSA-RTS) provides a common framework of shared ATS components that implement ATML solutions for translating Test Descriptions and Test Equipment Descriptions into “run-able” test programs.

• The current OSA-RTS framework has been designed for the C, C++ and C# textual programming languages and extended to the graphical programming environments:

• LabWindows / CVI

• LabVIEW

• TPL (using project selected carrier language)


5



Open Systems Architecture

• IEEE 1641

• IEEE 1671 (ATML).

Open Source Software

– Available to contractors employed in

the provision of test system software to the UK MoD & partners.

The OSA-RTS architecture migrates ATML Test Descriptions (IEEE Std 1671.1), (utilizing IEEE Std 1641 signals), into run-able code using TestStand sequences, CVI Code Modules or LabVIEW test VI’s utilising a 1641 Run-time interface which makes calls to underlying test resources.

• ATML Test Description Importer (LabVIEW or LabWindows/CVI):• Converts ATML test requirements into a test program implementation carrying 1641 Test Procedure

Language.

• 1641 Signal Translator• Maps test signal requirements onto test resource capabilities (making use of ATML Test Station

Description).

• Signal Routing• Connects test resources to UUT pins.

• 1641 Test Signal Framework IDL Generator• Generates a run-time interface from 1641 signal libraries.

• 1641 Run-time (LabVIEW or LabWindows/CVI):• Implements a 1641 runtime interface with calls to underlying test resources.

OSA-RTS TEST STATION RESOURCES

27


Test Station Description

1.The Test Station Description is an XML file with associated schema (IEEE 1671.6) , that is used to describe the Test Resources and their Capabilities for an ATE.

2.The OSA-RTS uses the Test Station Description to assign/allocate test resource capabilities to test signals ATML operations.


1.The Capability Driver Description is an XML file with associated schema, that is used to generate Template Driver Code calls to the runtime system.

2.In the OSA-RTS ATML example, the Template Driver Code is targeted specifically to LabWindows/CVI, but is also utilised by the TPL demonstration.

3.The template code is inserted into the CVISrcFile.c by the 1641 Signal Translator.

4.The Capability Driver Description file is currently generated manually.

• Driver element used without Member element.

• Supports non-OO paradigm.• Note that CVI example is not object orientated.

• Supplements ATML Capabilities (e.g. Test Station Description) to describe the native driver actions needed to implement each capability.

• In this case, used to describe the TSFs provided by the 1641 Runtime.

OSA-RTS DEMONSTRATION EXAMPLES

32


• The OSA-RTS examples contained in this demonstration take a single ATML TPS and show how it may be utilised in 3 different development and runtime environments:

• LabWindows/CVI and TestStand

• LabVIEW and TestStand

• TPL using a carrier language (C language through LabWindows/CVI) as a standalone executable


33


• The following are provided for each example

• Instructions for processing the ATML TPS through each of their applicable OSA-RTS components

• Any further instructions that may be required for building and/or runtime implementation

• Instructions for execution of the final built test program

• How to determine if the demonstration has run and how to obtain the runtime trace actions and compare them to their expected performances
