This presentation provides an overview of how various tools, including

National Instruments (NI) TestStand, LabWindows CVI, LabVIEW, DSI

eXpress and Spherea newWaveX can be integrated to support the UK

MoD’s ATML Open COTS Solution Architecture (OSA).

Included is an insight into the OSA-RTS (Open Source Run Time

Software).

This integrates ATML Test Description with TestStand (and other tools),

on a variety of Hardware Abstraction Layer (HAL) implementations, to

provide a TPS process for creating and running test programs using

ATML standards with IEEE1641 compatible Signal Descriptions.

ATML Open COTS Solution Architecture

What is an OSA ATS?

• OSA - Open Systems Architecture - comprises

– Reference Model showing typical ATS components and key interfaces

– Set of standards required to satisfy each interface

• Reference Model - for visualising interfaces

• Standardised interfaces allows interoperability

• Not essential to use all interfaces identified…

– … but those used must be compliant

• MoD OSA similar to DoD ATS Framework

Why are these standards needed?

• Provides system independent test definitions

– Portable between compliant systems

– Simplifies re-host when ATS reaches end-of-life

• Facilitates information transfer

– Common information exchange format using XML

– Simplifies exchange of test & diagnostic information

– Results saved in common format but may be printed or displayed in any required style.

Benefits

• A standard XML exchange format for

sharing information between ATS

components

• Supports test program, test asset and

UUT interoperability

• System and TPS

interoperability

• TPS portability

• Simplified re-host

• Clearer understanding of ATS

requirements (Procurement)

• Greater interoperability of European

and US equipment

• More competition due to use and

design of new tools and processes

• In Short - it reduces the Through Life

Support Costs


Solutions supporting the Open System

Architecture - particularly ATML (IEEE Std 1671)

and 1641 (IEEE Std 1641) - offer significant

through-life cost savings.

Implementations that utilise 1641 and ATML are

varied in software architecture for both TPS &

ATS; several different vendors’ products are

included in the OSA-RTS.

A number of ATML and 1641 COTS tools are

available and systems have been built from

these COTS tools that bring ATML with 1641

compliance to existing ATS Architectures. These

capitalise on the investment made in these

existing run-time tools, configuration data and

training.

The OSA-RTS is a collection of open source

components that allow test standards to be

integrated into a ATS architectures.

Reduces Entry Costs

Open System Architecture Runtime System (OSA–RTS)

Overview


Open System Architecture RunTime System


The Open System Architecture Runtime System (OSA-RTS) provides a

common framework of shared ATS components that implement ATML

solutions for translating ATML’s 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 utilises LabWindows / CVI.

The OSA-RTS framework has been recently extended to also utilise the

LabVIEW environment providing runtime signal support through

Hardware Abstraction Layer (HAL) using Dynamic Dispatch to route

ATML operations to instrument VIs.
