What is an OSA-RTS

The Open Systems Architecture:

The OSA (Open Systems Architecture) comprises of :

Modular in Design, the OSA utilizes widely supported and consensus based Standards for the Key interfaces which have been subjected to successful validation and verification tests to ensure their openness.

The principles and characteristics of the OSA:

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.

ATML Core Components

The ATML demonstrations used core components to share information across a variety of traditional ATE platforms and In-Circuit testers.This walkthrough examines these core components to provide a detailed critique for other user of ATML, identifying the different methods and lessons learnt when creating ATML files for describing TPS files.The core components considered are

UUT Description

Describes the UUT Interface, test points, components and schematic interconnects associated with the UUT

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 Run-time

Implementing a 1641 runtime interface with calls to underlying test resources.

Signal Model Libraries

1641 Test Signal Framework IDL

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 adhere to those standards, to ensure interoperability.

ATML Components

Other ATML components and files used in these demonstartion but not neseccarly shared across all demonstrations include
