22、, IEEE Guide to the Use of the ATLAS Specication.)IEEE Std 716-1995, IEEE Standard Test Language for All SystemsCommon Abbreviated Test Languagefor All Systems (C/ATLAS), and ARINC Specication 626-3, Standard ATLAS Language for Modular Test,dene ATLAS, a standardized test language for expressing tes

23、t specications and procedures. This guidesupplements IEEE Std 716-1995 and ARINC Specication 626-3 and is part of the documentation set for thelanguage.The need for a guide to the use of ATLAS arose from the experience of users in the preparation of test proce-dures in the language. This experience

24、showed that differences of interpretation existed for technique andmethod, if not denition. The purpose of this guide is to provide guidance in the matter of technique andusage; it is seen as particularly important in promoting the use of the language envisaged by its originators.This document is no

25、t intended as an instruction manual for ATLAS nor as a substitute for some formal train-ing, but by its nature it should nd some applicability in the training environment.IEEE Std 771-1998 corresponds with IEEE Std 716-1995 and ARINC Specication 626-3. It is the intentionof the IEEE ATLAS Committee

26、that there shall be a continued correspondence between these standards andIEEE Std 771.The members of the ATLAS 771 Subcommittee during the preparation of this guide were as follows:Ashley M. B.

All rights reserved.1IEEE Guide to the Use of the ATLAS Specication1. OverviewThis guide is divided into clauses that introduce the history, use, and stru

45、cture of the Abbreviated Test Lan-guage for All Systems (ATLAS) language followed by general guidance on good usage practice. The mainclauses also contain information and language elements that apply to all test disciplines. The guide also contains annexes that provide more specic examples of ATLAS

46、usage as applied to particu-lar test disciplines. The information in each annex includes language elements and structures used in a par-ticular test discipline with some examples and descriptions of usage.1.1 ScopeThis guide has been written as an applications manual for engineers and others who wri

47、te test requirementsin ATLAS. The initial clauses are intended to provide managers with a brief introduction to the applicationof ATLAS. This guide is in no way intended to be a substitute for an instruction manual in the ATLAS lan-guage; rather it is intended to provide practical support to such a

48、manual.1.2 PurposeThe purpose of this guide is to provide principles of good practice in the use of ATLAS for writing testrequirements. This advice has been drawn from practical applications in many organizations and a numberof companies that generate test requirements in ATLAS. Since ATLAS must be

49、capable of communicating complex test requirements, the language has a largevocabulary and appropriate syntax. The guide concentrates on the proper use of the ATLAS syntax andsemantics for the generation of unambiguous test requirements. The guide assists in preparing test require-ments as well as in writing computer software that will efciently process ATLAS test requirements forautomatic implementation.1.3 Related documentsThe material in this guide is applicable to IEEE Std 716-1995 and ARINC Specication 626-3.
