IEEE 1641.1, Guide for the Use of the Standard for Signal and Test Definition
This is a companion document to the IEEE
Standard for Signal and Test Definition. The STD standard provides a rigorous
method of describing signals and tests. The Guide provides help and guidance to
new users by showing how the standard may be implemented. It provides
application information for those who write, develop, implement and support
test requirements, signal definitions, and signal responses using IEEE Std 1641.
The guide includes sections on the following:
• Historical Background
• The Hierarchy of the Signal Definitions
• Creating Signals using the STD Standard
• Documenting Signal Descriptions
• Implementing STD systems
• Basic Signal Components (BSCs)
• Test Signal Framework (TSF) models.
• The Test Procedure Language
• The Signal Modeling Language (SML)
• The relationship with ATML
The Guide includes examples of signals at all levels of the STD hierarchy. It explains how the Basic Signals interact to create more complex signals and how these more complex signals may be described in a single Test Signal Framework model. Examples using different carrier languages show how the BSC and TSF models are used in textual test requirements. The Guide also includes some examples of how the Signal Modeling Language is used to mathematically define the BSCs.
The TAD subcommittee has almost completed a project (P1641.1) to revise the STD User Guide. The 2006 version of the Guide is aligned with the 2004 version of the standard. Of course, most of the information in this version of the Guide is equally valid for the 2010 revision of the 1641 (STD) standard, but that does not mean that significant improvements are not being made. The revised guide includes a lot more information about implementing digital signals in 1641, and includes supporting information for some of the new capabilities introduced in the 2010 revision. The new version will have approximately 50% more pages and includes information from published application notes and implementation techniques.
The current draft is available for members of the working group in the Standards Drafts area.
