Signal and test definition - an IEEE standard

This paper presents a summary of the new signal and test definition standard (STD) to be published by the IEEE. It is an update to the paper 'signal definition and test description - an IEEE standard' presented at Autotestcon 2002, reflecting the latest developments in the STD standard. STD represents a radical departure from previous approaches to test description, in that it no longer simply represents a test language, as typified by ATLAS standards such as IEEE Std. 716-1995. Instead it provides a framework for component libraries of signal descriptions, which can be readily deployed in today's automatic test systems (ATS) with other standards such as the IVI signal interface from the IVI foundation. The other major benefit of this standard is the ease with which users can extend the signal types to describe emerging technologies and their associated signal requirements.
