The specific methods In ATS development based on IEEE 1641 STD

Traditionally, the only method to capture, describe and program test requirements in signal-oriented way is using ATLAS (Abbreviated Test Language for All System) language. The IEEE 1641 (Signal and Test Definition) STD Standard provides a new way to define test requirements independently of the language and test station platform. With this approach, instrument-independent test descriptions is no longer simply represented by a special formatted test language, but any languages which build on a framework for component libraries of signal descriptions. This paper studies specific method to implement ATS(Automatic Test System) based on IEEE 1641 STD, including the signal library creation, STD test statements mapping to the methods and attributes of BSCs(Basic Signal Component) and TSF(Test Signal Framework) signals, signal objects creation for particular TPL statements, signal-oriented test descriptions conversion to instrument setting etc.
