Standard Test Interface Language (STIL) file is an IEEE standard (1450) that describes an interface between digital test generation tools and test equipment. A test description language is defined that: (a) facilitates the transfer of digital test vector data from CAE to ATE environments; (b) specifies pattern, format, and timing information sufficient to define the application of digital test vectors to a DUT; and (c) supports the volume of test vector data generated from structured tests
The Importing STIL File dialog is similar to the importing WGL file dialog with one exception that the user can select which pattern in the STIL file to import (STILL file format may contain number of patterns).
