13. SCOPE: Define structures in STIL for specification of the order of execution of test program components. Define structures in STIL such that test flows are specified in a structured manner to facilitate automated modification or maintenance. Define structures in STIL for specifying a common interface between the flow environment and test program components. Define structures in STIL for defining flow related variables and expression processing that is managed by the flow. Create in STIL examples of a test program components for the purpose of illustrating the key features of the interface. An example of a typical set of test program components shall be developed to model and demonstrate the flow methodology and common Flow-Test interface being proposed with this supplement. A set of test program components is to be developed by a separate working group (P1450.5). Define structures in STIL that provide for a hierarchy of flow and test component modules. Examples of the need for hierarchy in STIL is in support of sub-flows and binning.

Completion of this document contingent? Yes
The syntax of P1450.4 may need to use constructs now being finalized in P1450.1. It is anticipated that P1450.1 will be approved in advance of this project.

14. PURPOSE: STIL is the standard for the interchange of digital test data from the test generation environment (where a great deal of design information is used to generate device tests) to the test and manufacturing environment. The STIL standard initially addressed the essential digital test description information (i.e.. signals, timing, vectors and parameter specifications). Other aspects needed for testing devices were to follow in extension activities such as this standard to address test flow extensions to STIL. This extension will provide the constructs to describe the test program flow and sequencing data needed to compose a test program to run on an Automatic Test Equipment platform.

14a. Reason: This standard will facilitate the use of STIL on automatic test equipment.
