"5.6 Digital Delivery of Electrical/Electronic Item Product Data.

5.6.4.2 Digital Electronic Product Item Functional Design Description Data Package. 
This deliverable describes the abstract or functional performance of the digital
electronic product item without reference to detailed physical implementation.  It
replaces while expanding upon the Logic Diagram Drawing referenced in DOD-STD-100. 
Its purpose is to provide a comprehensive adequate description of digital electronic
products (at the integrated circuit or digital printed circuit board assembly level)
for: design review by the program office; procurement of functionally equivalent
parts; test program development; and a variety of other logistics activities.  Higher
levels of digital system integration (box or system) are generally described by their
schematic diagram or network listing of interconnection between parts or assemblies
(communicated by the common data elements document type), accompanied by functional
design product description documents for the assemblies or parts, although  an
entirely digital box may be preliminarily described by a behavioral description. 
This data package consists of the following data elements:

	1.	Common product description elements

	2.	Behavioral description of digital electronics to consist of: Algorithmic
          Description; Quantitative Performance (Behavioral); Operating Range;
          Behavioral Simulation Data, Including Models.

	3.	Logical description of digital electronics to consist of: Logical
          Structural Description; Logic Simulation Data, Including Models

	4.	Timing Description (including rise, fall, delay and propagation times)

	5.	Test Vectors"

"5.6.5.2 Digital Electronic Product Item Functional Description Data Package.  The
digital electronic product item functional design data package serves to communicate
a wider range of product description information than the common descriptive document
type and would normally  be initially delivered in conjunction with the Preliminary
Design Review to be updated at Critical Design Review.  Another delivery (to take
place at the end of full scale development) would support development of test
programs and other logistics activities.  An additional delivery (to take place
before full rate production) is required for documentation of all digital electronic
components or assemblies for which reprocurement or resupply might reasonably be
expected.  Specifically, this deliverable should apply to: Commercially Available
Integrated Circuits (behavior, timing, and test vectors), Application Specific
Integrated Circuits (behavior, structure, timing, and test vectors), and all
reprocureable digital printed wiring assemblies (behavior, and external timing).

Items 2 through 5 shall be delivered as independent descriptions; i.e. the timing
description shall not be embedded with either the logical or behavioral description. 
The content of item 1 may be embedded within other items.  Unless otherwise specified
by the program office, this document type shall be delivered in VHDL format."
