HSSP specification work is divided into two foundational components : functional specifications ( manifested as Service Functional Models ) and technical specifications ( resulting in technology adoptions ).
22.
In 1975, the IEEE published ANSI / IEEE Standard 488-1975, IEEE Standard Digital Interface for Programmable Instrumentation, which contained the electrical, mechanical, and functional specifications of an interfacing system.
23.
This project involves the creation of digital record of artefacts demonstrating design in plastics and the functional specification to support research into design in plastics and its cultural impact.
24.
Such " Functional Specification Theories " ( FSTs ) ( Levin, ?3.4 ), as they are called, were most notably developed by David Lewis and David Malet Armstrong.
25.
Ethnography enables the translation of qualitative findings into design principles for the purpose of obtaining functional specifications, bridging the disciplines of qualitative research with that of engineering and software development.
26.
A good part of the first year was taken up by meetings and planning, the result of which was an extensive and detailed functional specification, internally termed the " Red Book ".
27.
Design verification is often the most time-consuming portion of the design process, due to the disconnect between a device's functional specification, the designer's interpretation of the specification, and the imprecision of the HDL language.
28.
On more complex systems multiple levels of functional specifications will typically nest to each other, e . g . on the system level, on the module level and on the level of technical details.
29.
The project was started in 1999 . Besides being used to test regular programs, QuickCheck is also useful for building up a functional specification, for documenting what functions should be doing, and for testing compiler implementations.
30.
The train-control component of ERTMS, termed European Train Control System ( ETCS ), is a functional specification that incorporates some of the former national standards and allows them to be fully interoperable with a few modifications.
