SDL
Specification and Design Language.
Defined by the ITU-T (recommendation Z100) to provide a tool for unambiguous
specification and description of the behaviour of telecommunications systems.
The area of application also includes process control and real-time
applications. SDL provides a Graphic Representation (SDL/GR) and a textual
Phrase Representation (SDL/PR), which are equivalent representations of the same
semantics. A system is specified as a set of interconnected abstract machines
which are extensions of the Finite State Machine (FSM).
