How to Create an SDL Diagram

Create an SDL Diagram
Specification and Description Language (SDL) is intended to describe systems that switched state often and rapidly. An SDL diagram is a view of a system, that can depict a single process or complex relationships between a number of elements. The SDL diagram supports a nested hierarchy. A system is divided into blocks, each of them can be described as a process until finally, one can see the initial procedures that make up each process. The advantage of this method is that a system can be viewed in a manageable part that can be followed separately. ConceptDraw Specification and Description Language solution contains the library, with an SDL notation in a vector stencil graphics. The SDL solution also provides a set of samples, to show the level of hierarchical detail that is possible.

SDL Flowchart Symbols

Drawing the diagrams we try to find in help the powerful software and now we have the ConceptDraw DIAGRAM. The ability easily create the SDL diagrams is made possible thanks to unique Specification and Description Language (SDL) Solution from the Industrial Engineering Area of ConceptDraw Solution Park. This solution extends ConceptDraw DIAGRAM 2 libraries - SDL Connectors and SDL Diagrams that contain 70 predesigned SDL flowchart symbols.

SDL Diagram

Specification and Description Language (SDL) is used for creating the object-oriented diagrams, visualizing the processes of the state machines for the systems of communication, telecommunication, automotive, aviation and medical industries. SDL is a specification language for creating specifications, descriptions of the behavior, data, and inheritance for real-time systems.
This sample shows the SDL Diagram of the process game.

System Design

ConceptDraw DIAGRAM system design software is a product of CS Odessa that was developed especially for making it much simpler to create all the needed diagrams, charts, flowcharts, schemes and other drawings when there is such a need in it. Having the Specification and Description Language (SDL) solution installed from the ConceptDraw STORE application may be another bonus to any ConceptDraw DIAGRAM diagramming and drawing software’s user as it offers both stencil libraries with the design elements and the pre-made examples of the diagrams, such as the SDL ones.

"Behavior.
Each process agent is a state machine that contributes to the action carried out by the system. A message stimulus coming from the environment or from another agent to an agent is called a signal. Signals received by a process agent are first placed in a queue (the input port). When the state machine is waiting in a state, if the first signal in the input port is enabled for that state it starts a transition leading to another state. Transitions can output signals to other agents or to the environment. A process agent is allowed to contain procedure types so that the same actions can be invoked from different places. It is also allowed to call a remote procedure type to invoke a procedure in another agent (or even another system) and wait for a response." [Specification and Description Language. Wikipedia]
