How to Create a 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 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 devided into blocks, each of them can be describes 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 manageable part thatcan be followed separately. ConceptDraw Specification and Description Language solution contains the library, with a 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. Read more

SDL Flowchart Symbols

Drawing the diagrams we try to find in help the powerful software and now we have the ConceptDraw PRO. 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 PRO 2 libraries - SDL Connectors and SDL Diagrams that contain 70 predesigned SDL flowchart symbols. Read more

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.

"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]
