There are some SDL symbols. SDL diagrams are a particular kind of diagram that employ the graphical components of Specification and Description Language (SDL) to design object-oriented diagrams, model state machines in the communication, telecommunications, aviation, automotive, and medical industries, and create specifications and descriptions of behavior, data, and inheritance for interactive real-time systems, reactive, and distributed systems. EdrawMind lets you draw a SDL digram with its symbols in a few simple steps.
