A new generation of tools based on SDL combines graphical easy-to-learn management of software with automatic generation of documentation and modifications. The code is optimized for embedded applications and for testing by adding the real-time elements needed for embedded systems. Unlike some other formal languages, SDL has been designed for general, real-time, event-driven applications.
