Semaphores, process priorities, and real-time tasks are examples of SDL extensions which integrate concepts of real-time operating systems into SDL. Providing tool support for such extensions, requires time and effort to manually adapt existing modeling and analysis tools. We present an approach based on language extension which reduces the effort to obtain a text editor for modeling and a runtime efficient next-event simulator for model analysis. The approach allows to prototype extensions, i.e., evaluate their design and suitability by test and simulation. We discuss an application of our approach to a subset of SDL. In addition, we take the concept of semaphores from SDL-RT and bring it to the SDL subset by defining it as an extension. The approach is implemented only in parts yet, thus we present work in progress. We discuss working prototypes for the text editor and the simulator.
