We describe the tool supported approach we developed for real-time systems modelling and schedulability analysis performed at the architecting phase of the software lifecycle. This approach integrates the “Pipelines of Processes in Object Oriented Architectures” (or PPOOA for short) method and tool for architecting real-time systems using UML notation, with the Cheddar tool for simulation and schedulability analysis of real-time software intensive systems. PPOOA and Cheddar were developed independently, so we have to adapt PPOOA, the method and tool we had developed, to be integrated with the Cheddar tool developed by the University of Brest. The goal of the paper is to show how this approach can be applied seamlessly to the architecting of small and medium real-time systems, identifying and solving concurrency problems at the architecture phase thus saving later testing and debugging efforts. An illustrative example of modelling and evaluation of an elevator control system is presented.
