Heterogeneous Prototyping for Distributed Real-Time Systems

Abstract The purpose of this paper is to present some extensions to the IDERS environment, in order to deal with the development of distributed real-time systems. The IDERS method and tools are intended to support the user in the development of embedded monoprocessor real-time systems. This environment is based on a risk oriented process model. The development of the systems relies on a set of heterogeneous and incremental prototypes that can be animated in order to assess the system behaviour. In this paper, an extension of this toolset for supporting the development of distributed real-time systems is proposed. This extension includes the modeling of the communication media, in order to have information on the whole system behaviour. Special emphasis will be made for including mechanisms for assessing the system timing requirements.
