Modeling and simulation of embedded real-time multicore systems

In order to handle the continuously growing functionality in embedded systems, model-based approaches have been established in the development process over the last years. For singlecore architectures, model-based development has increased efficiency of development and software quality. Current trends show that embedded systems will change to multicore architectures within this decade. In this paper, we argue for a work-efficient migration from single- to multicore architectures through a model-based development process. Concerning the modeling of software and hardware components, we propose relevant properties of an architecture description language. Regarding the design phase, we show how simulation technology can be used for schedulability examination supporting engineers for system design decisions. Afterwards we extend the simulation approach by Monte-Carlo parametrization. Finally we evaluate the enhanced approach in a case study, located in the automotive powertrain domain
