In this paper we present new concepts to resolve ECU (Electronic Control Unit) failures in FlexRay networks. Our approach extends the FlexRay bus schedule by redundant slots with modifications in the communication and slot assignment. We introduce additional backup nodes to replace faulty nodes. To reduce the required memory resources of the backup nodes,(More)
—Many heterogeneous embedded systems, for example industrial automation and automotive applications, require hard-real time constraints to be exhaustively verified-which is a challenging task for the verification engineer. To cope with complexity, verification techniques working on different abstraction levels are best practice. SystemC is a versatile C++(More)
In this paper we investigate whether multi-objective evolution of digital hardware components has advantages over single-objective evolution in terms of convergence and robustness. To that end, we experimentally compare a standard genetic algorithm to several multi-objective optimizers on a set of test problems. The results show that, for more complex test(More)
—In this paper we present an approach to increase the fault tolerance in FlexRay networks by introducing backup nodes to replace defect ECUs (Electronic Control Units). In order to reduce the memory requirements of such backup nodes, we distribute redundant tasks over different nodes and propose the distributed coordinated migration of tasks of the defect(More)
This work proposes an advanced methodology based on an open source virtual prototyping framework for verification of complex Heterogeneous Embedded Systems (HES). It supports early rapid modelling of complex HES through smooth refinements, an open interface based on IP-XACT extensions for secure composition of HES components, and automatic testbench(More)
