Model-based development has become state of the art in software engineering. Unfortunately, the used code generators often focus on the pure application functionality. Features like automatic generation of fault-tolerance mechanisms are not covered. One main reason is the inadequacy of the used models. An adequate model must have amongst others explicit execution semantics and must be suited to support replica determinism and automatic state synchronization. These requirements are fulfilled when using the concept of logical execution time, a time-triggered approach. This approach hides the implementation details like the physical execution from the user, In contrast to other time-triggered paradigms. Within this paper, we present a solution to exploit this concept to realize major fault-tolerance mechanisms in a generic way1.
