Summary:The Timing Definition Language (TDL) provides a component model and a tool chain as a solution for building time-safe components that can be developed independently and integrated in a distributed platform without changing the observable behavior and the code of existing components. TDL is based on the Logical Execution Time abstraction and supports the decomposition of hard real-time applications into modules that are executed logically in parallel. This paper presents the algorithms for automatic schedule generation of TDL communications over the hyperperiod. As modules may switch modes independently, we combine the messages from all modes in the schedule. Hence, we introduce several optimizations to save bandwidth and improve the schedule's feasibility.
