For the real-time simulation of complex dynamic mechatronic systems, an increasing number of parallel CPUs are employed. The user is responsible for the specification and the partitioning of the system into separate sub models. Each sub model is assigned to its own node. Each sub model consists of several tasks, which are executed event-triggered or time-triggered. For the distributed real-time simulation, the tasks communicate with each other. In the near future, time-triggered bus architectures will play an important role because they provide deterministic and fault-tolerant communication. Time-triggered communication controllers are responsible for the execution of the communication in real-time systems connected via bus. The time-triggered communication approach affects the system modeling, the offline simulation, the code generation and the scheduling of communication tasks.
The main topic of the planned research project is to develop a seamless development process taking the following topics into consideration
- the specification of tasks,
- the specification of distributed inter task communication,
- the scheduling of the tasks,
- and their communication tuned to a planned communication schedule,
- OSEK operating system. For an integrated solution the specification of tasks, their communication and the code generation for the implementation on a prototyping CPU network and also on a target controller network
