both ECUs and the bus and additionally have knowledge about the desired allocation of logical
components to technical components. In Figure 5.19, the component ECU1 is modeled containing
different types of technical components. First, there are two tasks named ECU1Task1
and ECU1Task2. To determine the necessary number of tasks, knowledge of the intended allocation
is required. In this example, we decided to allocate two logical components on ECU1
using two tasks.
A further component of ECU1 is a scheduler component ECU1Sched that schedules a number
of scheduler slots using a certain strategy which is here Fixed Priority Scheduling (FPS).
Each slot is linked to a task. For the communication with other ECUs via the CAN bus an
interface is needed that is modeled by the ECU1BusIf component. This interface component
has links to each task and to ports of the parent component ECU1 leading to the bus component.
