Task: Analyze Timing Quality of Controller
Relationships
Main Description

During this task, the overall timing behavior of the ECU executing the implemented control applications is evaluated. Of course, all timing constraints of the system must be satisfied. However, for the trade-off analysis between control quality and timing quality performed during the task Verify and Assess Trade-off, we want to apply more sophisticated timing metrics expressing the extensibility of the overall system. A simple possible metric for extensibility is the load situation on the ECU. More expressive metrics are based on sensitivity analysis (see for instance Arne Hamann, Razvan Racu, Rolf Ernst: Multi-dimensional Robustness Optimization in Heterogeneous Distributed Embedded Systems. IEEE Real-Time and Embedded Technology and Applications Symposium 2007).
