Change: Define general SW-Platform Stakeholder requirements and AoU

[aschemmel-tech]

Change Request Type

Feature Modification

Description of the Change Request

Several general safety topics on SW-Platform (Stakeholder) level are not covered to date.
One example is the error reaction any feature implementing safety mechanisms has to execute (to reach a "safe state") and how long this is allowed to take.
The definition of this may need to include additional AoU and Stakeholder requirements.
example AoU: "The platform expects an external watchdog ..." and Stkh-Req: "The platform triggers an external watchdog ..."

Estimates for realization
