5.6 Sub problem Relationships:
The sub problem relationship of the component Automatic Cruise control System is
the same as problem diagram relationship in Phase 3.
5.7 Validation:
- All machine interfaces of the problem diagrams are captured.
- The signals in the sequence diagrams are the same as in the external interfaces.
- To each programmable component at least one problem diagram is associated.
- All problem diagrams are associated to the ACC.
- All domains in the problem diagrams being part of the machine are associated to
a component.
- Only one machine domain in the context diagram exists. Its structure is given by
the architecture.
- The purpose of each component is consistent to the associated requirements.
