hisl_0079: Connections to root input/output ports

ID: Titlehisl_0079: Connections to root input/output ports
DescriptionTo improve traceability, adhere to the internal connection constraints on the root-level Inport and Outport blocks of the current model.
NoteWhen internal connections to the root-level port blocks of a model are invalid, the software silently inserts hidden blocks to satisfy the constraints wherever possible. The hidden blocks can result in generated code without traceable requirements.
RationaleImprove robustness of design.
Model Advisor ChecksCheck for invalid root input and output port connections (Simulink Check)
