NA-MAAB — b
JMAAB — a, b
The number of inputs/outputs for a Variant Subsystem block and its child subsystem or model reference shall be the same.
The number of inputs to the child subsystem is different.
The number of inputs/outputs for a Variant Model block shall be the same as its referenced model.
The number of inputs to the referenced model is different than the inputs to the Variant Model block.
Sub IDs a, b:
Unconnected signals can be unintentionally overlooked when the number of inputs/outputs is different.
