na_0005: Port block name visibility in Simulink® models
For some items it is not possible to define a single approach that is applicable to all organizations’ internal processes. However, it is important that within a given organization, a single consistent approach is followed. An organization applying the guidelines must enforce one of the following alternatives.
Apply one of the following practices:
The name of an Inport or Outport block is not hidden. (Format > Hide Name is not allowed.)
The name of an Inport or Outport block must be hidden. (Format > Hide Name is used.)
Exception: The names cannot be hidden inside library subsystem blocks.
Correct: Use of signal label
By Task > Modeling Standards for MAAB > Simulink > Check visibility of port block names
