jm_0010: Port block names in Simulink® models
For some items, though you may not be able to define a single approach for internal processes of all organizations, within a given organization, try to follow a single, consistent approach. An organization applying the guidelines must enforce one of the following options:
Names of Inport and Outport blocks must match corresponding signal or bus names.
When any combination of an Inport block, an Outport block, and any other block have the same block name, use a suffix or prefix on the Inport and Outport blocks.
One common suffix / prefix is
Inport blocks and
_out for Outport blocks.
You may use any suffix or prefix on the ports, however, the prefix that you select must be consistent.
Library blocks and reusable subsystems that encapsulate generic functionality.
When names of Inport and Outport
blocks are hidden, apply a consistent naming practice for the blocks. Suggested
practices include leaving the default names (for example,
giving them the same name as the associated signal, or giving them
a shortened or mangled version of the name of the associated signal.
