All
Rule
Sub ID a
The number of characters in the signal and bus name shall be less than or equal to configured limit. Default value is 63 characters.
Maximum signal name length
Maximum bus name length
Note
The MATLAB limit for the number of characters you can use in signal and bus names is 2048.
Signal name length is less than 63 characters.
The length of the hierarchical signal name (full path)
bus_all.bus_name_finla.bus_name2.abcdefghijklmn
is less
than or equal to 63 characters.
Rationale
Sub ID a:
Code generation may not be possible.
Verification
Model Advisor check: Check length of signal and bus names (Simulink Check)
