jc_0656: Usage of Conditional Control blocks
Sub ID Recommendations

MATLAB Versions

Rule
Sub ID a
To make all actions in the conditions explicit, these block parameters shall be set as follows :
For If blocks, select Show else condition
For Switch Case blocks, select Show default case
Not Applicable
Using default behavior in the Switch Case block.
Not using default behavior in the Switch Case block.
Rationale
Sub ID a:
Determining whether there is pointless processing or if something is missing from the design (such as a missing description) is easier when the processing of exceptions (
else,default) is explicitly set in the model.
Verification
Model Advisor check: Check default/else case in Switch Case blocks and If blocks (Simulink Check)
