To set Simulink Profiler to generate a report with the rows in the table showing the processing time taken by each task's subsystem block, follow these steps:
For the subsystem block corresponding to each of the tasks in the model,
1. Right-click on the subsystem block and click on "Block Parameters (Subsystem)" near the bottom of the menu.
2. In the "Main" tab, enable the "Treat as atomic unit" option.
3. In the "Code Generation" tab, in the drop-down menu for "Function Packaging:", select the "Reusable function" option.
4. Click the "OK" button.
In the Simulink model, navigate to the following setting:
Configuration Parameters > "Verification" tab > Measure function execution times
Set to "Coarse (referenced models and subsystems only)"
Click on the OK button.
Now follow one of the procedures to run the model with the profiler on, such as:
>> modelName = 'simulink_model_filename_noExt';
>> load_system(modelName)
>> set_param(modelName,'Profile','on')
>> sim(modelName);
The above solution was verified in MATLAB R2019b.
