How can I generate an empty file and function using Real-Time Workshop which can be populated later by user’s custom code?

Using the code generation I want to generate an empty file with empty function to be populated by me later.

RTW optimizes the empty subsystem. I do not want that to happen.

User can achieve this using atomic subsystem. Please see an example model attached.

Please follow the steps below:

1. Use atomic subsystem block on your model. Keep it empty as shown in the model attached.

See doc for Atomic subsystems,

https://www.mathworks.com/help/simulink/slref/subsystem.html

2. Right click the block and select ‘Subsystem Parameters’.

3. Then do following settings,

-- For ‘Real Time Workshop system code’ select ‘Reusable function’. (Default is Auto)

-- For ‘Real Time Workshop function name option’ select ‘User Specified’.

-- Enter the name for the function in the text box that appears.

-- For ‘Real Time Workshop file name option’ select ‘User Specified’.

-- Enter the name for the file to be generated for the atomic subsystem.

4. Generate the code.
