Is there a way to use S-Function to create a message receiver block

I was trying to create a customized block with a message receiving input port. The SimStruct Functions seem not be able to achieve this feature. I know it's available to mask a built-in Receive block, but it would be better to use S-Function to gain more customizability.

Thanks.

Hi Xunkai,

I understand that you want to create a customized block in Simulink with a message receiving input port. You can use an S-Function to achieve this level of customization. S-Functions allow you to create custom blocks in Simulink using MATLAB or C/C++ code.

To create an S-Function with a message receiving input port, follow these general steps:

1. Create a new MATLAB or C/C++ file
2. Define the parameters and options for your S-Function, including the input and output ports, block dialog parameters, and any other required configuration settings.
3. Implement the necessary S-Function methods to define the behavior of your custom block.
4. Compile the MATLAB or C/C++ code into an S-Function in MATLAB.
5. Once the S-Function is built, you can use it as a custom block in your Simulink models. Add the S-Function block to your Simulink diagram and configure its parameters as needed.

For detailed explanation, please follow the documentation.
