How to share outputs of a Button Checker model (slx file) to the other models(other slx files)

Button checker model 1(slx file) is built with 8 inputs (up, down , right, left, menu,back, home, power) and 8 outputs (up_k, down_k , right_k, left_k, menu_k,back_k, home_k, power_k). I get the button inputs from application.

Model 1 outputs has to be fed as inputs to Model2 (slx file)

I tried using Reference model approach. I made the Button checker model 1 as referene model in Model 2 slx file. I generated code. I got .c and .h files separately for Model 1 and 2. Integrated with application but my Model 2 is not able to get inputs from Model 1.

How do i do it. Please Help.

Hi @Febina,

To resolve this issue you can follow the below approches:

Approach 1: You can use a Subsystem Instead of a Model Reference:

• Convert the logic in Model 1 into a subsystem.
• Place this subsystem directly in Model 2.
• This way, Simulink generates integrated code, and the signals will be connected as expected in the generated code.

Approach 2: Explicitly Connect Models in Application Code:

• If you need to keep the Model Reference structure, you must manually connect the outputs of Model 1 to the inputs of Model 2 in your application code after code generation.
• This means, after calling the Model 1 step function and getting its outputs, you must assign those outputs as inputs to Model 2 before calling Model 2’s step function.

You can refer to the following links for more information on reusable Library Subsystem
