Simulink C-Code Generationed logic?

Question

simple question here. I would like to examine the generated c code after it has been generated from Simulink. The problem is, I cannot find any of the logic code, or variables from the model. I've looked through the internet for a solution, but there's nothing that really points me in the right direction. Can anybody elaborate on what kind of structure is used when creating auto-generated c code from Simulink? I'd like to look at how the actual logic was created. I made a simple comparison model with three inputs and an or block, and a to-workspace block. Any help is greatly appreciated.

Answer 1

When Simulink generates C code from a model, it typically follows a structured approach. The generated code structure depends on factors such as the complexity of the model, the types of blocks used, and the solver settings. However, I can provide a general overview of the structure you might encounter based on your description of a simple comparison model with three inputs, an OR block, and a To Workspace block.

1. Input Handling:
2. The generated code would likely include sections for handling the three inputs from your model. This could involve declaring variables to store the input values and incorporating code to fetch or receive these input values.
3. Logic Implementation:
4. The code would include the logic implemented by the OR block in your Simulink model. This could involve conditional statements, bitwise operations, or any other relevant logic to perform the OR operation on the inputs.
5. To Workspace Block:
6. If you have a To Workspace block in your Simulink model, the generated code would include instructions to store the relevant data in memory or a designated workspace. This could involve array assignments or function calls to transfer the data.
7. Header Files and Function Definitions:
8. The generated code would likely include header files that declare necessary functions, structures, and data types. Additionally, there would be function definitions that encapsulate the logic of your Simulink model.
9. Solver and Integration Handling:
10. Depending on your model's solver settings, the generated code might include sections related to solver methods and integration steps. This ensures that the simulation results are accurately translated into C code.
11. Initialization and Cleanup:
12. The code might include sections for initialization and cleanup routines, ensuring that the generated code can be seamlessly integrated into a larger software system.

To get a detailed view of how the actual logic was created, you should inspect the generated C code directly. You can typically find the generated code in the specified code generation folder within your Simulink project. Look for files with extensions like .c, .h, or similar, and review the content within these files to understand the specifics of the code structure and logic implementation.
