Hi Jack
Kindly refer to the following points to gain understanding on performing back-to-back testing between the Simulink submodel and the custom C code in Simulink Test Manager.
- Import your custom C code into Simulink using a C MEX S-Function block.
- Open Simulink Test Manager and create a new test using "Create Test for Model Component".
- Select the option "Perform back-to-back testing".
- Set Simulation 1 to Normal mode to run the Simulink submodel.
- Set Simulation 2 to Software-in-the-Loop (SIL) mode to run your custom C code.
- Make sure your C code setup supports SIL execution (compiled correctly and compatible with Simulink).
- Run the test to automatically compare outputs from both implementations.
For more information regarding Simulink Test Manager, kindly refer the following documentation - https://www.mathworks.com/help/sltest/ref/simulinktestmanager.html
I hope this helps
