Can you please provide the complete model being used here?
You can refer to the following points to try to identify the issue:
- Please note that subsystem model test harnesses do not support SIL verification, as stated in the following documentation: https://www.mathworks.com/help/releases/R2023b/sltest/ug/select-test-harness-properties-for-your-task.html#bun8a9w
- Kindly refer to the following documentation that specifes the workflow to perform SIL unit tests on atomic subsystems: https://www.mathworks.com/help/releases/R2023b/ecoder/ug/unit-test-subsystem-code-with-silpil-manager.html
- Target-specific (NXP, in this case) custom-code in the model that is not portable for execution on the development computer can lead to build errors. You can refer to the following documentation for SIL simulations to understand more about the limitations for SIL: https://www.mathworks.com/help/releases/R2023b/ecoder/ug/sil-and-pil-simulation-limitations.html#mw_0756ee83-0e45-469c-964a-c60354c06971
- The hardware implementation settings should be configured to allow for SIL compilation on the development computer, as specified in the following documentation: https://www.mathworks.com/help/releases/R2023b/ecoder/ug/software-and-processor-in-the-loop-sil-and-pil-simulation.html#d126e253047
