Lab 3: Debugging Imported C/C++-Code Using GDB Debugger - 2022.1 English

Model Composer provides the ability to debug C/C++ code that has been imported as a block using the xmcImportFunction command, while simulating the entire design in Simulink® .

The debug flow in Vitis Model Composer is as follows:

1. Specify the debug tool using the xmcImportFunctionSettings command.
2. Launch the debugging tool.
3. Add a breakpoint in the imported function.
4. Attach to the MATLAB® process.
5. Start Simulink simulation.
6. Debug the imported function during simulation.

This lab has two steps:

• Step 1 introduces you to the Optical Flow demo design example in GitHub. It shows you how to identify the custom library block, created using the xmcImportFunction feature.
• Step 2 shows you how to debug C/C++ code using the GDB tool.

For more details and information about how to create custom blocks, refer to the Vitis Model Composer User Guide (UG1483).
