Generated Code Compilation

Specify build process that compiles generated source code and links object code

To produce executable code after source code generation, specify a build process that compiles the generated source code and links object code. You can use a CMake, toolchain, or template makefile approach for building code that you generate from Simulink^® models. MATLAB^® ships the CMake executable file. Each approach requires the installation of supported build tools. For information about customizing the build process for your development environment, see Code Compilation Customization.

To test numeric equivalence between your model and the generated code, you can use the SIL/PIL Manager.
