Model Configuration Parameters: Code Generation

The Code Generation category includes parameters for defining the code generation process including target selection. It also includes parameters for inserting comments and pragmas into the generated code for data and functions. These parameters require a Simulink® Coder™ license. Additional parameters available with an ERT-based target require an Embedded Coder® license. Generating CUDA® C++ code for NVIDIA® GPUs requires a GPU Coder™ license.

These configuration parameters appear in the Configuration Parameters > Code Generation general category.


System target file

Specify which target file configuration will be used.


Browse file configuration options.

Shared coder dictionary (Embedded Coder)

Shared coder dictionary that contains code interface configuration.


Specify C or C++ code generation.

Specify the language standard for your execution environment.

Generate GPU code

Use GPU Coder for CUDA code generation.

This parameter requires a GPU Coder license.
