Model Configuration

Configure models for simulation and code generation

The model configuration parameters for code generation define how the code generator produces code and builds an executable from your model. The Model Advisor checks that your model meets standards and guidelines and is ready to generate code. The Code Generation Advisor reviews your model based on objectives that you specify.
