Control of model data and elements in generated code

The code that you generate from a model contains functions and variables that correspond to the systems, signals, and block parameters in the model diagram. To tune parameters and monitor signals and states during code execution, and to ease the integration of the generated code with your own code, you can control the declarations and definitions of functions and variables. You can specify:

  • Identifiers

  • Parameter tunability

  • Placement in generated or imported files

  • Data types

The generated code contains multiple entry-point functions that allow you to:

  • Create modular code that contains reusable reentrant functions.

  • Schedule model execution and data initialization on your target hardware.

Access Signal, State, and Parameter Data During Execution

As you iteratively develop a model, capture output signal and state data that model execution generates. Tune parameter values during execution to observe the effect on the outputs.

Function Reuse in Generated Code

This example shows how to configure an atomic subsystem for code generation. To specify that a subsystem's code executes as an atomic unit, select theTreat asatomic unitparameter on the block parameters dialog box. This parameter enables theFunction Packagingparameter of theCode Generationtab. TheFunction Packagingparameter has these four settings:Inline: Inline the subsystem code

File Packaging for Models (Code and Data)

File Packaging for Models (Code and Data)

This example shows how referenced models provide system interface encapsulation and incremental code generation. You can reference one model from another model (one or more times), and all aspects of the referenced model are fixed: input/output signal types, parameter types, and sample times. Therefore, you can modularize your design and perform incremental code generation with Simulink Coder.
