Check Model and Configuration for Code Generation

You can use the Model Advisor checks to assess model readiness to generate code. To check and configure your model for code generation application objectives such as traceability or debugging, use the Code Generation Advisor.

To check model rtwdemo_throttlecntrl for code efficiency, use the Model Advisor.

  1. Open rtwdemo_throttlecntrl. Save a copy as throttlecntrl in a writable location on your MATLAB® path.

  2. On the Modeling tab, click Model Advisor. A dialog box opens showing the model system hierarchy.

  3. Click throttlecntrl and then click OK. The Model Advisor window opens.

  4. Expand By Task > Code Generation Efficiency. To check your model for code generation efficiency, use the checks in the folder. By default, checks that do not trigger an Update Diagram are selected. The checks available for code generation efficiency depend on whether you have a Simulink Coder or Embedded Coder license.

  5. In the left pane, select the remaining checks, and then select Code Generation Efficiency.

  6. In the right pane, select Show report after run and click Run Selected Checks. The report shows a Run Summary that flags check warnings.

  7. Review the report. The warnings highlight issues that impact code efficiency. For more information about the report, see View Model Advisor Check Reports.

Check Model During Code Generation

To review a model as part of the code generation process, use the Code Generation Advisor .

  1. To select and prioritize your code generation objectives, on the Configuration Parameters > Code Generation pane, click Set Objectives.

  2. On the Configuration Parameters > Code Generation > General pane, select one of the following from Check model before generating code:

    • On (proceed with warnings)

    • On (stop for warnings)

  3. If you want to only generate code, select Generate code only. Otherwise clear the check box to build an executable.

  4. Apply your changes. Press Ctrl+B to generate code or build the model.

    If the Code Generation Advisor issues failures or warnings, and you specified:

    • On (proceed with warnings) — The Code Generation Advisor window opens while the build process proceeds. After the build process is complete, you can review the results.

    • On (stop for warnings) — The build process halts and displays the Diagnostic Viewer. To continue, you must review and resolve the Code Generation Advisor results or clear the Check model before generating code parameter.

  5. In the Code Generation Advisor window, review the results by selecting a check from the left pane. The results for that check display in the right pane.

  6. After reviewing the check results, you can choose to fix warnings and failures as described in Fix a Model Advisor Check Warning or Failure.


    When you specify an efficiency or Safety precaution objective, the Code Generation Advisor includes additional checks. When you make changes to one of these additional checks, previous check results can potentially become invalid and need to be rerun.
