痕迹StateflowElements in Generated Code

To verify the generated code for your Stateflow®elements, you can trace Stateflow elements in your model to the code generation report by using these types of navigation:

  • Code-to-model: Trace generated code from the code generation report back to the model by clicking hyperlinks in the comments or the hyperlinked line numbers, which highlights the corresponding model element in the Simulink Editor.

  • Model-to-code: Trace the model elements in the Simulink Editor to corresponding lines in generated code by right-clicking the model element and navigating to the generated code.

These examples illustrate how to trace different Stateflow elements.

内联的可追溯性StateflowElements

Inline traceability refers to the line-level traceability available in the code generation report. You can click the hyper-linked line numbers to trace single or multiple Stateflow elements at the same time.

  1. At the command prompt, typeold_sf_car.

  2. Select模拟>模型配置参数.

  3. In theCode Generation窗格，去Target selectionsection and enterert.tlcfor the system target file. ClickApply.

  4. Verify that you have selected these parameters on theCode Generation>Reportpane:

    • Create code generation report

    • Open report automatically

    • Code-to-model

    • Model-to-code

  5. 去Code Generation>Interfacepane. In theSoftware environmentsection, selectcontinuous time. ClickApply. Before generating code, you must perform this step because this model contains a block with a continuous sample time.

  6. PressCtrl+B.

    After the code generation process is complete, the code generation report appears.

  7. In the report, on the left navigation pane, click theold_sf_car.chyperlink.
