ID: Titlehisl_0078: Usage of identical modeling patterns
DescriptionTo reduce the complexity of generated code and increase its robustness, account for identical and similar modeling patterns in the model.
NoteClones are either identical or similar modeling patterns in the model. Clones can increase the model complexity and complexity of generated code. They also hamper readability and maintainability. Clone Detector (Simulink Check) app can be used to detect clone patterns. Library blocks of the clones can be created and replaced with links to those library blocks or from an existing library.
Rationale

  • Improve model compartmentalization.

  • Improve model and code readability.

  • Improve model and code reusability.
