Refactor Models

Identify modeling clones and patterns to transform model

Use the Model Transformer and the Clone Detector to refactor a model to improve model componentization, readability and enable reuse.

Use the Model Transformer to:

Identify modeling patterns that qualify for transformation into Variant Source or Variant Subsystem blocks. Using Variant Subsystem and Variant Source blocks helps in the reusability of a model for different conditional expressions called variant choices. The active model is a combination of a fixed structure and variable components that you activate depending on the variant choice that you select.
Identify data store blocks that qualify for elimination. Eliminating data store blocks improves model readability by making data dependency explicit.
Identify n-D Lookup Table blocks that qualify for transformation into shared Prelookup blocks and multiple Interpolation blocks. This transformation improves the simulation efficiency.
Identify multiple Interpolation Using Prelookup blocks that qualify for transformation into a single Interpolation Using Prelookup block in a modeling pattern. This transformation improves the generated code efficiency.

Use the Clone Detector to:

Identify clones and create a model with the clones replaced by links to the subsystem blocks in a library. Replacing clones with links to library blocks enables component reuse.
Identify and replace clones in a model with the subsystem references.

Detect Clones Programmatically on Multiple Models Across Different Folders

Programmatically detect clones across multiple models located in different folders. For more information about the clone detection APIs, see Detect and Replace Subsystem Clones Programmatically.

Running Clone Detection Custom Script in a Project

Run a custom script for detecting clones on the set of Simulink® model files managed in a project. Creating a custom script would help to organize and automate the large modeling projects. For more information on setting up a custom task, see Run Custom Tasks with a Project.
