Set Up a File Management System
As a model grows, managing referenced files and dependencies becomes more complicated. To reduce the complexity of managing large models, you can use projects. Projects in Simulink help to organize large model hierarchies by finding required files, managing and sharing files and settings, and interacting with source control.
Open the project BasicModelingProject
, which contains these files:
Subsystem file
ex_modeling_mechanical_system.slx
Model file
ex_modeling_variants.slx
Model file
ex_modeling_controller.slx
Model file
ex_modeling_operator_variant.slx
MATLAB script
ex_modeling_data_mechanical_system.m
MATLAB script
ex_modeling_data_controller.m
MATLAB script
ex_modeling_variant_choice.m
MATLAB function
ex_modeling_bus_objects.m
The MATLAB scripts and function are configured to Run at Startup.
The top model in the model hierarchy has a project shortcut. To open this model, on the Project Shortcuts tab, click Open Top Model.
Using this project, you can explore project capabilities, such as these capabilities:
Automate tasks
Create shortcuts for common actions
Analyze file dependencies
Analyze the impact of changing files
Compare model files
In the Views pane of the project, select Dependency Analyzer.
To run a dependency analysis on all the files in the project, click Analyze.
In the dependency graph that opens, click a dependency arrow to display its properties, including its dependency type, in the Properties pane. In this example, the MATLAB scripts and functions are run by model callbacks. Since these files run at startup in the project, the model callbacks are redundant and can be removed.
The dependency graph also shows the two-level model hierarchy, in which the top model depends on a referenced subsystem and referenced models.
