Inspect Model Hierarchies

To better understand a model hierarchy, you can use Simulink^®tools, functions, parameters, or preferences to:

Preview model contents
Visualize the model hierarchy
List referenced models andModelblocks
Display model version numbers

Content Preview

Content preview displays a representation of the contents of a referenced model on theModelblock. This preview helps you to understand at a glance the kind of processing performed by the referenced model without opening the referenced model. SeePreview Content of Model Components.

Model Dependency Viewer

The Model Dependency Viewer shows the structure of the model hierarchy and lets you open constituent models. TheModel Instancesview displaysModelblocks differently to indicate Normal, Accelerator, SIL, and PIL modes. SeeModel Dependency Viewer.

Thedepviewfunction opens the Model Dependency Viewer.

的模型引用列表

Thefind_mdlrefsfunction lists all models that are directly or indirectly referenced by a given model. This function also provides the paths to the relatedModelblocks.

Find Referenced Models in Model Hierarchy

Open Live Script

Find referenced models and Model blocks for all models referenced by the specified model.

load_system('sldemo_mdlref_basic'); [myModels,myModelBlks] = find_mdlrefs('sldemo_mdlref_basic')

myModels =2x1 cell array{'sldemo_mdlref_counter'} {'sldemo_mdlref_basic' }

myModelBlks =3x1 cell array{'sldemo_mdlref_basic/CounterA'} {'sldemo_mdlref_basic/CounterB'} {'sldemo_mdlref_basic/CounterC'}

Model Version Numbers

To display the version numbers of referenced models, in the parent model, on theDebugtab, clickInformation Overlays, then underBlocks, selectRef. Model Version. The version of eachModelblock instance appears on eachModelblock.

For information on model versions, seeManage Model Versions and Specify Model Properties.
