Inspect Model Hierarchies

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

  • Preview model contents

  • Visualize the model hierarchy

  • List referenced models and Model blocks

  • Display model version numbers

Content Preview

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

Model Dependency Graph

The Dependency Analyzer displays the structure of the model hierarchy and lets you open the models in the model hierarchy. The Model Instances view displays Model blocks differently to indicate normal, accelerator, SIL, and PIL simulation modes.

Dependency Analyzer results for sldemo_mdlref_depgraph. A legend provides colors to identify the top model and simulation modes of the referenced models.

The depview function opens the model dependency graph.

For more information, see Analyze Model Dependencies.

List of Model References

The find_mdlrefs function lists the models that are directly or indirectly referenced by a given model. This function also provides the paths to the related Model blocks.

For example, find the referenced models and Model blocks in the MultiCounter model. This example opens the ModelReference project, which opens the MultiCounter model at startup.

openExample('simulink_features/ComponentBasedModelingUsingModelReferenceExample')
[myModels,myModelBlks] = find_mdlrefs("MultiCounter")
myModels =

  2×1 cell array

    {'LimitedCounter'}
    {'MultiCounter'  }


myModelBlks =

  3×1 cell array

    {'MultiCounter/CounterA'}
    {'MultiCounter/CounterB'}
    {'MultiCounter/CounterC'}

For more information, see find_mdlrefs.

Model Version Numbers

To display the version numbers of referenced models, in the parent model, on the Debug tab, click Information Overlays. Then, under Blocks, select Ref. Model Version. The version of each Model block instance appears on each Model block.

Three Model blocks display the same version number (Rev = 1.78).

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