Construct Query to Select All Interface Elements
Import the package that contains all of the System Composer™ queries.
Open the Simulink® project file for the keyless entry system.
Load the architecture model.
model = systemcomposer.loadModel("KeylessEntryArchitecture");
Create a query for all the interface elements with
c in the
Name and run the query.
constraint = HasPort(HasInterface(HasInterfaceElement(contains(Property("Name"),"c")))); elements = find(model,constraint,Recurse=true,IncludeReferenceModels=true)

A view shows a customizable subset of elements in a model. Views can be filtered based on stereotypes or names of components, ports, and interfaces, along with the name, type, or units of an interface element. Create views by adding elements manually. Views create a simplified way to work with complex architectures by focusing on certain parts of the architectural design.
You can use different types of views to represent the system. Switch between a component diagram, component hierarchy, or architecture hierarchy. For software architectures, you can switch to a class diagram view.
A viewpoint represents a stakeholder perspective that specifies the contents of the view.

An element group is a grouping of components in a view.
Use element groups to programmatically populate a view.
A query is a specification that describes certain constraints or criteria to be satisfied by model elements.
Use queries to search elements with constraint criteria and to filter views.
|Find Elements in Model Using Queries|
A component diagram represents a view with components, ports, and connectors based on how the model is structured.
Component diagrams allow you to programmatically or manually add and remove components from the view.
|Inspect Components in Custom Architecture Views|
You can visualize a hierarchy diagram as a view with components, ports, reference types, component stereotypes, and stereotype properties.
There are two types of hierarchy diagrams:
