Create Architecture Views Interactively

The structural hierarchy of a system typically differs from the hierarchy of the functional requirements of a system. With architecture views in System Composer™, you can view a system based on different hierarchies.

Aviewshows 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:

操作视图demonstrate how a system will be used and should be integrated with requirements analysis.
Functional viewsfocus on what the system must do to operate.
Physical viewsshow how the system is constructed and configured.

A viewpoint represents a stakeholder perspective that specifies the contents of the view.

For example, you can author a system using requirements. A view allows you to better understand what components you need to satisfy your requirements while not necessarily focusing on the structure.

This example uses the architecture model for a keyless entry system to create component diagram views.

Acomponent diagramrepresents 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.

For more information on the keyless entry system architecture, seeModeling System Architecture of Keyless Entry System.

Create Filtered Views with Component Filters and Port Filters

In the MATLAB^®Command Window, enter this command.
```
scKeylessEntrySystem
```
The architecture model opens in System Composer.
Navigate toModeling>Architecture Viewsto open theArchitecture Views Gallery.
SelectNew>Viewto create a new view.
InView Propertieson the right pane, in theNamebox, enter a name for this view, for example,Software Component Review. Choose aColorand enter aDescription, if necessary.
In the bottom pane, selectView Configurations>Filter>Add Component Filterto add a form-based criterion to a component filter.
From theSelectlist, selectComponents. From theWherelist, selectStereotype. Selectisa. In the text box, from the list selectAutoProfile.SoftwareComponent.
SelectApply.
An architecture view is created using the query in theComponent Filterbox. The view is filtered to select all components with theAutoProfile.SoftwareComponentstereotype applied to them.
SelectAdd Component Filter. From theSelectlist, selectComponents. From theWherelist, selectName. Select~contains. In the text box, enter"Door Lock". Select theAuto Applycheck box so that future changes are applied without selectingApply.
An architecture view is created using the additional query in theComponent Filterbox. The view is filtered to select all components not named"Door Lock".
From theAdd Port Filterlist, select the optionHide Unconnected Ports.
An architecture view is created using the additional query in thePort Filterbox. The view is filtered to hide unconnected ports.
删除the port filter. Pause on the constraint and select thebutton.

Add Group By Criteria to Filtered Views

In the View Configurations pane, selectGrouping.
To choose a property enumeration for grouping, clickAdd Group By.
From the list, selectAutoProfile.BaseComponent.ReviewStatus.
ClickAdd Group Byagain.
From the list, selectAutoProfile.SoftwareComponent.ImplementationLanguage.
ClickApply.

Interactively Add and Remove Elements from Views

To add more components to the view, drag and drop components fromModel Components. Drag and drop theLighting Systemcomponent to theSoftware Component Reviewview. Alternatively, clickAddon the toolstrip. You can also pressCtrl+Ito add component instantiations to your view when they are selected.

Note

Interactively adding and removing elements from your view with an associated query is not supported. You will receive a warning message: Remove associated query? PressOKto proceed.

You can press删除to delete components from the view.
Observe that theLighting Systemcomponent has been added to the view.

This view is now considered a freeform view.

Add or Remove Requirements Links from Views

Navigate toRequirement>Requirements Manager. A Requirements Toolbox™ license is required. TheRequirement Linkstab appears at the bottom of theSoftware Component Reviewview.
Select theLighting Controllercomponent and observe the linked requirementAutomatically turn off headlights.
Select the requirementAutomatically turn off headlightsto open the Requirements Editor to view or modify requirement links.
In theArchitecture Views Gallery, navigate toRequirement>Open Requirements Editorif the Requirements Editor is not open already.
Select theShould unlock doorrequirement.
Return to theArchitecture Views Gallery. In theSoftware Component Reviewview, select theLighting Controllercomponent.
Navigate toRequirement>Link to selected requirement. The new requirementShould unlock dooris added.
To remove a requirement link, selectand confirm deletion.

Add Custom Clauses to Component Filters and Port Filters

SelectNew>Viewto create a new view.
InView Propertieson the right pane, in theNamebox, enter a name for this view, for example,Hardware Component View. Choose aColorand enter aDescription, if necessary.
In the bottom pane, underView Configurations>Filter, select from the listAdd Component Filter>Add Custom Component Filterto enter a constraint by which to filter. In the box, entercontains(Property('Name'),'Dashboard').
In the bottom pane, underView Configurations>Filter, select from the listAdd Port Filter>Add Custom Port Filterto enter a constraint by which to filter. In the box, entercontains(Property('Name'),'sound').
SelectApply.

The view is filtered using the constraints in the custom filters. For more information on structuring constraints, seesystemcomposer.query.Constraint.
