Create Architecture Views Interactively - MATLAB & Simulink (original) (raw)

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

For a roadmap of the views topics, see Create Custom Views Using Architecture Views Gallery.

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.

Create Views with Component Filters and Port Filters

Create views with component filters to choose a collection of components to display in your view. Use port filters to further simplify your view and show only relevant ports and connections.

Create View in Architecture Views Gallery

1. In the MATLAB® Command Window, enter this command.
   The architecture model opens in System Composer.
2. Navigate to > to open the Architecture Views Gallery.
   
3. Select > to create a new view.
4. In View Properties on the right pane, in theName text box, enter a name for this view, for example, Software Component Review. Choose a color and enter a description, if necessary.
   

Add Component Filters and Group Ports

1. In the View Configurations pane, on theFilter tab, click Add Component Filter to add new form-based criterion to a component filter.
2. From the Select list, selectComponents. From theWhere list, selectStereotype. Select . In the text box, selectAutoProfile.SoftwareComponent.
   
3. Click .
   System Composer creates a view using the query in the Component Filter box. The view filter selects all components with theAutoProfile.SoftwareComponent stereotype applied.
   
4. You can select Group Ports in the Architecture Views Gallery toolstrip to simplify complex networks of connections and ports.
   
   Each grouped set of ports connects to a common set of components. In this example, the view does not group port AtoB because the port group containing components A andB belongs to a different component set from the port group containing components A, B, andC.
   
   
   To revert to the original component diagram view, clear Group Ports. For more information, see Group Ports in Component Diagram Views.
5. Select Add Component Filter. From theSelect list, selectComponents. From theWhere list, select Name. Select . In the text box, enter"Door Lock". Select the Auto Apply check box to apply future changes without selectingApply.
   
6. An architecture view is created using the additional query in theComponent Filter box. The view is filtered to select all components not named "Door Lock".
   

Add Port Filters

1. From the Add Port Filter list, select the optionHide Unconnected Ports.
   
2. An architecture view is created using the additional query in thePort Filter box. The view is filtered to hide unconnected ports.
   
3. Delete the port filter. Pause on the constraint and select theDelete button.

Add Group By Criteria to Views

1. In the View Configurations pane, selectGrouping.
2. To choose a property enumeration for grouping, click Add Group By.
3. From the list, selectAutoProfile.BaseComponent.ReviewStatus.
4. Click Add Group By again.
5. From the list, selectAutoProfile.SoftwareComponent.ImplementationLanguage.
6. Click Apply.
   

Edit Views Interactively

With the Architecture Views Gallery tool, you can edit and rearrange your view layout interactively.

• Click and drag components anywhere inside or outside the views canvas. Resize components inside and outside the views canvas. The views canvas expands to accommodate the moves.
• Move and resize a parent component with its children. Rearrange child components inside a parent component. After moving a child component, the parent component expands to accommodate the change.
• When a moved or resized component partially overlaps another component, the system is highlighted to indicate an incorrect final state.
• Click and drag around a region to select multiple components and manipulate them together.
• Double-click a component on the Model Components browser to add the component to the diagram. Right-click a component on theModel Components browser for additional options.
• Undo or redo interactive edits on the views canvas.

You can also use the Interface Editor tool from within the Architecture Views Gallery to add, edit, and delete interface definitions and interface data dictionaries. For more information, see Use Interface Editor in Views.

Follow these steps to add or delete elements from a view using the Model Components browser.

1. To add more components to the view, drag and drop components fromModel Components. Drag and drop the Lighting System component to the Software Component Review view. Alternatively, click Add on the toolstrip. You can also press Ctrl+I to add component instantiations to your view when you select them.
   
   To delete components from the view, select your component. On theArchitecture Views Gallery toolstrip, from the menu, clickRemove.
2. Observe that the Lighting System component has been added to the view.
   
   You can add or remove components manually in views without deleting your initial filter because the filter is augmented to reflect your manual edits to the view.
   To remove a component from your view, use the keyboard shortcutBackspace on Windows or Delete on a Mac. To delete a component from the model when using the component diagram view canvas, use the keyboard shortcut CTRL+Backspace on Windows orCommand+Delete on a Mac.

Add or Remove Requirements Links from Views

1. Navigate to > . A Requirements Toolbox™ license is required. The Requirement Links tab appears at the bottom of the Software Component Review view.
2. Select the Lighting Controller component and observe the linked requirement Automatically turn off headlights.
   
3. Select the requirement Automatically turn off headlights to open the Requirements Editor to view or modify requirement links.
4. In the Architecture Views Gallery, navigate to > if the Requirements Editor is not open already.
5. Select the Should unlock door requirement.
6. Return to the Architecture Views Gallery. In the Software Component Review view, select the Lighting Controller component.
7. Navigate to > . The new requirement Should unlock door is added.
   
8. To remove a requirement link, select and confirm deletion.

Add Custom Clauses to Component Filters and Port Filters

1. Select > to create a new view.
2. In View Properties on the right pane, in theName box, enter a name for this view, for example,Hardware Component View. Choose aColor and enter a Description, if necessary.
3. In the bottom pane on View Configurations, from theFilter tab, select from the list > to enter a constraint by which to filter. In the box, entercontains(Property('Name'),'Dashboard').
4. In the bottom pane on View Configurations, from theFilter tab, select from the list > to enter a constraint by which to filter. In the box, entercontains(Property('Name'),'sound').
5. Select .
   
   The view is filtered using the constraints in the custom filters. For more information on structuring constraints, see systemcomposer.query.Constraint.
