Architecture Views Gallery

Create and manage architecture views and sequence diagrams

Description

The Architecture Views Gallery allows you to create filtered and freeform architecture views and author sequence diagrams.

Use the View Configurations options to specify component and port filters for views, and to specify grouping criteria. Click and drag components from the Model Components browser to specify the contents of a freeform view. Select views from the View Browser and use the Component Properties options to specify a name, color, and description for a view.

Switch between these types of view diagrams:

• Component Diagram — Display components, ports, and connectors based on how the model is structured.

• Component Hierarchy — Display components in tree form with parents above children. In a component hierarchy view, each referenced model is represented as many times as it is used.

• Architecture Hierarchy — Display unique component architecture types and their relationships using composition connections. In an architecture hierarchy view, each referenced model is represented only once.

• Class Diagram — Display unique architecture types of the software components optionally with software methods and properties, only available for software architecture models.

You can also link and edit requirements for views through the Architecture Views Gallery.

To create a new sequence diagram, click New > Sequence Diagram. Select existing sequence diagrams from the View Browser and use the Sequence Diagram Properties options to specify a name for the sequence diagram. To add a lifeline, click and drag from the Model Components browser. Alternatively, select Component > Add Lifeline from the menu and click the down arrow to select a component to be represented by the lifeline. Click and drag from the vertical dotted lines coming down from one lifeline to another to author a message that represents a connection between two ports. To confirm the consistency of the sequence diagram, click Check Consistency. Then, either push changes to the architecture by clicking Create in Architecture, or pull changes in from the architecture to the sequence diagram by clicking Repair.

Delete — Delete currently selected diagram

button

Delete the currently selected view or sequence diagram.

Print — Print sequence diagram

button

Print the currently selected sequence diagram to a file.

Run Query — Refresh currently selected view

button

Refresh the currently selected view with changes in the composition and rerun the corresponding filter, if it exists.

Add — Add selected component to view

button

Add the selected component in the Model Components browser to the current view diagram.

If the view is a filtered view, a prompt appears to convert the filtered view to a freeform view.

Remove — Remove selected component from view

button

Remove a selected component in a view from the current view diagram.

If the view is a filtered view, a prompt appears to convert the filtered view to a freeform view.

Group — Group selected components in view

button

Group the selected components in a view.

Ungroup — Ungroup selected components in view

button

Ungroup the selected components in a view.

Pivot — Pivot to other views selected component appears in

button

Pivot to other views in which the selected component appears. Select the view to pivot to using the drop-down list.

Display Depth — Modify number of levels of hierarchy to display

Deep (default) | Shallow

Modify the number of levels of hierarchy to display. Deep includes more levels and Shallow includes fewer levels.

Add Lifeline — Insert new lifeline into sequence diagram

button

Create a new lifeline after the selected lifeline by default by clicking Add Lifeline, or click the drop-down arrow to choose Add Lifeline > Insert After. Create a new lifeline before the selected lifeline by selecting Add Lifeline > Insert Before. Create a new lifeline nested under the selected lifeline by selecting Add Lifeline > Add Child.

Add Operand — Insert new operand into sequence diagram

button

Create a new operand after the selected operand by default by clicking Add Operand, or click the drop-down arrow to choose Add Operand > Insert After. Create a new operand before the selected operand by selecting Add Operand > Insert Before.

Check Consistency — Check whether elements in sequence diagram are consistent with architecture model

button

Check that all the elements in the current sequence diagram are consistent with the architecture model. If any of the elements in the sequence diagram are inconsistent, clicking Check Consistency highlights those elements in yellow.

Architecture Element — Specify different associated element in architecture model for selected elements in sequence diagram

component | port

Specify a different associated element in the architecture model for the selected elements in the sequence diagram.

Create in Architecture — Create elements in architecture model

button

Create elements in the architecture model for each of the selected inconsistent elements in the sequence diagram.

Repair — Update selected elements so sequence diagram is consistent with architecture model

button

Update the selected inconsistent elements in the sequence diagram so the sequence diagram is consistent with the architecture model.

Programmatic Use

openViews(model)

openViews(model) opens the Architecture Views Gallery from the MATLAB Command Window.

More About

View

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:

• Operational views demonstrate how a system will be used and should be integrated with requirements analysis.

• Functional views focus on what the system must do to operate.

• Physical views show how the system is constructed and configured.

Element Group

An element group is a grouping of components in a view.

Use element groups to programmatically populate a view.

Query

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.

Component Diagram

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.

Hierarchy Diagram

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:

• Component hierarchy diagrams display components in tree form with parents above children. In a component hierarchy view, each referenced model is represented as many times as it is used.

• Architecture hierarchy diagrams display unique component architecture types and their relationships using composition connections. In an architecture hierarchy view, each referenced model is represented only once.

Class Diagram

A class diagram is a graphical representation of a static structural model that displays unique architecture types of the software components optionally with software methods and properties.

Class diagrams capture one instance of each referenced model and show relationships between them. Any component diagram view can be optionally represented as a class diagram for a software architecture model.

Sequence Diagram

A sequence diagram is a behavior diagram that represents the interaction between structural elements of an architecture as a sequence of message exchanges.

Use sequence diagrams to describe how the parts of a static system interact.

Lifeline

A lifeline is represented by a head and a timeline that proceeds down a vertical dotted line.

The head of a lifeline represents a component in an architecture model.

Message

A message includes a send event and a receive event. You can draw messages from one lifeline to another on the vertical dotted lines in a sequence diagram. Messages are clarified with a message label.

A message label has a trigger and a constraint. A trigger determines whether the message occurs. A constraint determines whether the message is valid.

Fragment

A fragment indicates how a group of messages within are executed or interact in a sequence diagram.

A fragment is used to model complex sequences, such as alternatives, in a message-based behavior diagram.

Operand

An operand is a region in a fragment. Fragments have one or more operands depending on the kind of fragment. Operands can contain messages and additional fragments.

Each operand can include a constraint to specify whether the messages inside the operand execute. You can express the precondition of an operand as a MATLAB Boolean expression using the inputs of any lifeline.
