Create Architectural Views Programmatically

You can create an architecture view programmatically. This topic presents two examples of creating architecture views programmatically using a keyless entry system architecture using element groups.

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

Use element groups to programmatically populate a view.

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

The third example is about how to use queries to find elements in a System Composer™ model.

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.

Create Architecture Views in System Composer with Keyless Entry System

Use a keyless entry system to programmatically create architecture views.

1. Import the package with queries.

import systemcomposer.query.*

2. Open the Simulink® project file for the Keyless Entry System.

scKeylessEntrySystem

3. Load the example model into System Composer™.

model = systemcomposer.loadModel("KeylessEntryArchitecture");

Example 1: Hardware Component Review Status View

Create a filtered view that selects all hardware components in the architecture model and groups them using the ReviewStatus property.

1. Construct a query to select all hardware components.

hwCompQuery = HasStereotype(IsStereotypeDerivedFrom("AutoProfile.HardwareComponent"));

2. Use the query to create a view.

model.createView("Hardware Component Review Status",...
 Select=hwCompQuery,...
 GroupBy={'AutoProfile.BaseComponent.ReviewStatus'},...
 IncludeReferenceModels=true,...
 Color="purple");

3. To open the Architecture Views Gallery the Views section, click Architecture Views.

model.openViews

Example 2: FOB Locator System Supplier View

Create a freeform view that manually pulls the components from the FOB Locator System and groups them using existing and new view components for the suppliers. In this example, you will use element groups, groupings of components in a view, to programmatically populate a view.

1. Create a view architecture.

fobSupplierView = model.createView("FOB Locator System Supplier Breakdown",...
    Color="lightblue");

2. Add a subgroup called Supplier D. Add the FOB Locator Module to the view element subgroup.

supplierD = fobSupplierView.Root.createSubGroup("Supplier D");
supplierD.addElement("KeylessEntryArchitecture/FOB Locator System/FOB Locator Module");

3. Create a new subgroup for Supplier A.

supplierA = fobSupplierView.Root.createSubGroup("Supplier A");

4. Add each of the FOB Receivers to view element subgroup.

FOBLocatorSystem = model.lookup("Path","KeylessEntryArchitecture/FOB Locator System");

Find all the components which contain the name "Receiver".

receiverCompPaths = model.find(...
    contains(Property("Name"),"Receiver"),...
    FOBLocatorSystem.Architecture);

supplierA.addElement(receiverCompPaths)

5. Save the model.

model.save

Find Elements in Model Using Queries

Find components in a System Composer model using queries.

Import the package that contains all of the System Composer queries.

import systemcomposer.query.*

Open the model.

scKeylessEntrySystem
model = systemcomposer.loadModel("KeylessEntryArchitecture");

Find all the software components in the system.

con1 = HasStereotype(Property("Name") == "SoftwareComponent");
[compPaths,compObjs] = model.find(con1)
compPaths = 5x1 cell
    {'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'}
    {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }
    {'KeylessEntryArchitecture/Lighting System/Lighting Controller'           }
    {'KeylessEntryArchitecture/FOB Locator System/FOB Locator Module'         }
    {'KeylessEntryArchitecture/Sound System/Sound Controller'                 }

compObjs=1×5 object
  1x5 Component array with properties:

    IsAdapterComponent
    Architecture
    ReferenceName
    Name
    Parent
    Ports
    OwnedPorts
    OwnedArchitecture
    Position
    Model
    SimulinkHandle
    SimulinkModelHandle
    UUID
    ExternalUID

Include reference models in the search.

softwareComps = model.find(con1,IncludeReferenceModels=true)
softwareComps = 9x1 cell
    {'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'                                }
    {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller'                                 }
    {'KeylessEntryArchitecture/Lighting System/Lighting Controller'                                           }
    {'KeylessEntryArchitecture/FOB Locator System/FOB Locator Module'                                         }
    {'KeylessEntryArchitecture/Sound System/Sound Controller'                                                 }

    {'KeylessEntryArchitecture/Door Lock//Unlock System/Front Driver Door Lock Sensor/Detect Door Lock Status'}

Find all the base components in the system.

con2 = HasStereotype(IsStereotypeDerivedFrom("AutoProfile.BaseComponent"));
baseComps = model.find(con2)
baseComps = 18x1 cell
    {'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'          }
    {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller'           }
    {'KeylessEntryArchitecture/Lighting System/Lighting Controller'                     }
    {'KeylessEntryArchitecture/FOB Locator System/FOB Locator Module'                   }
    {'KeylessEntryArchitecture/Sound System/Sound Controller'                           }

    {'KeylessEntryArchitecture/Door Lock//Unlock System/Rear Pass Door Lock Actuator'   }
    {'KeylessEntryArchitecture/FOB Locator System/Center Receiver'                      }
    {'KeylessEntryArchitecture/FOB Locator System/Front Receiver'                       }
    {'KeylessEntryArchitecture/FOB Locator System/Rear Receiver'                        }

Find all components using the interface KeyFOBPosition.

con3 = HasPort(HasInterface(Property("Name") == "KeyFOBPosition"));
con3_a = HasPort(Property("InterfaceName") == "KeyFOBPosition");
keyFOBPosComps = model.find(con3)
keyFOBPosComps = 10x1 cell
    {'KeylessEntryArchitecture/Door Lock//Unlock System'                      }
    {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }

Find all components whose WCET is less than or equal to 5 ms.

con4 = PropertyValue("AutoProfile.SoftwareComponent.WCET") <= 5;
model.find(con4)
ans = 1x1 cell array
    {'KeylessEntryArchitecture/Sound System/Sound Controller'}

You can specify units for automatic unit conversion.

con5 = PropertyValue("AutoProfile.SoftwareComponent.WCET") <= Value(5,'ms');
query1Comps = model.find(con5)
query1Comps = 3x1 cell
    {'KeylessEntryArchitecture/Lighting System/Lighting Controller'  }
