    Find components in a System Composer model using queries.

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

    import systemcomposer.query.*

    Open the model.

    openProject("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

    Find all the base components in the system.

    con2 = HasStereotype(IsStereotypeDerivedFrom("AutoProfile.BaseComponent"));
    baseComps = model.find(con2)
    baseComps = 18x1 cell
        {'KeylessEntryArchitecture/Door Lock//Unlock System/Front Pass Door Lock Actuator'  }

    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/Sound System'                                  }
        {'KeylessEntryArchitecture/Sound System/Sound Controller'                 }
        {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }
        {'KeylessEntryArchitecture/FOB Locater System'                            }
        {'KeylessEntryArchitecture/FOB Locater System/FOB Locater Module'         }
        {'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'}
        {'KeylessEntryArchitecture/Lighting System/Lighting Controller'           }
        {'KeylessEntryArchitecture/Lighting System'                               }
        {'KeylessEntryArchitecture/Door Lock//Unlock System'                      }
        {'KeylessEntryArchitecture/Engine Control System'                         }
    
    

    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/Sound System/Sound Controller'        }
        {'KeylessEntryArchitecture/Lighting System/Lighting Controller'  }
        {'KeylessEntryArchitecture/FOB Locater System/FOB Locater Module'}
    
    

    Find all components whose WCET is greater than 1 ms or that have a cost greater than 10 USD.

    con6 = PropertyValue("AutoProfile.SoftwareComponent.WCET") > Value(1,'ms') | PropertyValue("AutoProfile.Base.Cost") > Value(10,'USD');
    query2Comps = model.find(con6)
    query2Comps = 2x1 cell
        {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }
        {'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'}
