    查找 WCET 小于或等于 5 ms 的所有组件。

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

    您可以为自动单位转换指定单位。

    con5 = PropertyValue("AutoProfile.SoftwareComponent.WCET") <= Value(5,'ms');
query1Comps = model.find(con5)
    query1Comps = 3×1 cell
    {'KeylessEntryArchitecture/Sound System/Sound Controller'        }

    查找所有 WCET 大于 1 ms 或成本大于 10 USD 的组件。

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