MotivationChallenges in Development of ECU DiagnosticsConditions: 3Complex diagnosticdescriptions Multiple variants Many change requests Tough developmentschedules Multiple different physicallayers involving gateways Bad HW availability inearly development stages Customer Expectations: Good ECU SW quality Early availability ofdiagnostic tests High test coverage Comprehensive testdocumentation
MotivationHow to meet the customer’s expectations? Automate tests and reuse test cases Solutions: Test Feature Set of CANoe, vTESTstudio, Option DiVa Work on the highest possible level of abstraction Solution: Write tests on Diagnostics Layer instead on Physical Layer Ad-hoc troubleshooting on Diagnostics LayerDo things as early as possible (“Frontloading”) Solution: Develop tests using a simulated ECU (no HW necessary) 4Easy porting on another physical layer, e.g. from CAN to Ethernet/DoIPDon’t care about the bits and bytes when the diagnostic description changesHigh level commands in vTESTstudio e.g. for fault memory testingAnalyze efficiently Solution: CANoe Diagnostic Windows (Console, Fault Memory, ) Reproducible automated diagnostic tests with the built-in CANoe functionalityFrom very flexible manual test creation to fully automated test generationEasy possibility to verify the test system and the tests in advanceReliable test results directly after replacing the simulated ECU by real HW

Diagnostics in CANoeFeature OverviewCANoeExternal controlGUIPanelsCOMXIL-API / fflineMatlab/Simulink OSEK/ AUTOSAR EmulationConsoleDiVaSession controlOBD-IIFault memory windowTest modulesTest unitsXCP/CCPExtensions (OEM specific, J1939, BAP, CANopen, AUTOSAR, .)VN26xxMOST6VN56xxBroadRReachXL-Family, /DIOSensor buses
Diagnostics in CANoeUse case: Ad hoc troubleshooting / Diagnostics ExpertChallenge:Interactively access ECU fault memory;diagnostic description (CDD, ODX/PDX,MDX) is provided by OEMSolution:7 Connect ECU to network interface Add diagnostic description tocorresponding network via“Diagnostics/ISO TP ”configuration dialog (Optionally) Modify communicationparameters (Request/Resp. IDs,P3Time, ) Open Diagnostics Console & FaultMemory window to interactivelyaccess defined services
Diagnostics in CANoeUse case: Perform repetitive processes / Domain SpecialistChallenge:Access to complex sequences ofdiagnostic services & parameters viacustomized graphical user interface fore.g. in-vehicle testingSolution:8 Map diagnostic description as before Create CAPL node Map (conditional) sequences ofdiagnostic services to one key/UIcontrol - sequencing & conditionhandling done in CAPL node Evaluate diagnostic responses inCAPL and present data on customGUI using panels, trace, data &graphic windows
Diagnostics in CANoeUse case: Test the tester / Production or Service ExpertChallenge:Observe communication betweenDiagnostic Tester and ECU todetect/analyze anomaliesSolution:9 Map diagnostic description as before Configure usage of diagnosticdescription as “Interpretation only” in“Diagnostics/ISO TP ” configurationdialog Analyze high-level diagnosticsinterpretation of physical networkmessages in trace window(diagnostics observer events)CAN/LIN/MOST/FlexRay/K-Line/Ethernet
Diagnostics in CANoeUse case: Quality assurance / TesterChallenge:Development setup (simulated ECU)Develop diagnostic tester for plannedECU; Tester needs to be finished, fullyoperational and work correctly when ECUprototype is provided later to test againstCANoeTest implementationImportsimulated busmonitorSolution: 10Use integration with CANoe’s TestFeature Set to call/execute diagnosticfunctions and tests patternsUse CANoe’s Diagnostic Feature Set tocheck interface implementation(“syntax”), failure detection(“semantics”) and robustnessSimulate ECU core diagnostic functionsin CANoe to allow for parallel tester &real ECU development, verifying thetester by introducing errors in thesimulated ECUECU TestSpecificationVirtual total systemMDXIntended final test setup (real ECU)ODX/PDXCANoemonitorCDDphysical bussimulated busVirtual partialsystemReal partialsystemImport
