CANoe.DiVa - Automated Testing of the Diagnostic Protocol in ECUs

DiVa is a CANoe extension for automated testing of diagnostic software implementations in ECUs. Reproducible test cases are generated based on an ECU diagnostic description in CANdela or ODX format.

CANoe automatically executes these test cases and generates a conclusive test report.

Advantages

  • Automatic generation of test cases and their specification with comprehensive test coverage based on ECU diagnostic descriptions in ODX or CANdela format
  • Automated execution of test cases and generation of a test report
  • Supports different diagnostic standards (UDS, OBD, KWP2000, GMW3110) and OEM-specific interpretations and test specifications
  • Easy to configure test contents
  • Integration in the CANoe test environment

This means savings in time and effort while improving the quality of ECU diagnostic software at the same time.

Application Areas

Generating test cases and automating test execution are two important trends in testing. The system supplier needs extensive tests to support development as well as regression and release tests. Automotive OEMs also need syste-matic tests, especially in integration and release on the vehicle level.

CANoe.DiVa is designed to be used by automotive OEMs and suppliers. DiVa is not tailored to a specific automotive OEM, but it allows OEM specific adaptions and extensions by configuration and/or plug-ins.

Highlights Version 11.0

OBD Fault Memory Test

  • Execution of fault memory test cases according to PVE („Production Vehicle Evaluation“)
  • Checking the „Monitoring“ requirements

Security

  • Integration of Vector Security Manager. The Vector Security Manager provides OEM-specific security functions, e.g. for diagnostic authentication.
  • Test of diagnostic authentication and service availa-bility

Requirements Traceability

  • Exchange of generated test cases with popular test data management systems

Application

  • Full 64-bit compatibility

Manufacturer Support

  • Expansion and optimization of existing OEM exten-sions, e.g. in the area of security and software download.
  • New OEM extensions for further OEMs

Functions

CANoe.DiVa consists of a configuration tool with a dedicated user interface, test case generator and runtime library for extended CANoe test functionality. The generator uses diagnostic descriptions in ODX or CANdela format to generate comprehensive test cases (good and bad cases). It generates a test environment that is added to a CANoe configuration, as well as a test specification with details on the test flow and the individual tests. The generated tests cover both protocol and application scope. The (re-) programming of ECUs for valid and invalid sequences is also checked. The execution results are documented in a clear report. The analysis of the test results is supported by CANoe.DiVa with mechanisms for sorting, comparing, filtering, commenting and further processing of the test results.

  • Physical/functional addressing and timing
  • Protocol format: Processing of valid and invalid requests
  • Execution or rejection of services at various session and security levels
  • Data types and value limits

  • Parameter vs. parameter: Compare write/read
  • Compare parameters to expected values, e.g. values acquired over CCP/XCP
  • Compare parameter with I/O or network signals
  • Error states can be automatically provoked (network signal errors or electrical errors via VT System) and reset
  • Test of whether the ECU detects the error, reports it according to protocol and specification and again resets the error

Validation of the flash programming of ECUs in conjunction with vFlash. CANoe.DiVa can generate tests for the bootloader supported by vFlash. vFlash supports over 90 bootloaders (1/2017).

CANoe.DiVa generates, among others, the following tests:

  • Valid flashing and testing of diagnostic communica-tion with regard to timing and format.
  • Flashing when under / overvoltage.
  • Abort the flash sequence at different points and targeted interruption of the power supply during flashing.

  • Creation of requirements or import of requirements from requirements systems (e.g., Doors) or test data management systems
  • Generated tests can be mapped to requirements. This facilitates the tracking of the requirements
  • Display of all test results for individual requirements
  • Returning test results to the system
