Application_Area.jpg

Suppliers

Suppliers and service providers benefit from a standardized test solution that can be used in different OEM projects. Open interfaces, e.g. for requirement tracking, offer integration into existing development processes. This not only increases development efficiency and software quality, but also achieves cross-project synergies and efficiency gains. 

Vehicle Manufacturers

Vehicle manufacturers receive a comprehensive and fine-grained insight into the current quality of diagnostic implementation at an early stage of development. A standardized test report across suppliers provides support and transparency. OEM extensions are used to explicitly safeguard manufacturer-specific applications and diagnostic features (already at the supplier).

Key Features

CANoe.DiVa provides test configuration, test generation, test result analysis support accompanied by requirement traceability and automated test control.

The generator uses diagnostic descriptions in ODX or CANdela format to generate comprehensive test cases in accordance to the configured test depth (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 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, requirement linking and post processing of tests and test results. Comments and requirements given by the user are persistently stored over sequential test runs.

OBD Tests

CANoe.DiVa automatically executes specific tests for OBD-capable ECUs at an early stage, as required and mandatory for the final vehicle acceptance test.

  • Early testing of the OBD2, OBDonUDS, ZEVonUDS or WWH-OBD protocol as well as the correct activation of the MIL (malfunction indicator lamp)
  • Automated execution of PVE (Production Vehicle Evaluation) test sequences
  • Automated execution of conformance tests in accordance with SAE J1699-3/-5 at ECU level

Protocol Validation

  • 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

Support of SOME/IP

Automated test generation & execution for all SOME/IP services and operations of an SUT:

  • Test generation based on AUTOSAR XML and Franca IDL
  • Support of all SOME/IP basic operations: “Find”, “Offer”, “Subscribe”, “Methods”, “Events” & “Fields”
  • Test of availability and correctness of all services
  • Test in combination with operating states, e.g. ignition on/off
  • Definable expected values, e.g. specific parameter values

Validation of Diagnostic Sequences

With CANoe.DiVa you can test ECU-specific diagnostic sequences in freely selectable system states (e.g. ignition on/off). Any diagnostic sequences from applications based on the ISO 22900-2 (D-PDU API) are supported - and of course all sequences implemented in VDS (Vector Diagnostic Scripting).

  • Continuous testing of diagnostic sequences and (D-PDU API) diagnostic systems within the CANoe test environment using CANoe‘s environment stimulation capabilities.
  • Evaluation and documentation of outputs of diagnostic sequences in the test report.
  • Checking of used diagnostic services against diagnostic specification: e.g. timing behavior, format, data contents.
  • Simple and fast setup of self-defined diagnostic sequences in VDS, e.g. via the CANoe Macro Recorder or the Indigo Script Recorder. Self-generated VDS scripts or sequences can also be used easily.

Validation of the Application: Diagnostic Parameter and Fault Memory

  • 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
  • Provoke and reset error states automatically (network signal errors or electrical errors via VT System or other HIL)
  • Comprehensively check proper DTC setting, resetting and reporting, according to protocol and specification

Software Download Test

Validation of the flash programming of ECUs in conjunction with vFlash and D-PDU API based diagnostic testers. CANoe.DiVa can generate tests for the bootloader supported by vFlash. Vector offers prepared vFlash Templates for a large number of different automotive OEMs and bootloaders.

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

  • Valid flashing and testing of diagnostic communication 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

Requirements Mapping

  • Creation of requirements or import of requirements from requirements systems (e.g., Doors) or test data management systems using the Vector Connection Utilities/AddIn of vTESTstudio
  • 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 requirement or test data management system
  • Automated control of CANoe.DiVa for integration into an existing build and test environment (e.g. Jenkins or Subversion)

Security

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

Continuous Testing

Automated execution of CANoe.DiVa test cases in a virtual SW environment (Software in the Loop | SiL) or on the test bench (Hardware in the Loop | HiL)

Instead of manually reviewing large volumes of findings, CANoe.DiVa helps identify similar error situations and group them with one consolidated comment.

AI-supported capabilities include in detail:

  • Automated analysis and commenting of test results
  • Grouping of similar error situations
  • Support for precise explanations based on requirements and OEM specifications
  • Automated requirement linking and traceability
  • Use of requirement information, diagnostic data, and test setup information
  • Automated configuration of extended test information e.g. as input for DTC testing

The result: faster evaluation, clearer traceability, and a stronger connection between requirements, test configuration, and test evidence.

Automated Testing for Service-Oriented Vehicle Diagnostics

SOVD is a key enabler for Software-Defined Vehicles (SDVs) and future vehicle diagnostics - and CANoe.DiVa 20 is ready to support you on this path.

With the new SOVD test support, CANoe.DiVa 20 enables automated validation of SOVD resource based on OpenAPI descriptions. It checks interface completeness, verifies protocol conformity, and validates diagnostic communication between HPCs, gateways, and UDS-based embedded ECUs.

CANoe.DiVa 20 supports three powerful SOVD testing perspectives:

  • Pure Interface Test
    Generate tests based on OpenAPI descriptions and validate the SOVD implementation of all available entities.
  • End-to-End Protocol Test
    Check whether diagnostic information remains consistent between SOVD and UDS communication.
  • End-to-End Application Test
    Validate whether changes in I/Os and application behavior on UDS-side are correctly reflected in SOVD values - including test setups with HIL, VT System, and CANoe Remaining Bus Simulation.

This helps you build confidence in service-oriented diagnostic architectures - from interface validation to real system behavior.

Linux Support for Test Generation in CANoe Server Edition

CANoe.DiVa 20 extends test generation to Linux environments in CANoe SE.

This gives development and validation teams more flexibility in toolchain design and enables technical advantages in automated environments - without requiring a Windows license for test generation.

For teams working with modern CI/CT pipelines, containerized environments, or software-centric validation workflows, this is an important step toward more scalable diagnostic testing.

Diagnostic Validation for Pure Software-Based Testing

With CANoe4SW .DiVa, CANoe.DiVa 20 supports pure software-based diagnostic testing.

This enables you to shift diagnostic validation earlier into the development process - even before physical hardware is available. You can test diagnostic behavior in software-centric environments and create a smoother transition from virtual validation to HiL system testing, and vehicle testing.

Compliance Testing on Vehicle Level: J1699-3 (OBD2) und J1699-5 (OBDonUDS/ZEVonUDS)

CANoe.DiVa 20 expands automated OBD compliance testing with support for J1699-3/-5 compliance tests on vehicle level.

You can now automate compliance test execution not only on component level, but also directly on the vehicle. This helps you validate OBD behavior more consistently across development stages and supports a more efficient path toward regulatory readiness.
