Automated Testing of Diagnostic Software in ECUs
Diagnostics
What is CANoe.DiVa?
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. CANoe.DiVa then supports
the evaluation and further processing of the test results.
Overview of 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 and bus
systems (CAN, FlexRay, DoIP, 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.
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 module that is loaded to a
CANoe test environment, as well as a test specification.
The generated tests cover both protocol and application
scope. The (re-) programming of ECUs for valid and
invalid sequences is also checked. The test results are documented in a clear report. The test analysis is supported by
CANoe.DiVa with functions for sorting, comparing, filtering, commenting and further processing of the test results.
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

Factsheet CANoe.DiVa
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
>
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
Software Download Test
Validation of ECU flash programming in conjunction with
vFlash and D-PDU based diagnostic testers. CANoe.DiVa
can generate tests for the bootloader supported by vFlash.
vFlash supports more than 120 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 flas-
hing.
Requirements Mapping
>
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
>
Automated control of CANoe.DiVa for integration into
an existing build and test environment (e.g. Jenkins or
Subversion)
Security
>
Integration of Vector Security Manager. The Vector
Security Manager provides OEM-specific security func-
tions, e.g. for diagnostic authentication.
>
Test of diagnostic authentication and service availability
Highlights of Version 14
Integration and Testing of 3rd Party Diagnostic
Procedures
>
Test of any diagnostic jobs executed via the
D-PDU API.
>
Test of timing, protocol, supported services and
expected values under freely configurable system
conditions (e.g. undervoltage).
Advantage: OEM-specific use cases from development, production, after-sales service or OTA are
tested automatically and reproducibly. The test
checks whether the ECU and the diagnostic procedure work together. Components that are not yet
available at the time of development (e.g. on-board
testers) are emulated in this way so that the test of
diagnostic procedures can take place much earlier.
Further Optimizations
>
Support of the new 60V Vector VT system modules
(VT2808, VT1104, VT7101)
>
Full support of relative paths for better localization
of the DiVa project, e.g. in continuous integration or
regression test applications
>
Optimizations in the user interface with regard to
high-resolution display and performance
>
New UDS tests: Test that only readable DIDs can
actually not be overwritten.
>
Many new OEM specific test extensions
Application Areas
Only with the help of test automation, it is possible to
secure the extensive diagnostic interfaces of ECUs. CANoe.
DiVa contributes a large part to this: The system supplier
needs extensive tests to support development as well as
regression and release tests. Automotive OEMs also need
systematic tests, especially in integration and release on
the vehicle level.
CANoe.DiVa is designed to be used by automotive OEMs
and suppliers. CANoe.DiVa is not tailored to a specific
automotive OEM, but it allows OEM specific adaptions and
extensions by configuration and/or plug-ins.
