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

Report analysis in CANoe.DiVa

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.
