OEM Considerations

OEM Considerations

u General Motors

u DiVa with custom GMW3110 Node Verification Procedures extensions accepted for validation> ~80% automated testing

> ~15% user interaction (e.g., DTC setting, Turning ECU off and on again, etc.)

> ~5% agreed not to be tested (EEPROM failure, incomplete ECU programming states, etc.)

u Ford

u Ford provides suppliers a custom tool called the “Script Player”

u DiVa used by some suppliers for early debugging

u FIAT Chrysler Automobiles (FCA)

u DiVa extensions for PowerNet tests according to sd11468

u DiVa extensions for FIAT tests according to Z0059, Z0059-1, Z0071 & Z0145

u Utility available to populate DVR sheet from DiVa results

22

OEM Considerations

OEM Considerations

u Daimler

u DiVa extensions available for MBN 10746 & MBN 10747

u Volkswagen Group

Addressing the Issues

Benefits

u Inconsistent testing methodologies don’t ensure ECU compatibility

u The same test patterns can be applied across all ECUs

u OEMs can specify a DiVa configuration template for consistency

u Manually run tests are time consuming & costly

u Test execution automated in CANoe with optional levels of hardware automation (Batt & Ign control >> Full HIL interface for DTC & application validation)

u Interpretation & debugging of test results is difficult

u All results linked to CAN trace log and source CDD/ODX data

u Sorting, commenting & export capabilities in DiVa reports

u Poor supporting documentation for quality reviews/audits

u Complete HTML test specification generated

u Complete & detailed test report in HTML or XML format

u Test case mapping to requirements possible
