First compliance verification process for ethernet ECUs

"The system specifications of whole board nets underlie enormous changes. Thus, Tier 1 and Tier 2 suppliers have to do their best to implement these new requirements reliably and right on time." Through the compliance verification process, the company introduces standardised test methods in order to bring new automotive standards together with reliable and stable systems. The compliance verification process provides an ecosystem for component and ECU verification and consequently simplifies the technology entry for new OEMs and suppliers.

The company has completed several milestones for compliance verification. Following the release of the first OPEN ALLIANCE TC8 test specification, the experts in automotive data communication have put into effect a complete test process over all OSI/ISO layers. All test setups are available and the test process is in practice. The first project has successfully integrated the test process into an OEM's onboard system development: at their compliance test lab, the company has effectively tested Tier 1 devices (ECUs) and Tier 2 components (FPGAs, ASICs).

The company provides compliance testing for automotive IP/Ethernet covering all relevant test scopes. Tests for layer 1 (PHY) include interoperability tests and PMA. For layer 2 (MAC) testing, the experts in data communications supply VLAN testing, QoS testing, general switch testing, ingress filtering, and diagnostics. The TCP/IP protocol family incorporates the following protocols: Address Resolution Protocol (ARP), Internet Control Message Protocol version 4 (ICMPv4), Internet Protocol version 4 (IPv4), Dynamic configuration of IPv4 Link Local Address, User Datagram Protocol (UDP), Dynamic Host Configuration Protocol version 4 (DHCPv4) and Transmission Control Protocol (TCP). For automotive protocols, SOME/IP and SOME/IP SD are part of the test portfolio.
