Compliance test facilitates auto Ethernet roll-out

February 04, 2016 // By Christoph Hammerschmidt
Automotive electronics services provider Ruetz Systems Solutions (Munich, Germany) has developed the world’s first compliance verification process for electronic control units that make use of the Ethernet networking technology.

The process meets the TC-8 test specs of Open Alliance, an industry group that promotes the utilisation of Ethernet in the car. In automotive electronics, Ethernet increasingly becomes the technology of choice to interconnect infotainment and other time-critical data rich applications.

“The implementation of IP/Ethernet technology in vehicles is approaching rapidly, and therefore it becomes important for OEMs to have high-quality, cost-effective test procedures available”, explained co-founder and general manager of Ruetz System Solutions. “With Ethernet, we will see massive changes for the system specification of the entire data communications infrastructure in the cars. Tier one and tier two suppliers are facing the challenge of implementing these requirements reliably and on time”.

The Ethernet compliance verification process includes standardised test methods to align the new automotive standards with existing proven and stable systems. Towards this end, the compliance verification process provides the ecosystem to verify components and control units and thus facilitates the entry to the Ethernet technology for OEMs and suppliers.

The process covers the entire relevant test scope. The layer 1 (PHY) tests include interoperability tests and PMA. For layer 2 (MAC) tests, Ruetz offers VLAN, QoS and general switching as well as Ingress filtering and error diagnosis. The TCP/IP protocol family contains address resolution protocol (ARP), Internet control messages protocol version 4 (ICMPv4), IPv4 dynamic local link address configuration, user datagram protocol, and DHCP $ as well as TCP, SOME/IP and SOME/IP SD.
