With the rapid advancement in the automotive world more communication nodes are being added to the vehicle which makes it significant for test and validation engineers to log all the in-vehicle traffic reliably. Modern cars have hybrid networks comprising of conventional CAN, CAN-FD, Flexray, LIN, Analog, Serial communication, and ethernet. All those networks have to co-exist and they need to be measured efficiently. For higher requirements of bandwidth and scalability Automotive Ethernet (100BASE-T1, 1000BASE-T1, and additional speed grades coming soon) have become an important part of the vehicle’s on-board-network.’ Technica Engineering holds the longest experience in providing testing and validation tools for Automotive Ethernet. From the dawn of 100BASE-T1 (Former BroadR-Reach â„¢) in 2008 for BMW and Broadcom, Technica Engineering has pioneered the Automotive Ethernet testing landscape, handling the challenges associated with this technology for testing and validation of modern E/E systems in the vehicle. One must wonder when we have all these existing technologies in a vehicle, why do we opt for something completely different as a point to point ethernet technology? Why was it needed? And what are the challenges and corresponding solutions for dealing with this technology in the logging world?
