Automotive Ethernet Testing and Development Achieving Quality and Interoperability through Standardized Tests

Automotive Safety Matters Many fear airplanes but vehicles are much more dangerous Automotive safety saves lives 224 fatalities (2013) 1.25 million fatalities (2013) (one square = 250 fatalities worldwide)

Cars are Getting Safer Great improvements have been made Vehicle technology is a big part of these improvements Testing is a critical part of the improvement process Annual fatalities in the US have gone down roughly 40% from their peak in the early 1970s… … and taking into account increases in driving, the reduction is even more significant

Automotive Emissions Matters

Cars are also Getting Greener… Vehicle makers have responded to concerns over global warming and smog-related health issue by dramatically reducing emissions Finely-tuned emission control systems require advanced technology, and in turn, better testing products and methodologies

Autonomous Driving – The Future is Now!

State of Ethernet in Cars: TOO BIG TO FAIL!! Many production plans in place (freight train a running)

Ethernet vs. CAN

Vehicle Network Traffic Growth 202924 B/s 2016 Ethernet 16474 B/s 2013 Many CAN 5440 B/s 2004 CAN 2004 2007 2010 2013 2016

Why Standardized Testing? Promotes efficiency More companies / people involved the better coverage and maturity is achieved Standardized testing can reduce manufacturer liability AVB / TSN Suite TCP/IP Suite

Audio/Video Bridging (AVB) / Time-Sensitive Networking (TSN) Ethernet is designed to just send packets quickly, not in a deterministic or consistent manner AVB (later renamed TSN) defines a set of protocols that allow high-quality audio and video streaming over standard Ethernet (including BroadR-Reach) Implemented in AVB-aware bridges and endpoint devices Key elements: Clock synchronization (gPTP) Mechanism for defining streams and reserving network bandwidth (SRP) Traffic shaping algorithm for steady data delivery (FQTSS) Special transport protocol for A/V data (AVTP)

RAD-Galaxy: Key Features Open Alliance TC2 and Broadcom approved EMC connectors Gigabit Ethernet to the PC 10 ns Timestamp accuracy across all Nets enough for most advanced IEEE features 8x CAN-FD 6x Active TAPs 1x LIN MICS / IO Automotive Power Supply (5.5v – 40v) Extruded aluminum Enclosure Automotive Grade Temperature range -40 to +85 DegC

Future Rapidly Developing IEEE 802.1Qbu – Frame Preemption IEEE 802.1Qbv – Time Aware Scheduler RAD-Galaxy’s FPGA (SoC) can be upgraded with no HW changes to support advanced functionality.

…100% of them are affected by vehicle safety and emissions. Summary …100% of them are affected by vehicle safety and emissions. Nearly 4 billion people live in city centers… Automotive testing matters! Automotive Ethernet is going to be a big part of the solution for future emissions and safety improvements but its more complicated than CAN. Standardization in testing can improve efficiency and reduce liability. Your work affects billions of people so do it well.
