EMC Simulation of Automotive Ethernet

The demand for high speed data transmission between electronics systems in modern vehicles has experienced a dramatic increase over the past years. The current generation of infotainment and ADAS systems already requires high data rates that are projected to grow even further in the future, fueled by trends like the upcoming introduction of connected and autonomous vehicles.

Automotive ethernet based on the BroadR-Reach technology is a promising candidate to become the standard high speed interface in vehicles. The current implementation offers a data rate of 100 Mbit/s over a single unshielded twisted pair cable, with plans to further increase it to 1000 Mbit/s. Unshielded twisted cables are lightweight and cost effective, however this comes at the cost of reduced EMC performance. The high data rates and the cable layout can pose significant challenges on designers of automotive electronics. This eSeminar will present simulations of EMC related aspects of the automotive ethernet: the effect of the PCB layout on the emission from an automotive ethernet channel, crosstalk from the automotive ethernet channel to other cables inside one harness, and susceptibility of the channel based on the BCI testing method.
