Automotive Ethernet Device and Network Testing

10BASE-T1S technology was developed as part of the IEEE 802.3cg-2019 standard to enhance in-vehicle Ethernet networks by providing Ethernet-to-the-edge connectivity, which is essential for zonal-based automotive architectures. It offers a cost-effective solution by utilizing a multidrop bus topology, allowing multiple devices to connect via a single unshielded twisted pair cable without the need for switches or gateways. This brief provides an overview of 10BASE-T1S technology, including related benefits, testing challenges and key testing considerations, along with setup and configuration guidelines to ensure optimal performance and reliability in both peer-to-peer and multidrop environments.

Perform rapid, reliable, and cost-effective testing at every tier of the automotive tech stack, for every player in the automotive and autonomous vehicle value chain, and at every stage in the vehicle development lifecycle.

The next-generation Ethernet standard "IEEE 802.1 TSN (Time-Sensitive Networking)" is a protocol for achieving real-time performance. Since the transmitted data can be delivered within the set time according to the priority, it is expected to be used in industrial equipment and in-vehicle networks that require precise control.
