汽车以太网设备及网络测试

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.

了解10BASE-T1S以太网如何提供新的优势，使其非常适合广泛的汽车应用，其中包括跨多个领域的传感器与执行器。

Watch the demo to see how Spirent TTsuite-OPEN-EthernetSwitch enables users to validate the compliance of an Ethernet switch as part of an in-vehicle network.

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. Watch the video to see a demonstration of Ethernet TSN switch conformance testing using Spirent Automotive C1 by [Renesas Electronics Corporation](https://www.renesas.com/jp/en/blogs/ethernet-tsn-switch-ip-core-evaluated-conformance-testing-provided-spirent-communications)

GAC Motor develops and verifies their automotive Ethernet systems with Spirent test automation tools to deliver new in-car capabilities, because high-quality networks require high-quality testing. To guarantee flawless in-vehicle and V2X communication, compliance to standards developed by nonprofit organizations such as OPEN Alliance SIG and Avnu are required for building a complete ecosystem of interoperable devices. Read this case study to learn how Spirent assisted Hyundai design team in their efforts to determine the best Ethernet designs, to ensure their next-generation automobile conforms to IP and AVB standards.
