Automotive ethernet and other bus systems

In-vehicle networks and ECU testing

Test solutions to design, debug, certify and manufacture all elements of in-vehicle networks

The development of higher levels of autonomous driving and new services delivered by automotive connectivity require high performance computers connected by in-vehicle networks with higher and higher data rates. At the same time, automotive component suppliers and vehicle manufacturers need to ensure the performance, interoperability, data integrity and security of IVNs. Our in-vehicle network test solutions ensure seamless network communication by supporting the development, debugging and validation of CPUs, ECUs, cables and connectors up to the latest multi-gigabit standards.

Features of Rohde & Schwarz in-vehicle network and ECU testsolutions:

Test solutions for all parts of in-vehicle networks including HPC, domain controllers, zonal controllers, cables, busses and connectors
Trigger and decode capability for CAN, CAN-FD, LIN, FlexRay, CXPI, SENT, 100BASE-T1 and 1000BASE-T1
Compliance tests for automotive Ethernet (10BASE-T1S, 100BASE-T1, 1000BASE-T1, 2.5/5/10GBASE-T1 ) in accordance with standards such as 802.3cg, 802.3bw, 802.3bp, 802.3ch
Channel and Connector testing (100BASE-T1, 1000BASE-T1, 2.5/5/10GBASE-T1) according to OPEN Alliance TC9
EMI debugging, IVN signal & power integrity verification and analysis

"Automotive Ethernet is now widely introduced in cars. In the OPEN Alliance, the industry has defined specific compliance tests. We offer a complete compliance test solution for 100BASE-T1 and 1000BASE-T1 that is widely accepted by OEMs, Tier 1s and test houses. With the new triggering and decoding solution for 100BASE-T1, automotive Ethernet can now be debugged the same way as the traditional CAN bus."

Ralf Oestreicher

Modern vehicles typically have more than 100 electronic control units (ECUs), connected via various in-vehicle networks such as CAN, FlexRay, LIN, and Ethernet. These busses are used to exchange information and coordinate control. The higher volume of data generated by the rapid increase of sensors to support autonomous driving creates a demand for much higher data rate traffic within vehicles and today we have reached MultiGigabit Ethernet speeds. Of course, the data supports safety-critical functions so its integrity must be ensured. To verify the functionality of these data streams as well as the cables, domain controllers, ECUs and all parts of the in-vehicle networks, automotive engineers need to be able to search for specific signals, trigger, decode, measure crosstalk and perform standards compliance testing.
