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.
