Abstract

Automotive industry is transitioning from slow communication over CAN bus to fast communication over Automotive Ethernet needed by cameras, radars, lidars and similar sensors. Manufacturers need a device for complex cyber security testing of new vehicles which could capture and modify frames on multiple Automotive Ethernet links at the same time. The goal of my bachelor thesis is to create such a device. There are three main requirements for this device. First, it should forward Ethernet frames between pairs of Automotive Ethernet ports (either 100BASE-T1 for 100 Mb/s Ethernet or 1000BASE-T1 for 1 Gb/s Ethernet). Second, it should log the traffic via the CMP protocol to the DAQ port (implemented using SFP+ module for up to 10 Gb/s Ethernet). Third, it should support time synchronization via the PTP protocol on the Automotive Ethernet ports. The AMD Kria platform built on the Zynq UltraScale+ system on chip has been chosen for implementation of the device. For better performance, forwarding and logging will be implemented in hardware using the programmable logic. On the other hand, time synchronization and configuration will be implemented in software using the processing system. My thesis describes the whole design process starting with learning the relevant technologies and ending with testing the device in a real environment. In the first part, the hardware design is discussed, verified in simulation and implemented on the target platform. In the second part, the software design is discussed and built for the target platform. Finally, both parts are validated together in more complex tests.
