Hi Marc, Thanks for your response and suggestions. Yes, I'm afraid a real CAN FD traffic of a real car is still desirable to our team. This is normally a trace file (.csv or .txt) with raw data and timestamp (i.e., equivalent to .pcapng wireshark protocol captures). The idea is to mimic real components on a real CAN FD testbed that uses a CAN FD controller implemented in a FPGA controller (CTU CAN FD). The characteristics of a real CAN FD traffic is valuable for research since we don't have access to a real car with CAN FD to test with. Regards.
