CAN Bus in Control, Automotive and Satellites
summary
Thirty years of tooling and code are now open source: a synthesizable CTU CAN FD IP core (VHDL) that runs in FPGAs, has been ported toward ASIC, and is already used in scientific satellite payloads; a QEMU-based CAN emulation merged upstream so software can exercise real bus scenarios; and a latency testbench that adds 10 nanoseconds time-stamping to SocketCAN drivers and runs daily against mainline and PREEMPT_RT kernels, proving sustained real-time I/O up to 30 kHz on PREEMPT_RT while finding and tracking regressions.
