CTU - Czech Technical University in Prague
There are many CAN bus related project implemented at the Faculty of Electrical Engineering of the Czech Technical University in Prague
CTU CAN FD
CTU CAN FD is a soft IP core whose development started at Czech Technical University. The core is usable in FPGA and ASIC implementations. It supports ISO and NON-ISO versions of CAN FD protocol and it is compliant with ISO 11898-1 2015. The core is open-source, see the licensing conditions on project page.
HW Features:
- 2 - 8 TX buffers
- FIFO-like RX buffer with configurable size
- HW filtering of RX frames
- Time-stamping (RX) and Time-triggered transmission (TX)
- Variety of interrupts
- Listen only mode, Restricted operation mode, Self test mode, Test Mode,
- Support of ASIC manufacturing testability (DFT and memory testing)

Apart from core itself, there are several sub-projects:
- Emulation in mainline QEMU source tree. See QEMU CAN documentation.
- Socket CAN Linux driver (not part of Linux mainline at present time). See Linux driver.
Usage:
- The core has been used in several industry projects realized at: Department of measurement
OpenCores SJA-1000 FD Tol
OpenCores SJA-1000 controller modified to ignore CAN FD frames which allows it to coexists and send frames on network with CAN FD traffic. The core is packed as a Xilinx Vivado component.
