-Open-source CAN FD core+
  
-The Czech Technical University (CTU) in Prague has developed an open-source CAN FD core and appropriate development tools. The core complies with ISO 11898-1:2015. The IP core is available under MIT license conditions. The basic features include a RX first-in, first-out (Fifo) buffer of 32 words to 4 096 words equivalent to one to 204 CAN FD data frames and four TX buffers for one CAN FD data frame each. Time stamping of frames is supported as well as time-triggered transmission of data frames.+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.
