Model of CAN FD Communication Cotroller for QEMU Emulator

Original language description

This contribution allows to develop complete automotive and industrial systems with CAN FD communication before final target hardware is available or without need to have it available for each developer. The initial CAN emulation developed during Google Summer of Code project mentored by Pavel Pisa was accepted in QEMU mainline in 2018. The followup projects with students and employees of CTU FEE led to development of own CAN FD controller design and QEMU function model emulator for this CAN FD controller. More on this and other FEL CAN projects at http://canbus.pages.fel.cvut.cz/ During 2019 and 2020 led and supported by Pavel Pisa have implemented QEMU emulation for CTU CAN FD. Work is documented in Jan Charvat's the bachelor theses Model of CAN FD Communication Controller for QEMU Emulator and has been accepted into QEMU mainline https://git.qemu.org/?p=qemu.git&a=search&h=HEAD&st=author&s=Jan+Charvat At the same time, his work is already being followed up by developers at Xilinx who are working on emulation of CAN controller of Versatile platform (probably the world's largest processor+FPGA chip). see the reference to our project in their project fork till accepted into mainline https://github.com/Xilinx/qemu/blob/master/hw/net/can/xlnx-versal-canfd.c User Documentation Xilinx Quick Emulator User Guide - QEMU describes the use of our solution in Chapter 3 - QEMU Quick Reference Card Using CAN with Xilinx QEMU https://www.xilinx.com/support/documentation/sw_manuals/xilinx2020_1/ug1169-xilinx-qemu.pdf
