AVR microprocessor core implementation in Altera MAX-II FPGA

I want to share with you my experience of developing a microprocessor. I wanted to make my microcontroller as simple as possible with a minimal system of commands. If you make your microcontroller, then you need your assembler ...
After some thought, I decided that in this sense it would be easier to follow some well-known command system. Stopped on the AVR8.
What came out of this can be read here (Open Source Hardware Project).
