        Wow! I had no idea it is so simple to add a Microcontroller into FPGA. Thank you very much Adam Taylor for great and practical step by step tutorial about how to do it. This tutorial can be useful for beginners or when starting with FPGA. Includes also DDR3, USB UART, VHDL block, Logic Analyzer and how to write Hello word software for the microcontroller.
