PS2 Keyboard interface runs smoothly in Active-HDL simulator, but not working on Nexys2 Board

I have to make a PS2 Keyboard Controller project at the university and i encountered a few problems when trying to test the system on the FPGA board.

It had worked perfectly in the simulator of Active-HDL, but i am not sure what it might be that stops it from working on the board, because when i try to program the board, the .bit file gets uploaded, but it does not react when i plug the PS/2 Keyboard in it and try to press a key.

I thought that probably a problem might be related to the PS/2 Keyboard protocol or the way it is synthesized for the board, but i really do not know.

The source code is here https://wetransfer.com/downloads/1d000a9feb241ff84693fca2084b0e9a20180513165005/8f7ca4 and the top level is called "ps2_top_src". I am sorry for the way of uploading the code, but i couldn`t make it upload anywhere else.
