All Settings are available through OSD:

• Choose color
• Choose view
• Overlay for field description 1-8,A-H
• Play against human or AI
• Select AI strength and randomness

Design is done without the use of any CPU/Processor, just pure logic in VHDL. Ressource usage is very high, as a lot of things are done in parallel:

• Finding all possible moves for a given board is done in a few clock cycles
• Executing a move(including castling and en passant) in a single cycle
• Evaluating the score of a given board for the AI costs 2 clock cycles

The design isn't super optimized and can probably be speed up quiet a bit. However, if you experience the AI as to weak, there are better ways to improve it, than bare speed, e.g. opening tables.
