Tic-tac-toe game design based on Xilinx FPGA

Abstract: This design accomplished Tic-Tac-Toe game on Xilinx Spartan-IIE FPGA platformin VHDL. Firstly, designing the circuits and wiring on experiment board. Secondly,designing the algorithm and programming it in Active-HDL. Thirdly, synthesizingit in Synplicity Synplify Pro and then implementing it in Xilinx ISE developingsuite. Finally download it onto FPGA to run it. This design allows two players to play Tic-Tac-Toe game on the experiment board.Pressing the key, the corresponding LED will be light up to represent thechessman. There are two LEDs indicate whose turn next is. If the grid one wantsto place chessman has been taken up, then LCD will alarm it and ask the playerto replace it. The first player who forms 3 chessmen in a row, column or diagonalwins, LCD will display it and the three LEDs in the winning line will blink. If nobody wins after filling the whole chessboard, then LCD displays draw.
