Tic Tac Toe is a popular game that is played on a 3x3 grid, with two players taking turns marking spaces with X or O. Implementing this game on an FPGA using a Hardware Description Language (HDL) such as Verilog or VHDL can provide a fun and challenging exercise in digital design.
To implement Tic Tac Toe on an FPGA, the first step is to define the input and output interfaces of the game. The game will need to receive input from the players, which can be done through buttons or switches connected to the FPGA board. The output will be displayed on a display connected to the board, which can be an LED matrix or an LCD screen.
Next, the game logic needs to be defined using HDL. The game logic will need to keep track of the state of the game, including which spaces are occupied by X or O, and whose turn it is to play. The logic should also check for winning conditions, which include having three of the same symbol in a row, column, or diagonal.
Finally, the game needs to be tested and debugged to ensure that it functions correctly. This may involve simulating the game in software, or using debugging tools provided by the FPGA development environment.
