You will design an electronic game of air$-$hockey that takes two players to play and implement it on FPGA device. You will be asked to demonstrate your implementation on FPGA device.$$The playground is $2-$dimensional $5$x$5$ area. You will use LEDs $($i$.$e$.$ LD$9$ to LD$5$ from right to left and left to right$)$ and a seven segment display $($SSD$4)$ to simulate the moving puck in X and Y axis, respectively, on FPGA. A puck moving from right to left is simulated as LEDs illuminating one after another starting with LD$9($i$.$e$.$ LD$9$ illuminates the leftmost column, then LD$8,$ LD$7,$ etc. It is basically a moving light$).$ SSD$5$ will display the Y$-$coordinate of the puck in decimal form.$$Assume that we have two players: A standing on the left hand side and B on the right hand side. The players will act using left and right buttons $($BTNL and BTNR$).$ Before the players start playing, a player will take the first turn using his$/$her button. Then, the initial score will be shown in the corresponding SSDs $($SSD$2-$SSD$0)$ as $0-0$ for $1$ second. Then, the score will disappear. Assume that, player A takes the first turn. After the initial score was displayed, LD$15$ will turn on to show an input is waited from the player A$.$ Player A will give the Y$-$coordinate and the direction which s$/$he wants to send the puck using his$/$her sliding switches $($SW$15-$SW$13$ for Y$-$coordinate and SW$12-$SW$11$ for the direction$).$ Then, s$/$he will press his$/$her button to send the puck and the puck will start moving. At the same time, LD$15$ will turn off $($because no input is waited from player A$).$ The speed of the puck will be $1$ second$/$step$.$ After $4$ seconds, the puck will arrive to the right$-$most column. When, the puck arrives the right$-$most column, player B must hit the puck. In order to inform player B$,$ when an input is expected from him$/$her$,$ LD$0$ will turn on$.$ When $($or before$)$ the puck arrives to the right$-$most column, player B must adjust the his$/$her SWs $($SW$2-$SW$0$ for Y$-$coordinate and SW$4-$SW$4$ for the direction according to the Y$-$coordinate of the puck and the direction that s$/$he wants to send the puck. Then, s$/$he must push his$/$her button to hit the puck and the puck will start going from right to left. When, s$/$he hits the puck, LD$0$ will turn off. Then, the same procedure will be done by player A$.$ And so on$.$When a player cannot hit the puck in a second $($either s$/$he does not press his$/$her button or Y$-$coordinate is invalid$),$ the other player will win the turn. In this case, the current score will be displayed and LD$9-$LD$5$ will turn on for a second. Then, the player who lost the previous turn, will start the next turn.
