Phase 1
Introduction
Brick is a popular game that is found on many of the newer cell phones. The objective of the game is to clear all of the bricks without losing all of the player’s lives. The player’s score will increment on the seven segment display each time a brick is hit. The bricks are square and will be colored differently to be able to tell where each brick begins and ends. The paddle is placed at the bottom of the screen, and there is a wall that appears on all sides of the screen except for the bottom, which is where the paddle is. If the ball goes off the screen, a life is lost.
Concept
By the projects end, the VGA monitor will display the famous brick game. The Basys board will be used to display the lives that a player has left along with their current score. It will control all aspects of the game. The ps/2 keyboard will control the user's input, movement of the paddle.
Proposed Work
1. ps2core module – takes in the raw data from the ps/2 keyboard and converts it into an opcode.
2. ps2decode module – takes the value from the ps2core module and decodes it into a form that can be used by the other various modules.
3. ball_control module – this module is used to control the movement of the ball and how it interacts with the current game environment.
4. paddle_control module – controls the paddles movement
5. draw_vga module – displays the current game state
6. vga_sync module – controls vertical and horizontal synchronization
7. brick_control module – controls whether or not a brick has been hit
8. score module – keeps track of the score of the game and increments the score each time a brick is hit
9. binarytobcd module – converts a binary number into a binary coded decimal
10. segdecode module – this module is used to convert the binary number to display on the seven segment display
11. lives_left module – this module will used LEDs to display the amount of lives left, and the number will decrement each time a life is lost
Required Parts
- PS/2 keyboard
- VGA Monitor
- Basys Spartan 3E Development Board
Expected Deliverables
When the project is completed, the game board will be displayed on the screen. The ball will begin moving, and the player will be able to move the paddle left or right using the arrow keys on the keyboard. At the start of a round, the ball will move downward and make a 45 degree turn if it hits the paddle. When the ball hits the paddle any other time, it should turn at a 90 degree angle. Otherwise, the game will decrement a life and reset the board. If the ball hits a brick, the brick should disappear, and the ball should make a 90 degree turn. When all bricks are cleared, the game is over.

Phase 4
Analysis of Proposed Work
After completion of the project the following modules were not complete: lives_left module: it was used to inform the user the amount of lives they had left through the LEDs.
Instead of creating the lives lost module, we included the information in the score module instead.
Functionality added:
- Instead of our game displaying an abundance of bricks on the screen, like the traditional game of Brick, we decided to only have it display three bricks at a time. Each time that a brick is hit, a new brick is displayed in a random location. This was done to increase the difficulty of the game, because a player would not know where the next brick would be displayed.
- Decrementing the paddle length each time a brick was hit is another feature that was added to increase the difficulty of the game. The paddle will only decrement down to the size of the ball.
