Flappy Bird Game Console on Terasic DE2-115 FPGA Board

Project Overview

This project implements a Flappy Bird-style game on the Terasic DE2-115 FPGA development board. The game utilizes FPGA peripherals such as VGA for graphical rendering, onboard push buttons for user input, and a seven-segment display for score tracking. Designed using Verilog in Quartus Prime, the project showcases real-time systems, finite state machines (FSMs), and optimized resource usage.

Features

• VGA Display (640x480 resolution):
  • Bird: Pink block
  • Obstacles: Purple pillars with randomly placed holes
  • Background: Dark purple
• Game Mechanics:
  • Player controls the bird’s vertical position by pressing a button to make it flap.
  • Bird must navigate through gaps in the obstacles to score points.
  • Collisions with pillars or the screen boundaries result in game over.
  • Pause Feature: A toggle switch (Switch 17) pauses the game, turning the screen black and white.
• Input Control:
  • Push buttons handle the bird’s flapping motion.
  • Debounced signals ensure stable input.
• Score Tracking:
  • Scores are displayed on the seven-segment display in real-time.
  • High scores can be stored and retrieved.

System Design

The project follows a modular design:

1. Master Controller Module:
   • Manages game state transitions (start, play, pause, game over).
   • Handles initialization and resets.
2. Game Controller Module:
   • Implements bird movement, obstacle generation, collision detection, and score updates.
   • Uses a random number generator to determine the positions of gaps in obstacles.
3. Seven-Segment Display Controller Module:
   • Updates and displays the player’s current score and high score.
4. VGA Controller Module:
   • Generates VGA signals to render the game elements (bird, obstacles, and background).
   • Handles black-and-white rendering during the pause state.
5. Random Number Generator Module:
   • Creates random positions for the gaps in the obstacles to enhance gameplay.
