This project is a hardware implementation of the classic Snake game, crafted in SystemVerilog for the DE1-SoC FPGA board. It integrates a VGA display for output and a PS2 keyboard for input, delivering a retro gaming experience with modern hardware design techniques. Through efficient use of finite state machines, a pseudo-random number generator for dynamic gameplay, and on-chip RAM for state management, the game aims to provide an engaging and smooth user experience.
- Dynamic VGA Display: Achieved through single buffering for seamless visual output.
- Real-time PS2 Keyboard Input: For intuitive and responsive control of the snake.
- Efficient Game Logic Management: Utilizing two finite state machines for a streamlined gameplay experience.
- Pseudo-random Number Generator: To randomize game elements, enhancing the challenge.
- On-Chip RAM Storage: For quick retrieval and storage of game states and images, ensuring continuity and a smooth user experience.
- snake_game.sv: The main game module that integrates all components.
- snake.sv: Manages the snake's logic, including movement and growth.
- rate_divider.v, memory_counter.v, keyboard_input.v, hex_decoder.v, counter.v: Supporting modules for timing, memory management, input processing, and display logic.
- vga.sv: A stub for the VGA output logic, illustrating the required interface.
- DE1-SoC FPGA Board
- VGA-compatible monitor
- PS/2 Keyboard
- Hardware Setup: Connect your VGA monitor and PS/2 keyboard to the FPGA board.
- VGA and PS2 Adapters: Locate and integrate compatible VGA and PS2 adapters. These can be found through online repositories or FPGA communities.
- Compilation and Programming: Compile the project in your FPGA development environment and upload it to the DE1-SoC board following standard procedures.
Navigate the snake to consume food, grow in length, and avoid collisions. The game leverages keyboard inputs for direction control and employs a scoring system based on food consumption.
