Abstract

CodeGolf is a mini-golf game through an FPGA board. The game takes directional input from the Nexys DDR4 board and hit-power input from the PMOD NumPad to allow the user to play mini-golf.

Project Workflow

1. Brainstorm ideas and select a project (DONE)

2. Develop abstract, project deliverable, and materials (DONE)

3. Develop finite state machine / logic (DONE)

4. Write VHDL code (DONE)

5. Synthesize (DONE)

6. Implement (DONE)

7. Generate bit stream (DONE)

8. Program board (DONE)

9. If time permits, make more levels & implement potentiometer (NOT IMPLEMENTED)

Project Materials

• Nexys DDR4 Board

• PMOD NumpPad

• VGA Monitor

Finite State Machine (FSM) Model

VHDL Code

Goals of Code:

• Ball's direction is determined by directional buttons on FPGA

• Ball's power level is determined by potentiometer

• Design walls and "hole" for each level/course

• Create logic for wall bounces / Game Over Case

  • Game over screen / Restart

• Total stroke counter

  • Use seven-segment display for strokes

Future Ideas

• Pinball

• Additional courses

• Max stroke count
