Pong with output to VGA display, written in VHDL for implementation on nexys a7 dev board (part no. xc7a100tcsg324-1), built in vivado 2023.2

1. Open git bash, consider $origin_dir as the root directory of the repo

source $origin_dir/scripts/build_project.tcl

1. Open Vivado 2023.2 GUI
2. Click Tools > Run Tcl Script...
3. Select $origin_dir/scripts/build_project.tcl

Controlling up/down movement of the left paddle with push buttons on the dev board, CPU right paddle just tracks ball vertical position

Logic for control/output of game elements is mostly in hdl/pong_game_logic.vhd

Note: visual distortion in top middle of screen is due to degrading monitor hardware, not errors in the VGA HDL sections

• Simulation with verilator and vivado sim/modelsim
• Try different methods of pseudo-randomizing the initial ball position/velocity
• Change ball velocity when hitting P1 or CPU paddle
• CPU difficulty modes
• Win/Loss record
• Visual/audio cues & effects

• Further comments on time sync done for some of the VGA related signals in top file
• Logic walkthrough/state diagrams for hdl/pong_game_logic
