FightPGA

A simple 2-player fighting game written from scratch in Verilog (targeting Cyclone V/DE1-SoC).

Project Setup

First you need to import the project into Quartus using the qpf file in the quartus folder. The sof file for direct upload to a DE1-SoC is also available in that folder. For anyone wishing to remap the pins, the pin assignments for the DE1 top-level module are:

Signal	Location	Explanation	Relevant Input on Board
clk_out	PIN_A11	VGA DAC Clock output
display_en	PIN_F10	VGA DAC enable output
hsync	PIN_B11	VGA DAC hsync
vga_sync	PIN_C10	VGA DAC sync output
vsync	PIN_D11	VGA DAC vsync output
p1_inputs[0]	PIN_AG25	Player 1 walk forward input	GPIO bank 1 pin 9
p1_inputs[1]	PIN_AF25	Player 1 walk backward input	GPIO bank 1 pin 7
p1_inputs[2]	PIN_AC23	Player 1 grab input	GPIO bank 1 pin 5
p1_inputs[3]	PIN_AE23	Player 1 block input	GPIO bank 1 pin 3
p1_inputs[4]	PIN_AA21	Player 1 kick input	GPIO bank 1 pin 1
p2_inputs[0]	PIN_AC22	Player 2 walk forward input	GPIO bank 1 pin 35
p2_inputs[1]	PIN_AD21	Player 2 walk backward input	GPIO bank 1 pin 33
p2_inputs[2]	PIN_AG22	Player 2 grab input	GPIO bank 1 pin 29
p2_inputs[3]	PIN_AF23	Player 2 block input	GPIO bank 1 pin 31
p2_inputs[4]	PIN_AJ22	Player 2 kick input	GPIO bank 1 pin 27
palette_select[0]	PIN_AB12	Palette swap bit 0 input	Slide switch 0
palette_select[1]	PIN_AC12	Palette swap bit 1 input	Slide switch 1
pll_locked	PIN_V16	PLL lock success LED output	LED 0
ref_clk	PIN_AF14	50 MHz onboard clock input
reset	PIN_AA14	Global reset input	Keybutton 0
vga_b[0]	PIN_B13	VGA DAC blue bit 0 output
vga_b[1]	PIN_G13	VGA DAC blue bit 1 output
vga_b[2]	PIN_H13	VGA DAC blue bit 2 output
vga_b[3]	PIN_F14	VGA DAC blue bit 3 output
vga_b[4]	PIN_H14	VGA DAC blue bit 4 output
vga_b[5]	PIN_F15	VGA DAC blue bit 5 output
vga_b[6]	PIN_G15	VGA DAC blue bit 6 output
vga_b[7]	PIN_J14	VGA DAC blue bit 7 output
vga_g[0]	PIN_J9	VGA DAC green bit 0 output
vga_g[1]	PIN_J10	VGA DAC green bit 1 output
vga_g[2]	PIN_H12	VGA DAC green bit 2 output
vga_g[3]	PIN_G10	VGA DAC green bit 3 output
vga_g[4]	PIN_G11	VGA DAC green bit 4 output
vga_g[5]	PIN_G12	VGA DAC green bit 5 output
vga_g[6]	PIN_F11	VGA DAC green bit 6 output
vga_g[7]	PIN_E11	VGA DAC green bit 7 output
vga_r[0]	PIN_A13	VGA DAC red bit 0 output
vga_r[1]	PIN_C13	VGA DAC red bit 1 output
vga_r[2]	PIN_E13	VGA DAC red bit 2 output
vga_r[3]	PIN_B12	VGA DAC red bit 3 output
vga_r[4]	PIN_C12	VGA DAC red bit 4 output
vga_r[5]	PIN_D12	VGA DAC red bit 5 output
vga_r[6]	PIN_E12	VGA DAC red bit 6 output
vga_r[7]	PIN_F13	VGA DAC red bit 7 output

If you are planning to remap the input buttons or use the controller on a different board, you will need to keep in mind where the pins for the inputs are located. The GPIO bank pin numbers are given assuming the notch on the header is on the left side, and pins are numbered left to right, top to bottom (pin 0 is at the top left) like so:

0	1
2	3
4	5
6	7
8	9
5V	GND
...	...

This is on the DE1-SoC.
