★ Virtual Basys 3 · runs in your browser

The FPGA Arcade

A whole Digilent Basys 3 board, simulated on your own computer. Load real Verilog, VHDL and SystemVerilog designs and play them with your keyboard, mouse or game pad. No board, no cables, no install.

No board needed

The switches, buttons, LEDs, 7-segment display and VGA screen of a Basys 3 all run in the browser tab.

Play with what you have

Arrow keys, WASD, mouse, SNES and NES pads or a USB controller. Board buttons map to your keyboard.

Real sensors, simulated

Distance, tilt, force, IR remotes, RFID, keypads, joysticks and displays, each with an on-screen control.

Three HDLs

Verilog, SystemVerilog and VHDL designs, the same code you would put on a real board.

Read the source

Every game links to its GitHub code, so you can see exactly how it was built and borrow ideas.

Made for learning

Ideal for labs and course projects: test a design at home, then load it on the board in class.

How it works

Pick a game below, or press Launch to open the empty board.
Read the controls on its card: which keys, switches or sensors it uses.
Play. Flip the switches, press the buttons, and watch the LEDs and screen react just like the real board.
