RGate is a spiritual successor to TkGate: a place to build, explore, and understand digital circuits. Draw schematics, connect gates, and organize larger designs into reusable modules—or write Verilog modules and connect them to your circuits.
Run your designs, change inputs, and watch the results through LEDs, displays, and waveforms. Step through circuit behavior and look inside module instances to see how the pieces work together. Browse the user documentation.
Explore the example circuits, from simple adders to a VGA controller and an LC-3 computer. Open one, follow the signals, and make it your own.
