Getting started¶

Documentation home · Next: Interface

Open RGate on your desktop, or launch it in your browser. The starting circuit is a full adder, with three switches and two output LEDs.

Run your first circuit¶

1. Press Space or click Play.
2. Click A, B, and Cin to change the inputs.
3. Watch the Sum and Cout LEDs. The Nets panel shows the signal values too.
4. Click ○ beside Sum or Cout to record a waveform.
5. Press Space to pause, then use F6 to step through the next change.
6. Click Stop to return to editing.

Open an example¶

Choose File → Open… and select a .rgate file. The example circuits include adders, counters, a shift register, a Verilog PWM dimmer, an LC-3 computer, and a VGA controller.

To use a linked example, download its .rgate file, then open it in RGate. In the browser, Open lets you select a file from your device.

Build a small circuit¶

1. Choose File → New circuit.
2. Search Components for Switch. Drag it onto the canvas.
3. Add a second switch, an AND gate, and an LED.
4. Press W. Click a switch output, then an AND input. Connect the second switch to the other input and the AND output to the LED.
5. Press V or Escape to return to selection.
6. Press Space and toggle the switches. The LED lights when both inputs are high.
7. Choose File → Save to keep your circuit.

Set component widths in Properties before connecting buses. Use selection and wire dragging to adjust the layout, and Arrange to align components.

Write a Verilog module¶

In the desktop app, choose Module → New Verilog module…. Start with the counter template, edit its source in the Edit tab, and run it with RGate. You can place the module in a schematic and connect switches, a clock, and LEDs. Follow the Verilog guide for a complete walkthrough.

Keep your work¶

On desktop, Save writes a .rgate document. In the browser, Save downloads one. RGate remembers your panel sizes, theme, and views, and offers recovery of unsaved edits when you reopen it. See files and recovery.
