Build a circuit in four moves
PlaceOpen the Library or a bottom-bar group, then click a chip to place it. Drag a chip directly onto the canvas for direct placement.
ConnectClick a pin to start or finish a compatible wire, or drag directly from one pin to another. Click empty canvas to add route points.
InspectSelect an object to open its Inspector. Double-click chips, wires, notes, and labels for their edit action.
SimulateClick input devices to toggle them, use BAKE or SPACE to evaluate the circuit, and CLEAR to return to its initial state.
