Visualize

One animated circuit is worth a thousand equations and diagrams. Animations of voltages, currents, and charges are displayed right on top of schematic, providing great insight into circuit operation.

Simulate

Real-time circuit simulation engine is custom-built for speed and interactivity. Easy one-click simulation, from simple resistors and logic gates, to complex transistor-level oscillators and mixed-signal designs.

Interact

While simulation is running, you can flip switches, adjust potentiometers, tune LED current limiting resistors, ramp up input voltages, etc. The circuit will immediately respond to your changes, in real time.

Features powerful and beautiful

Circuits come alive with uninterrupted flow of simulation data.
Dynamic oscilloscope opens new angles for circuit analysis.

Analog and digital circuits

Mini-waveforms on top of schemaic wires look different for digital and analog signals. Constant analog voltages are shown as numbers, digital wires are color-coded.

I-V curve characteristics

Family of I-V curves for a MOSFET transistor are obtained by stepping the gate voltage. Notice how linear and saturation regions are visualized inside the MOSFET symbol.

AC analysis with Bode plot

Frequency response changes when circuit is modified. Phases and magnitudes are shown in schematic as circles. Notice them change as the frequency trace is moved.

Oscillator orbit evolution

Any pair of time-domain signals may be plotted in the XY mode. The oscilloscope scale and grid ticks are auto-updated to convenient values as the data changes.

Analog and digital components can be
simulated together in one circuit.
