Live circuit.
Search a part, wire the pins, type a value, press Live. Then close the switch and watch the capacitor charge, in real time.
Read the transcript
- Search a part, click to drop it in.
- Add a switch, resistor and capacitor.
- Press W, then click pin to pin.
- Type values the way you say them: 470u.
- Hit Live: it simulates while you watch.
- Press P, click a wire to put it on the scope.
- Click the switch and watch it charge.
The circuit is a 5 V source, a switch, a 1 kΩ resistor and a 470 µF capacitor (τ ≈ 0.47 s). After the switch closes, the oscilloscope shows the capacitor voltage rising toward 5 V while current dots move through the wires.

01 / THE WORKFLOW
Less friction.
More understanding.
From the first connection to the last measurement. Stay close to your circuit, every step of the way.

Follow the signal.
Probe a wire. Compare traces. Read voltage, current and power in the context of your circuit.
02 / INSIDE THE SIGNAL
Don’t just see a result.
Understand the behavior.
Three ways to ask “why?”
Explore real results from the desktop solver.
SIGNALS OVER TIME
One signal in. A new perspective out.
A 500 Hz sine passes through an RC low-pass filter. The output is smaller, and arrives later. Select a node to follow its trace.

Narrated tutorial + build videosCapacitive DC-DC converters: how a charge pump works.
See how a charge pump doubles or inverts a voltage with switches and capacitors, why its output sags under load, and simulate both circuits in Simvolta.
GETTING STARTED · 6 MIN READ
Your first circuit: predict, run, understand.
Build a voltage divider, predict its voltage and current, then discover why adding a load changes the answer.
SIGNALS & INTUITION · 7 MIN READ
Read an RC filter in time and frequency.
Connect a 500 Hz transient to a 159 Hz Bode corner, and learn why startup, phase and small-signal analysis tell different parts of the story.
BETTER EXPERIMENTS · 6 MIN READ
A component symbol is not the whole component.
Understand generic devices, supported SPICE models and the limits of numerical accuracy before turning a simulated circuit into a physical one.
SIMULATION BASICS · 7 MIN READ
DC, AC or transient? Choose the analysis that answers your question.
Three analyses, three questions. Real results from a divider, an RC filter and a rectifier show when to use a DC operating point, a transient run or an AC sweep.
SIMVOLTA AT A GLANCE
What it is.
Where it stands.
The short answers, before you decide whether Simvolta is worth a place on your desk.
- What is Simvolta?
- A desktop application for drawing electronic circuits and simulating them. You build a schematic on a canvas, run an analysis, and read voltage, current and waveforms in the context of the circuit itself.
- Who is it for?
- Students learning circuit fundamentals, hobbyists checking an idea before the breadboard, and anyone teaching or explaining how a circuit behaves.
- Which analyses does it run?
- DC operating point, transient (waveforms over time) and AC small-signal frequency response with Bode plots. When to use each analysis.
- How does Live simulation work?
- Live runs the circuit continuously. Operate switches, push buttons and PWM duty while it runs, and watch wire colors, moving current dots and the oscilloscope respond without restarting.
- What can I build?
- Resistors, capacitors, inductors, transformers, DC, pulse, sine and PWM sources, diodes, BJTs, MOSFETs, op-amps, comparators, a 555 timer and controlled sources, plus your own components. Start with the circuit examples.
- How are projects stored?
- As versioned files on your computer, with local recovery backups; the simulator works offline. Documented subsets of SPICE netlists, KiCad schematics and Falstad/CircuitJS circuits can be imported and exported. Interchange details.
- Can I download it today?
- Not yet. Simvolta is in development and no public installer has been released. macOS Apple Silicon development builds are tested; Windows release validation is in progress. Release status.
- Why get a release notification?
- One email when a verified release is available for download. No newsletter. The privacy page explains how the address is handled.
