iCircuit for Windows

Quick overview

iCircuit is a straightforward electronics simulator and circuit-layout tool aimed at learners and hobbyists, and it can also serve practical uses for engineers. It runs simulations continuously in real time, letting you observe circuit behavior and take measurements without stopping and restarting tests. The app combines a schematic editor and a simple toolkit for building and testing circuits.

Core capabilities

• Digital logic components such as AND/OR gates and other logic blocks
• MOSFETs and other transistor types for analog switching
• Interactive switches and other control elements
• Basic passive parts like resistors and capacitors
• An integrated multimeter for instant voltage and current readings

Limitations and considerations

iCircuit handles common, straightforward tasks reliably, but it isn’t targeted at power users. Expect a relatively modest feature set compared with professional-grade simulators, and some behaviors or missing tools may frustrate experienced users. If you need complex SPICE-level modeling, advanced waveform analysis, or extensive component libraries, this app is likely too limited.

Recommended paid alternative

Electronic Toolbox (commercial) — a more feature-rich paid option that offers expanded component libraries and additional analysis tools for users who need capabilities beyond what simpler simulators provide.
