iCircuit Electronics Simulator

iCircuit Electronics Simulator is a hands-on circuit design and learning tool that lets you build, test, and explore analog and digital electronics in real time. The app’s always-on simulation engine keeps the virtual circuit powered as you edit, so measurements feel immediate and intuitive without pausing for separate analyses. It includes built-in instruments such as a multimeter and an oscilloscope and a component library suitable for classroom and hobby projects, making it useful for students, hobbyists and engineers prototyping ideas, demonstrating concepts, or iterating on designs.

Key Features

Realtime always-on simulation engine that updates as you add or change components, providing immediate feedback during edits.

Support for both analog and digital elements, including resistors, capacitors, inductors, diodes, BJTs and MOSFETs.

Over 30 component types, plus signal generators, voltage and current sources and dependent sources for common educational and hobby circuits.

Integrated multimeter for probing voltages and currents instantly within the circuit and a built-in oscilloscope that can track multiple signals with touch controls, adjustable time base, and stacked or unstacked display modes.

Advantages

iCircuit Electronics Simulator is an effective educational tool that bridges schematic editing and hands-on experimentation for learning and demonstration.

The live simulation behavior makes troubleshooting and testing feel natural and immediate compared with stop-and-run workflows.

A friendly CAD-style interface makes it straightforward to add elements, connect nets, and set component properties, including a range of digital parts such as logic gates, flip-flops, 7400-series components and a 7-segment driver for mixed-signal projects.

Disadvantages

Not intended as a full replacement for high-end industry-grade simulation suites with extensive specialized device models.

The component set is focused on practical learning and hobby use, which may be limiting for very specialized professional workflows.

Users coming from traditional stop-and-run analysis tools may need time to adjust to the always-on interactive workflow.

iCircuit Electronics Simulator is designed to support learning, quick prototyping and classroom use while remaining approachable for hobbyists and educators.
