Simulate a Circuit Board for Real

iCircuit is a utility program designed to be an easy-to-use electronic circuit simulator. Whether you’re a student or an actual engineer, iCircuit can help you, as it actually simulates the behavior of a circuit board. No pausing in-between tests—this app simulates in real-time so you can get better results and measurements. iCircuit also acts as a circuit board designer, letting you fiddle with various elements like resistors, switches, MOSFETs, digital gates, and more. It even has a multimeter for instant voltage and current readings. However, don’t expect many advanced features in this program. It performs simple tasks well enough, but there are still issues that may annoy veteran users of such an app.
