iCircuit 3D

iCircuit 3D trades the physical feel of an electronics workbench for a circuit you can assemble and simulate on screen. That makes it handy for exploring how a design behaves before building it, and for learning the relationship between components. By our assessment, its main strength is the quick link between changing a circuit and seeing the simulated result. The 3D presentation also gives the design a more spatial view than a flat schematic alone. It belongs closer to an interactive learning and prototyping tool than to professional engineering software or a substitute for physical testing. A simulation can show what a circuit predicts, while a real build still has to confirm how the components behave together.
