Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for modeling of circuit operation and is an invaluable analysis tool. Simulating a circuit-s behavior before actually building it can greatly improve design efficiency by making faulty designs known as such, and providing insight into the behavior of electronics circuit designs. In particular, for integrated circuits, the tooling is expensive, breadboards are impractical, and probing the behavior of internal signals is extremely difficult. Therefore, almost all IC design relies heavily on simulation. The most well known analog simulator is SPICE. Some electronics simulators integrate a schematic editor, a simulation engine, and on-screen waveforms, and make «what-if» scenarios easy and instant. They also typically contain extensive model and device libraries. These models typically include transistor and IC models, generic components such as resistors, capacitors, inductors and transformers, user defined models (such as controlled current and voltage sources, or models in Verilog A or VHDL-AMS). When choosing the certain software for schematic analysis, one have to take into account convenience, GUI, speed and also how well the software can predict physical reality.
