An analogue SPICE circuit simulator distributed free by a component manufacturer. It is known for its execution speed and for accurate switching converter models, which makes it the standard tool for checking power supplies, filters and amplifier circuits before building them. There is no limit on node or component count, which sets it apart from the demo editions of commercial simulators. The interface is dated, but the results are trusted and the community around it is large.
