NL5 Circuit Simulator

NL5 Circuit Simulator was originally designed for SMPS applications; however, it has proven itself to be an excellent simulation tool for almost any field of electronics. Its fast and robust algorithm, highly interactive interface, and ability to handle true "ideal" components make NL5 especially efficient during the concept design stage of a project.

idealCircuit is an analog circuit simulator working with true ideal components. It uses exactly the same unique and robust algorithm as NL5 Circuit Simulator. However, it is simplified as much as possible: very simple and intuitive interface, less components and models, no fancy and powerful features.
