LTspice® is a powerful, fast, and free SPICE simulator software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. Its graphical schematic capture interface allows you to probe schematics and produce simulation results, which can be explored further through the built-in waveform viewer.

Get Up and Running with LTspice
The key to most circuit designs is the speed with which you can reach an understanding of your circuit, its correctness, and its limitations. LTspice outperforms many other simulation tools and enables you to iterate your designs in minimal time.
