From Wikipedia, the free encyclopedia

List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S,[1] Oregano,[2] or a schematic design application that supports external simulators, such as KiCad or gEDA.
