List of free electronics circuit simulators

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.

Some of the following simulators don't include a graphical visual interface, so a separate program must be chosen to provide that feature, such as Qucs-S,[1] Oregano,[2] or a PCB suite that supports external simulators, such as KiCad or gEDA.
