Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for modeling of circuit operation and is an invaluable analysis tool.
This roundup only includes software with a graphical user interface. Circuit simulation backends are covered in this roundup. And software that offers electronic design automation are also covered in a separate roundup.
Here’s our verdict captured in a legendary LinuxLinks-style chart. Only free and open source software is eligible for inclusion.

Let’s explore the GUI circuit simulators at hand. For each program, we have compiled its own portal page, a full description with an in-depth analysis of its features, a screenshot of the software in action, together with links to relevant resources.
