QUCS
Qucs, briefly for Quite Universal Circuit Simulator, is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit.
Some of the top features or benefits of QUCS are: Open Source, Comprehensive Simulation, Cross-Platform Compatibility, Wide Component Library, User Community Support, and Detailed Documentation. You can visit the info page to learn more.
