When talking about open source tools, here are some: KiCad may be used as a schematic entry tool for ngspice, especially for discrete or PCB-based electronics. You may watch several simulation examples (including oscillators) here: https://forum.kicad.info/t/simulation-examples-for-kicad-eeschema-ngspice/34443. KiCad integrates ngspice internally, but may also provide external ngspice with netlists for simulation.... - Source: Hacker News / 9 months ago
Https://ra3xdh.github.io It's only missing a solid components library like LTSpice has. - Source: Hacker News / 9 months ago
You should consider using qucs-s https://ra3xdh.github.io/ a fully open-source fork of qucs still currently maintained and improved. - Source: Hacker News / 9 months ago

Https://ra3xdh.github.io It's still missing a comprehensive component library like LTspice does, though. KiCad can also simulate circuits through NGSpice, but it's missing a library and suffers from a lot of quirks. - Source: Hacker News / over 1 year ago
On the other hand, SPICE started as a way to simulate the circuit effectively as accurately as possible. Modern SPICE methods support incredibly detailed models of components, and are designed to be able to simulate circuits literal hundreds of thousands to even millions of circuit elements at once. I have a simulation for work with 997 elements running in the background, and that's considered low for high-end... Source: over 1 year ago
(Feed the troll? Why not--it's Saturday and I'm a bit bored...) Now a useful comment might include some notes like these... Designing switched mode supplies is hard. I've just barely started playing with them, but it's really tough choosing component values that don't ring like a bell, a loud bell, at pretty high frequencies. I've found these two series of web pages [0] [1] to be very useful, even... - Source: Hacker News / about 2 years ago
Pspice - OrCAD PSpice technology provides the best, high-performance circuit simulation to analyze and refine your circuits, components, and parameters before committing to layout and fabrication
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.
