#1
LTspice
4.1
(74)
"LTSpice is what most people use."
"Best free simulator is LTSpice. Learn it and get comfortable with it."
"LTSPICE is my go to."
"Best FREE are LTspice and MicroCap."
"Ltspice is free and is used even by companies that could afford much more expensive suites."
"Download LTspice, it is accurate and used widely in industry."
"Best that someone asking this question can afford is LTSPICE."
"LTSpice is my favorite. It's free and powerful."
"LTspice! It's also made by Analogue Devices and has a ton of support with many manufactorers supplying parameters of their products that you can load into the program for accurate simulations of specific brand transistors etc."
"LTSpice for more professional work."
#2
Falstad
3.8
(17)
"Falstad.com/circuit/ is free and pretty damn accurate. I use it all the time before building stuff."
"This website is free https://www.falstad.com/circuit/"
"This one is pretty good. Coded by a physics professor, web page links to all kinds of other cool Java visualizers."
"I love using falstad simulator you can even run it on your phone"
"For something more graphical, try using http://www.falstad.com/circuit/."
"LTSpice and Falstad are great."
"Falstad for small, quick and efficient use."
"Falstad simulator is pretty good for general behavioral simulations and works in real-time."
"For quick "does this work or not" kind of simulations, especially digital logic, I really like http://www.falstad.com/circuit/"

#3
Multisim
3.6
(17)
"Multisim or LTspice"
"The most convenient one is Multisim."
"Multisim of national instruments"
"MultiSim is really cool and I was sad when I graduated college and couldn't use it for free anymore..."
"National Instruments Multisim isn’t too bad price wise for a student license. Probably the best option if you aren’t a student would be one of the completely free pieces of software listed like KiCad or LTSpice."
"I use Multisim for quick circuit simulation."
"Multi sim, Autodesk eagle, easy eda."
"I like multisim for circuit testing. It is a nice graphical spice simulator."
"Multisim hits that middle ground between being great and easy to use and incredibly frustrating due to minor annoyances. The circuit simulation is top notch though, very intuitive, massive library of real parts."
"For more complicated stuff there's Multisim, Pspice, something made by Cadence that I don't know the name of, and something made by Altium."
#4
Micro-Cap
4.2
(12)
"MicroCap's UI is head and shoulders above LTSpice."

"My favorite by far is Micro-Cap. The student version is free and has a great interface and is really powerful."
"Maybe the domain moved, but here's where I downloaded it from: https://www.spectrum-soft.com/download/download.shtm"
"Micro-Cap was excellent, great UX and powerful features."
"I've downloaded microcap and played around a little bit. The GUI instantly felt much more natural than ltspice's."
"Https://en.wikipedia.org/wiki/Micro-Cap"
"Micro-cap was released for free some months ago, never used it but heard that it's pretty powerful."
"In school, I used MicroCap quite a bit for my analog courses."
#5
Proteus
3.8
(11)
"Proteus lets you load hex files right into the virtual PIC as if it were the real thing, and simulates all the signals going in and out of the pins as well as connected devices/components."
"I will try Proteus, it seems to have a lot of common components and it pretty known."
"Proteus is good for microcontroller"
"Proteus"
"Proteus did uC simulation. I'm usually an Altium sufferer, but its simulation suite is shit."
"Proteus is excellent, but it's very expensive."
"I used Proteus last semester, and it works most of the times."
