There are tons of free options out there for circuit simulation. We would love to learn which ones you've used.
For personal projects, most of us simply can't afford the fancy circuit simulation software packages we may access at work. Of course, that doesn't mean we're not going to use simulation software at all. We'll just use free software.
However, many of us don't know where to start. There are so many packages out there that we don't know which ones are the best fit. Even worse, maybe there are ones we haven't even heard of yet. Help us collect a list, so that we can document and compare them to help you find out if there is free software that would be a a good fit for your job.
To clarify, we aren't looking at any other kind of free software right now. Free CAD and PCB design software would be fun, but we'll have to save that for the next round. Right now, we're only asking about circuit simulation. This can be a program to be downloaded, an app, or a web-based tool. We aren't picky.
Since there are so many, we intend to break them up by signal type. There are three main categories: analog, digital, and mixed signal. Here's the list we have so far.
- Cool Spice
- Electric VLSI
- Tina TI
- Chipmunk Diglog
- DC AC Lab
- Gecko Circuits
- Micro Cap
Many of you might be curious about what some of these tools are and do, but you'll just have to be patient. We will detail each one soon. We just want to make sure we don't miss any important ones.
Please let us know in the comments if you've used any of these, or if we missed any. We would love to know why you chose what you've used, what you like about them, or why you moved to something else.
