^^^^^
The above worthless trash known as “multisim”, used for simulating circuits costs 905 EUR and
- Doesn’t have a linux version
- Is missing 90% of new commercially available parts
- Doesn’t have a method of easily adding those parts (except manually, 1 by 1) (as far as I know)
- Has garbage UI (you can only undo 4 times) (adding or removing a single component can easily use up more than 4 moves)
- Inconsistent simulations (making the sims work feels like trying to appease a capricious God to not curse you with famine)
The free open source software (qucs-studio) seems to have none of these problems, though I have barely used it.
They make a ton of specialized industrial and electronics shit and a ton of niche professional software and are extremely money hungry. Most of their products have the same experience as this one.
