^^^^^
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.
Admittedly I have fond memories of multisim but that was over a decade ago and it is exactly unchanged since then.
Soon enough, a license for multisim will be like a family heirloom that will be passed down across the generations.
