Yeah, I started on it and felt the same so I built https://git.sr.ht/~vhodges/cputhing There's * https://nandgame.com/ * https://github.com/logisim-evolution/logisim-evolution too

Logisim is a nice FOSS software in this space as well. I've designed a CPU in it during COVID, which then became a never-finished breadboard project that stilll looks at me accusingly from some corner of my living room. Oh well. In addition to boolean logic, Logisim also includes more advanced components such as static RAM, as well as interesting things to drive with it, such as displays. It was developed for use in schools and is therefore designed to be easy to work (or rather play) with. The project itself has been dead since 2011 or so, but there is an actively maintained fork [1]. [1]: https://github.com/logisim-evolution/logisim-evolution

Logism evolution works great and is quite modern. https://github.com/logisim-evolution/logisim-evolution

In school, I worked on an introductory CS/EE class many, many moons ago, and I believed we used something like "logisim", which by then was pretty awesome - you could build simple things like adders, combine those with "macros" to bui;d ALUs and then whole simple CPUs. Since then, the logisim project has discontinued, but it looks like there is a open source successor: https://github.com/logisim-evolution/logisim-evolution Have not tried it, but it looks promising, provided you don't want to do too complicated things (not sure if you could really model complex CPUs like a pentium with it). Also, it's pretty digital only, so I wouldn't expect Mac-Spice-like analog circuit simulation.

Very cool tool. Almost 2 decades ago, I learnt Principles of Digital Design in the university using EWB (Electronics Workbench), then known as Multisim. It's Windows only. Then a friend pointed me to Logisim, which also runs well on Linux. Unfortunately, the development was suspended, which lead to various forks like: - https://github.com/lbulej/fork-logisim-evolution - https://github.com/Logisim-Ita/Logisim - https://github.com/logisim-evolution/logisim-evolution

Looks like development was suspended back in 2014. There seems to be a recently maintained fork: https://github.com/logisim-evolution/logisim-evolution
