I implemented risc-v in logisim. Here it is running a Fibonacci program written in C
You can see my Makefile here: https://github.com/mortie/rv32i-logisim-cpu/blob/main/Makefile

Problem with installation
I have downloaded logisim-evolution from github. While trying to run .msi file, Microsoft Defender blocked it for some reason. I scanned it with some other scanners and everything was fine. I'm not sure if this is safe to install it.

Creating a package that requires Java 16
I am trying to define an xbps-src template for logisim-evolution, a Java app that requires Java 16. I am using depends="virtual?java-runtime" and, as expected by reading etc/defaults.virtual, OpenJDK 8 is used. Creating a etc/virtual file is ignored in .gitignore, so I guess it is made to be used with local packages. Using depends="virtual?java-runtime-17.0.5+7_1" works, as OpenJDK 17 provides that exact version of java-runtime. If it were updated, this package would break, because if I input a lower version, it will fail. I've tried using syntax like > and >=, but then I get the following error:

A circuit simulator that doesn't look like it was made in 2003
Logism evolution works great and is quite modern.

Hi there, I got an assigment that consists of moving a stepper motor (4 phases) using only a 74LS76N and a 74LS86N but when I tried to use the schematic, it didn't work, any help would be extremely helpful (more info in comments)
According to Logisim it creates the correct sequence for full stepping on a bipolar configuration. Falstad's Circuit simulator is another one you might try.

Help needed to find FOSS tools to create graphical logic circuits and convert them to VHDL in class.
Did you check logisim-evolution? It is an active fork of logisim maintained by several lecturers at the Bern University of Applied Sciences.

Crumb Circuit Simulator
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.

I was making adder circuits in games 8 years ago in an attempt to build a computer. I finally worked my way up and built a working computer!
though i'd heavily recommend first building the circuit in a logic simulator like Logisim, or Digital before trying to build it in a game for an FPGA. (Digital even allows you to export circuits as Verilog/VHDL, and as a certified lazy person, that is very useful)
