Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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)

Defining assembly instructions has killed my love of this game ultra fast.
I'm using customasm to write code in Turing Complete.

also if you start writing programs for your own CPUs, use something like CustomASM so you don't have to write in machine code.

Vending Machine - FPGA
either way if you plan on doing more CPUs and similar in the future i highly recommend CustomASM.

My 8-bit cpu running at full speed
The source code was in Python. I was able to debug it using Arduino-based adapter and (by using some "magic") translate into machine code binary. Since then I've switched to CustomAsm for code compilation and have other means to debug (emulator and debugger tool).

A really good assembler/compiler
Even though technically not an emulators-related post, I'd like to share a tool I've recently learned came across and found to be really useful. It's called customasm and is open source. It can compile assembly of any kind as long as you feed it with (what's called) rules-definition. You can even write a higher level language profile (such as C, sort of) through it, the possibilities are countless, so to say.

Programming a breadboard computer via customasm
I've got the documentation in the wiki! https://github.com/hlorenzi/customasm/wiki/User-Guide

CUSTOMASM, using customasm is cool (made by hlorenzi). You write some code in assembly in a text editor, assemble, download to the breadboard computer and run it. Changing modifying or extending code goes superfast. Best programming tool sofar. Description of the code in the comment section.
Thanks to hlorenzi, making an assembler is a bunch of work. https://github.com/hlorenzi/customasm

Today I finished the RAM module for my 16-bit breadboard computer!
anyways, it might be a good idea to throw the entire project on Github once it's done. stuff like schematics, BOM, details about the function of the CPU, maybe an Assembler (CustomASM is pretty good), also maybe a simulator version in something like Digital or Logisim so that people can look at it, write programs, or rebuild it with different parts and such

I was wanting an assembler I can use with my breadboard CPU, but the only one that allowed custom ISAs is Windows only. So, I created my own assembler with Python for custom ISAs, and included a configuration file for the original instruction set of Ben Easter's SAP-1. Still a bit rough, but usable.
I used https://github.com/hlorenzi/customasm along with info from https://www.reddit.com/r/beneater/comments/cori8t/custom_asm_compiler_definition/
