Astro8-Computer VS logisim-evolution

I Designed My Own 16-bit CPU AstroSam, 16 years old, designed a 16-bit CPU called Astro-8, created an assembly language for it and finally created a compiled language named Armstrong (deal with it). All the video is entertaining and the work is impressive when you take into account Sam's age. All the code and schemas are on GitHub. I also discovered Logisim-evolution tool watching the video.

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.

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:

Logism evolution works great and is quite modern.

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.

Did you check logisim-evolution? It is an active fork of logisim maintained by several lecturers at the Bern University of Applied Sciences.

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:

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.

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)

Logisim-evolution An alternative free and open-source tool to design and simulate digital logic.
