customasm VS logisim-evolution

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.

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

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).

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.

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

Thanks to hlorenzi, making an assembler is a bunch of work. https://github.com/hlorenzi/customasm

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 used https://github.com/hlorenzi/customasm along with info from https://www.reddit.com/r/beneater/comments/cori8t/custom_asm_compiler_definition/

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)
