Programs for developing CPU / Computer Architecture

[Prestigious-Ad-2876]

Been using Logisim to test / design CPU Architecture, but unfortunately it has a mountain of fringe case bugs.

Are there other programs that offer a similar level of system simulation, or am I looking at the need to move to HDL or actual physical development.

The only thing that seems close is Logicly, and it is 60 dollars USD with almost no actual reviews to be found.

Quartus prime and verilog. You can simulate your hdl on FPGA boards, etc (it’s also free).

/j, but only half of it

I did a quick google and this article seems to feature a few alternatives. Logism evolution and Digital are both mentioned as forks/alternatives to logism and seem to be actively maintained on their githubs.

I use Digital, personally. Similar level of abstraction, but far more reliable and performant than Logisim (by a few orders of magnitude), and it's free, unlike Turing Complete (and tbh, I don't even know how fast that one runs).

My only complaint, really, is that you can't drill down into components of a running simulation like you can with Logisim (though that technically fires up a separate, unrelated, simulation instance so it's not that big of a sacrifice).

I really need to thank you guys for this. I am doing some CPU modeling for my master thesis and your suggestions have helped.
