You're absolutely right, the project fits in EPM570. However, it's 100% full. The Verilog project repository is available at: https://github.com/andkorzh/OLD-Verilog-MOS6502

Based on the Logisim model, a circuit model was created in Quartus. It is also available in Verilog.

I managed to successfully complete the Klaus Dormann test on my MOS6502 model in the Logisim environment. The test was started on 08.08.24 and was completed 12 days later. The previous attempt was unsuccessful and small bugs were found in the decimal correction scheme. And after they were fixed, the ...

You can see how the blocks move inside 6502.

Welcome, and I'm curious to see how quick it is at a tiny basic :mrgreen: - my 8080 model takes about five minutes to count from zero to ten...

Thanks Neil!
Logisim produces approximately 150-200 clock pulses per second on this scheme, you can roughly calculate the performance. :) But when ...

Thanks!

Hello everyone! :) I would like to present my version of the 6502 project in Logisim. It is different from what was previously published here @Org. I had a slightly different approach, first of all, I got rid of all the tristates inside the design, except for one that controls the output data flow ...
