wd65c02 reviews and mentions

• Beginner Verilog Testing Question
  1 project | /r/FPGA | 13 Feb 2022

  I'm implementing a 6502. I wrote a test-bench program in Verilog that takes a mem file for the test program, and another for the test-plan, and verifies the CPU's execution against the test plan. You can check it out. Feel free to steal ideas. You can even use the code itself, so long as you honor the GPL it's under. Here is a link to the actual file inside the project.

• Building Ben's 8-bit CPU in VHDL (to learn a bit about FPGAs). Baby Step 1: Clock Module...
  2 projects | /r/beneater | 15 Nov 2021

  I started such a project in VeriLog once, if you want a reference. I abandoned it before getting to branches, however, in favor of writing a 6502 implementation.

• Stages of prototyping a RISC-V processor on an FPGA?
  3 projects | /r/FPGA | 21 Oct 2021

  You can look for ideas at my test bench. The testbench is available here. Don't copy any actual code unless you are willing to abide by the GPL, though. I doubt it will help you in the literal way, anyways, as it is built for testing a CISC CPU, so some adaptations will be required no matter how free you are to use the code. I am hoping it will give you some ideas.

• Debugging a timing loop
  1 project | /r/FPGA | 3 Oct 2021

  I have a design (available here) that has loops in the timing report after implementation. The problem is that I cannot seem to trace the nets I'm seeing in the report to my code, and those I did manage to trace seem to be routed through non-blocking assignments. I'm missing something, but I'm not sure what.

• Help with timing constraints

  The project source is here.

• Which is better?
  2 projects | /r/FPGA | 22 Sep 2021

  So I went through all the files in the wd65c02/wd65c02.srcs/sources_1/new/ directory, but I can't find the code snippets that you're talking about?
