9 months ago Congratulations on getting posted on Hackaday today!
Have updated the by_name and by_author PDFs to https://github.com/jimbrake/cpu_soft_cores Your two designs are at bit_serial and forth-cpu Andrew Holme's designs are at mark-1, mark-2 and chip_6502
Downloaded your latest bit-serial design. Your bit_serial design ran fine under ISE 14.7 into Spartan-6 PDF shows several runs. Did not match your LUT numbers. Prefer the Project Archive ZIP file as best documentation of runs.

This is a great list!
Just a minor correction and a question.
On line 273 I'm listed as the author of https://anycpu.org/forum/viewtopic.php?f=13&t=333, "Richard Howe", which I'm not, I'm author of "H2" https://github.com/howerj/forth-cpu and the "bit-serial" CPU https://github.com/howerj/bit-serial (which you've already entered). I believe an "Andrew Holme" is an author of that (very impressive) project.
I've also noticed that you couldn't get the bit-serial project to work, it failing with a BRAM error, it might be because you have an incorrect size for the image/BRAM size ("max dat"/"max inst" show as 4K, the Forth image was bigger than this (newer images are smaller than 4KiB), and the BRAM is 8192 16-bit values in size on the Spartan-6 it runs on).
Thanks, Richard James Howe
