Hello All, I am looking at attempting to rebuild this https://github.com/efabless/clear clear FPGA on the latest shuttle and caravel project wrapper, by chance does anyone have tips for porting older designs like this (MPW 9C) to the latest? Ive also noticed that this shuttle was before config.json became the standard, I see some of the configuration variables are missing between the two, any advice on fixing those differences would be helpful as well.
