Just a quick sanity check - which one of these two should I be using? • https://github.com/The-OpenROAD-Project/OpenLane • https://github.com/efabless/OpenLane

For the shuttles, you want to clone https://github.com/efabless/caravel_user_project.git or https://github.com/efabless/caravel_user_project_analog.git The versions of the pdk and openlane required are specified in the makefiles and should be made from the makefiles, I believe.
