I installed OpenLANE from https://github.com/The-OpenROAD-Project/OpenLane I cloned caravel user project from https://github.com/efabless/caravel_user_project I was reading the manual quickstart of caravel_user_project, it says: "#. Now that your git environment is setup, it's time to setup your local environment by running. .. code:: bash # make sure to change <directory_name> with the directory you created in step 2 # in this case it is caravel_tutorial export OPENLANE_ROOT=~/<directory_name>/openlane # you need to export this whenever you start a new shell export PDK_ROOT=~/<directory_name>/pdks # you need to export this whenever you start a new shell make setup * This command will setup your environment by installing the following: - caravel_lite (a lite version of caravel) - management core for simulation - openlane to harden your design - pdk" Because I installed openlane before, do I need to "make setup" again from caravel_user_project folder ? Thanks

Probably depends how old your openlane is

well probably the safest way will be just to follow the steps from caravel_user_project, as you said then I need to install caravel_lite and management core for simulation

Yep

Actually the latest YouTube video of M. Shalan "Getting Started with Open MPW and chipIgnite" there is a slide states that "you only need to clone one repo: efabless/caravel_user_project"
