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 &lt;directory_name&gt; with the directory you created in step 2
	# in this case it is caravel_tutorial
	export OPENLANE_ROOT=~/&lt;directory_name&gt;/openlane # you need to export this whenever you start a new shell
	
	export PDK_ROOT=~/&lt;directory_name&gt;/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

Check the makefile to see the setup target

I think youll need 2, install caravel and the mgmt core

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

when you first try to get your hands dirty and search for openlane, you first find openroad repo, but actually for mpw you don't need that repo as caravel_user_project makefile will install openlane and pdk, that's sth that I figured out actually

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"
