I'm a little stuck on this section of the caravel installation instructions

cd <project_name> # project_name is the name of your repo

mkdir dependencies

export OPENLANE_ROOT=$(pwd)/dependencies/openlane_src # you need to export this whenever you start a new shell

export PDK_ROOT=$(pwd)/dependencies/pdks # you need to export this whenever you start a new shell

# export the PDK variant depending on your shuttle, if you don't know leave it to the default

# for sky130 MPW shuttles....
export PDK=sky130A

# for the gf180 GFMPW shuttles...
export PDK=gf180mcuC



make setup

I tried to follow this but I don't have

volare

and the installation doesn't seem to be working for me.

In any event, as @Tim Edwards said since I have already installed the PDK I shouldn't need volare anyway but my understanding is that caravel's

make setup

also installs caravel lite and the management core so how to I do that without having to install

volare

? can I just...

export OPENLANE_ROOT=/home/tom/repos/edatools/Openlane
export PDK_ROOT=/home/tom/repos/edalibs/pdks/gf180mcu
export PDK=gf180mcuC

followed by make setup?

The

volare

script should live in

~/.local/bin

. If it's there, add that directory to your

PATH

variable

thanks, @Ioannis. Can I do this without volare though? I already have the PDK installed and would rather point to the same one I'm using to build mu custom cells

I have only ever used the caravel_user_project repo with volare, so I will defer to somebody who has actually tried what you want to do 🙂

make setup

executes the following targets:

install check-env install_mcw openlane pdk-with-volare setup-timing-scripts

You can try executing these in order, but skipping

pdk-with-volare

. Be warned that some of these targets delete existing directories before creating new ones. If you’ve modified anything, I suggest backups in totally different directories.

Thanks @Mitch Bailey I managed to work around the issue for now but I will note that in case I need to do that again
