export PDK_ROOT=<pdk-installation-path>

In above command what is this path? like which path I can use here to make it work correctly

PDK_ROOT is a path which contains open_pdks, sky130A and skywater-pdk. If you're using OpenLane flow, path is OpenLane/pdks. Else create your own custom path and point to PDK_ROOT

If you're running

make pdk

then it can be wherever you want the pdk to be build (I set the path to be

/tmp/pdk

. If you've already built and are running another command then it should be the path to the built pdks

I'm running caravel flow example and I getting this error at make verify-io_ports comand @User @User Kindly guide where I'm doing misktake

check Makefile line:38

I'm following the instructions through caravel user project for sample project and I'm doing all steps but at this comand I'm getting error

if not set, do with

export CARAVEL_ROOT= <path to caravel dir>

I have set but still not working

You shouldn't need to run any of the commands as root but that's probably not the issue.

rm -rf $PDK_ROOT

and

make clean

to try to reset everything and then try

make pdk

again
