I just started using caravel flow in openlane, by running user_proj_example I am getting this error. Can anybody help

Not sure I can help you but I guess you have to show the entire error, maybe at the beginning of it is the key information

Can you show me the entire error? You are sure Have you completed $make setup, installed openlane and exported OPENLANE_ROOT, PDK_ROOT, PDK variables before running user_proj_example?

you shouldn't need to export OPENLANE_ROOT, PDK_ROOT & PDK variables i know the docs say to do that, but i think they're out of date and its all handled by the make file now

PDK_ROOT and OPENLANE_ROOT i exported, setup and all is done

can you clear PDK_ROOT and OPENLANE_ROOT?

It is error

oh strange, im not sure what the fix for that is, sorry

@Kristaps Jurkans I think it is necessary to set environment variables before running (OPENLANE_ROOT, PDK_ROOT, PDK). Tool does not support this update. So you have to update it manually. Otherwise it will fail and require manual updating

if you look in here https://github.com/efabless/caravel_user_project/blob/main/Makefile lines 18-39, the variables are set by the makefile itself on my machine, i do not have the environment variables set yet i'm able to run

make user_proj_example

with no issue:

kris@kris-desktop:~/repos/diy-ic/lincoln-gfmpw-1d$ echo $PDK

kris@kris-desktop:~/repos/diy-ic/lincoln-gfmpw-1d$ echo $PDK_ROOT

kris@kris-desktop:~/repos/diy-ic/lincoln-gfmpw-1d$ echo $OPENLANE_ROOT

kris@kris-desktop:~/repos/diy-ic/lincoln-gfmpw-1d$

Yes. If you place folders according to the above rules, it absolutely happens.

I have attached the file as well as error log
