Hi I am new to OpenRAM and try to tun an example . i get the following errors:

Thanks.

Which version are you using? I suggest using the dev branch. It's best to follow these instructions which have been updated recently: https://github.com/VLSIDA/OpenRAM/blob/dev/docs/source/basic_usage.md In particular, the docker image is highly recommended.

Thanks, I will check the link, meanwhile ... How do I find the version? I installed by coping the git repo and run

make build

from docker folder.

git log will tell you at the top

I see v1.2.0 is this usefull?

You are using stable, not dev

OK, maybe stupid question : I need to reinstall cloning again the Git repo after setting to dev? or just running the

make build

after setting to dev?

Yes, you will likely need to reinstall again. You may need to do "make wipe" to remove the previous libraries. This will delete PDK_ROOT and other repos that it fetched. Be prepared to Ctrl-C if you don't like the paths that will be deleted
