My student made some openlane scripts that may be helpful - https://github.com/tdene/adder_networks

Thanks @User for the reply, but still not working 😔. I think it has something to do with the docker image of OpenLane and my local docker's configuration.

okay.let us know if you need any help

I fixed in a not elegant way, by changed the EXPORT_DESIGN value that it is use by make test command to test the flow against one design.
