I see openroad tool need unpaded lef. I am just added only user_project_wrapper.merged_unpadded.lef.gz in the lef directory
you can unzip and use this lef
user_project_wrapper.merged_unpadded.lef.gz
You can use below command to open in openroad
read_lef user_project_wrapper.merged_unpadded.lef
read_def ../def/user_project_wrapper.def
from riscduino.

This works for me .. Not sure issue related to openroad tool version difference .. I have standalone installed openroad application
from riscduino.

Thank you very very much!
I have solved the problem on my side, one last question, how to generate the unpaded lef file? .merged_unpadded.lef
from riscduino.

merged_unpadded.lef are generated when you run openlane flow. For user_project_wrapper , I see them generated at "openlane/user_project_wrapper/runs/user_project_wrapper/tmp/merged_unpadded.lef"
from riscduino.
