Let me ask (maybe) very principle question… I finished “Quick start for caravel_user_project” flow, and next I tried to code my circuit in user_proj_example.v. With setting environmental variables of OPENLANE_ROOT and PDK_ROOT, I tried “make user_proj_example” in step 5., and faced the following error from docker. ------------ docker: Error response from daemon: Duplicate mount point: /home/akita/MPW6/caravel_tutorial/MPW6_mychip. ------------ Any advise to solve it, or correct flow to implement my circuit?

Sounds like two of your environment variables are the same. The Makefile uses the following mount points for docker (relative to

caravel_example/openlane

-v $(PDK_ROOT):$(PDK_ROOT) \
                -v $(PWD)/..:$(PWD)/.. \
                -v $(MCW_ROOT):$(MCW_ROOT) \
                -v $(CARAVEL_ROOT):$(CARAVEL_ROOT) \

Each of these environment variables should be a different directory.

CARAVEL_ROOT

defaults to

<caravel_example>/caravel

MCW_ROOT

defaults to

<caravel_example>/mcw_core_wrapper

The instructions in quick start can be a little confusing. Your directory structure should be something like

caravel_tutorial
| openlane
| pdks
| caravel_example
