How can I start the openroad gui for analyzing congestions from a Caravel User Project?

In

OPENLANE_ROOT

, change the follow variable in the

Makefile

ENV_START = docker run --rm\
        -v $(OPENLANE_DIR):/openlane\
        -v $(OPENLANE_DIR)/designs:/openlane/install\
        $(PDK_OPTS)\
        $(STD_CELL_OPTS)\
        $(DOCKER_OPTIONS)

to

ENV_START = docker run --rm\
        -v $(OPENLANE_DIR):/openlane\
        -v $(OPENLANE_DIR)/designs:/openlane/install\
        -v $(UPRJ_ROOT):/openlane/user_project\
        $(PDK_OPTS)\
        $(STD_CELL_OPTS)\
        $(DOCKER_OPTIONS)

(add the

UPRJ_ROOT

mount point).

export UPRJ_ROOT=<your caravel_user_project directory>
cd $OPENLANE_ROOT
make mount
openroad -gui

https://github.com/efabless/caravel_user_project/pull/273 <-- I am trying to add it as a Makefile target so that you can do "make gui"

@Mitch Bailey: Would you be able to review Philipp's Makefile addition pull request? The simple addition of a target like that should be non-controversial, but if it doesn't get a signoff then it's never going to get merged.

@Philipp Gühring If you are using a new version of openlane this might be useful https://openlane.readthedocs.io/en/latest/reference/gui.html

@Kareem Farid That works if the design is accessible from the

OPENLANE_ROOT

. The problem @Philipp Gühring was experiencing was that his

caravel_user_project

was in a directory outside of

OPENLANE_ROOT

and thus not accessible in the docker with

make mount

. His change to the

caravel_user_project/Makefile

mounts the user project to a directory that docker can access.

New openlane mounts $HOME so it is likely accessible now.

Great!
