Could anyone give some advice about caravel on IIC-OSIC-TOOLS (docker-container)? I've been using IIC-OSIC TOOLS (non-docker version) and it works well. Now I'm trying docker-version of IIC-OSIC-TOOLS, but I'm stuck at setup. When I try the flow of caravel_user_project, 'make setup' fails with errors below. % cd caravel_user_project % mkdir dependencies % export OPENLANE_ROOT=$(pwd)/dependencies/openlane_src % export PDK_ROOT=$(pwd)/dependencies/pdks % export PDK=sky130B % make test (snip) make[2]: Entering directory '/foss/designs/caravel_user_project/dependencies/openlane_src' Makefile:23: warning: undefined variable 'DOCKER_SWAP' Makefile:26: warning: undefined variable 'DOCKER_MEMORY' Makefile:42: warning: undefined variable 'ROUTING_CORES' /bin/sh: 1: docker: Permission denied make[2]: * [Makefile:114: pull-openlane] Error 127 make[2]: Leaving directory '/foss/designs/caravel_user_project/dependencies/openlane_src' make[1]: * [Makefile:84: openlane] Error 2 make[1]: Leaving directory '/foss/designs/caravel_user_project/openlane' make: * [Makefile:181: openlane] Error 2 I also tried without changing environmental variables (means, OPENLANE_ROOT=/foss/tools/openlane and PDK_TOOR=/foss/pdks), but 'make setup' also stopped due to permission errors in openlane. Other tools, e.g. xschem, klayout, magic, are working, so I think docker-container was installed correctly. OS is Windows 11 and Docker desktop is v.4.17.1.

@Akira Tsuchiya I think I remember having a problem when

OPENLANE_ROOT

and

PDK_ROOT

were sub-directories of

caravel_user_project

. Can you try this?

% mkdir openlane_test
% cd openlane_test
% mkdir dependencies
% export OPENLANE_ROOT=$PWD/dependencies/openlane_src
% export PDK_ROOT=$PWD/dependencies/pdks
% export PDK=sky130B
% git clone <https://github.com/fabless/caravel_user_project> -b mpw-9a
% cd caravel_user_project
% make setup

note that you cant run docker inside docker. I am not sure it is relevant to your issue, but it might be the reason

@Mitch Bailey Thank you for your reply. That stopped at the same error... Stopped at docker, so maybe @Arman Avetisyan’s comment is correct. I thought there is a way to use OpenLane because IIC-OSIC-TOOLS lists OpenLane on the available tools. Do I need some tricks, like docker-in-docker or docker-outside-of-docker?

From the

caravel_user_project

directory, the Makefile targets are setup to be run outside of docker and call docker, as needed. If you want to run Openlane directly, you could try

make mount

in the openlane directory and then

cd

to the design directory (you might need to add mount points), and then run

flow.tcl

(the openlane script).

In the image,

OpenLane

is installed local without using

Docker

. Presumably the executed makefile tries to install a docker-based OL environment parallel to the available environment, and/or it wants to touch files in the /foss/tools path (no root permission by default, therefore it fails). Anyways.. after cloning, can you try cd'ing to

<cloning-path>/caravel_user_project/openlane

and execute

flow.tcl -design user_project_example -tag foo -overwrite

? I just tried that and the flow finishes

Thank you for comments. @Manuel M ‘s way works! I was stuck to complete

make user_proj_example

and running

flow.tcl

has slipped my head… Many thanks
