@User have strictly followed the installation instructions up to the “make user_proj_example” command. Then, openlane is launched as you can see in the log that I have attached. Indeed, I didn’t have any “/project” folder but the Openlane program seems to use those. I didn’t change the default path of any files and set every environment variables as required. I just noticed that the maglef/user_proj_example.mag contains: ” string GDS_FILE /project/openlane/user_proj_example/runs/user_proj_example/results/magic/user_proj_example.gds”

The Make command runs the flow using a docker container and the /project dir will be present inside the container. Don't worry about that. This seems to be a problem with PDK_ROOT. Do you have this variable set to the proper path?

Yes my PDK_ROOT is set to the root of my project such as <my-root-project>/pdk as required in the export PDK_ROOT=$(pwd)/pdk in the https://docs.google.com/document/d/1x7ubNSmfUb0xBmkW8iK-H1fOHXtxRlUGQaaAhjPEJA4/edit#

You can check if this dir exists: $(PDK_ROOT)/sky130A

It exists but the file .tlef is missing in it, that’s why I’ve got the error

Hello, we found the error! Since the

STD_CELL_LIBRARY

env variable is set to an optional library, the default

sky130_fd_sc_hd

lib is not downloaded and the

sky130_fd_sc_hd.tlef

cannot be build. Is it possible (in a further version) to build the pdk for different standard cell libraries?

yes see the linked google doc above. In the installation section you can see the part where you could choose different cell libraries
