Hello everyone, I am trying to install Open lane but the make test command gives an error. I have already installed open_pdks and skywater-pdk separately. What should I do?

@User Looks like there's a problem with your pdk installation. You said you installed 
open_pdks
and 
skywater-pdk
separately, but that is only part of what you need to to create 
PDK_ROOT
. In the 
Makefile
, you can see this line:
Copy code
pdk: skywater-pdk skywater-library open_pdks build-pdk gen-sources
If you've already done 
make skywater-pdk
and 
make open_pdks
, you might be able to get by with
Copy code
make skywater-library
make build-pdk
make gen-sources
but I'd recommend just rebuilding the pdk from scratch to be safe. If you don't want the pdk to be in 
/home/pranav/OpenLane/pdks
, you can
Copy code
export PDK_ROOT=<some_directory>
before 
make pdk
.

@User Thanks for the solution. I rebuilt the pdk but now there is an another error...

See the 
FileNotFoundError
? If that file is not there, then there may have been a problem building the pdk. Did 
make pdk
give you any error messages?

No make pdk ran correctly without any error

Can you see the 
/home/pranav/OpenLane/pdks/sky130A/libs.ref/sky130_fd_sc_hd/techlef/sky130_fd_sc_hd.tlef
file?

No 😅. I will rebuild the pdk I guess it was not downloaded properly.
@User Hello!! I ran the docker container to check the spm design but got an error. It say "-slew_margin is not a known keyword or flag" and the slew margin can be seen in or_resizer.tcl file.

Hi @User, searching on 
slew_margin
, I found this
Does that thread help?

I ran the command make test to first check the design and it gave no errors
This error popped up when I was in the docker container
Should I again install openlane and run the following make commands? @User

You might try the following, but I'm just repeating what other people have said.
Copy code
cd OpenLane/
git fetch
git checkout tags/2021.10.25_20.35.00
make openlane
make pdk
make test

@User Tried running above command it gave an error..

Since you've made changes to some files, it won't overwrite them automatically. You can try this
Copy code
git checkout -b local_changes
git commit -a -m "local changes"
git checkout tags/2021.10.25_20.35.00
make openlane
make pdk
make test
