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 Is your error similar to this? https://skywater-pdk.slack.com/archives/C016UL7AQ73/p1636175203114900

@User No.

@User Can you post your error?

@User yes..

@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:

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

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

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.

Hi @User, searching on

slew_margin

, I found this

I ran the command make test to first check the design and it gave no errors

You might try the following, but I'm just repeating what other people have said.

cd OpenLane/
git fetch
git checkout tags/2021.10.25_20.35.00
make openlane
make pdk
make test

Okay will try this.

Since you've made changes to some files, it won't overwrite them automatically. You can try this

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

Got the issue solved. Just edited the.tcl file in scripts 😅
