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?

<@U021BTRSZ5H> Is your error similar to this? <https://skywater-pdk.slack.com/archives/C016UL7AQ73/p1636175203114900>

<@U021BTRSZ5H> 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=&lt;some_directory&gt;```
before `make pdk`.

<@U017X0NM2E7> 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 :sweat_smile:. I will rebuild the pdk I guess it was not downloaded properly.

<@U017X0NM2E7> 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 <@U021BTRSZ5H>, searching on `slew_margin` , I found this

<https://skywater-pdk.slack.com/archives/C016H8WJMBR/p1635378105037000>

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? <@U017X0NM2E7>

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```

<@U017X0NM2E7> 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
```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 :sweat_smile:

<@U017X0NM2E7> Thank you.. Got everything running properly :grinning::blush:.
