Where is the sky130A.tech file located? I have checked it inside the skywaterpdk I cloned from GitHub and also open_pdk but I think it's not present anywhere.

It is in Open PDKs git. https://github.com/RTimothyEdwards/open_pdks/tree/master/sky130/magic

Where did you install it? It is usually installed in /usr/share/pdks/sky130A/libs.tech.

I used the default settings. So yeah it's supposed to be inside that folder in pdks/sky130A/libs.tech

Strange... I don't know what is happening because I may be using an older version of Open PDKs. It had some updates recently.

Okay. Anyway I am uninstalling and reinstalling it so I will post an update if anything changes.

For now, try calling magic -T with the path to your git clone. It may work. By the way, you can just use magic -rcfile *sky130A.magicrc, if you're not using it this way already.

I haven't been actually. I am new to all this so still following those steps at vsdflow and openciruitdesign.com

It can be located at a different place. Try this path “/usr/local/share/pdk…."
