I've been troubled by the version of pdk for a long time, I don't know how to see his version number

@Tim Edwards Used to be that

open_pdks

kept the

skywater_pdk

repo around so it was easy to check the installed version of the pdk there with

git describe

. However, with the current volare installation, I could not find what

skywater_pdk

commit was used. There is a json file

pdks/volare/sky130/versions/41c0908b47130d5675ff8484255b43f66463a7d6/sky130A/.config/nodeinfo.json

, but the information there wasn't too helpful in regards to

skywater_pdk

. Is there any way to tell which commit of

skywater_pdk

was used to build the pdk?

I can add the commit number for

skywater-pdk

itself, although the open_pdks installer uses nothing from the

skywater-pdk

repository; the only content is from the submodules themselves, which is why they are called out individually. I only clone the top level repository because it requires running

make timing

from the top level (possibly

make timing

can be run within the submodules; I have not checked that possibility). But I do not know where this

@:libraries/...

content comes from. Every entry should be followed by a commit hash except for the entries in

build

, which are version numbers/git tags. The JSON file you posted, though, it outdated, because there is supposed to be another section at the bottom called

reference

, which doesn't make any difference here, but I thought that Donn had merged that into Volare, so I'm wondering if the file above is up-to-date.
