Hello, can someone direct me towards the GitHub of sky130, I am working on a project where I need the liberty files. Also is there any documentation on the standard cells, information about the devices used in standard cells their vth etc. I found this: https://github.com/google/skywater-pdk But the last update is from an year ago

Looks like open_pdks gets data from Efabless repositories, for example: https://github.com/efabless/skywater-pdk-libs-sky130_fd_sc_hd
