Hi! Recently downloaded Caravel Analog User Project and after installing it I tried opening the user_analog_wrapper.mag, but end up getting the following error:

Cell user_analog_project_wrapper has technology "$PDK", but current technology is "minimum"
Use command "tech load" if you want to switch technologies, or use
"cellname delete user_analog_project_wrapper" and "load user_analog_project_wrapper -force" to force the cell to load as technology minimum

I ran "export PDK_ROOT=/home/AIC/caravel_user_project_analog/PDK" before downloading the pdk using volare. Any tips?

This is an error that the openlane developers introduced into the repository and never corrected, although there's an open ticket for it (that I created). Just edit the .mag file and change "$PDK" in the second line to "sky130A". Setting a variable won't have any effect, because magic does not recognize a variable name in that position in the file.
