Is there an existing .def file for the empty caravel_analog_user_project? I'm attempting to use openlane to place and route the digital portion of my design within the footprint of the analog user project area, but in order to route to the pins properly it requires a def file. There are lef and gds files around on github, but I haven't been able to find a def file.

I created this one just now by loading the empty user project wrapper into magic and then running

extract all

and

def write

. I think it's sufficient.

Keep in mind that the power and ground needs to be manually connected anyway

Perfect, thank you Tim! That was exactly what I needed
