Small bump in the road here.

caravan_tb

is looking for

libs.ref/sky130_fd_io/verilog/sky130_ef_io__analog_pad.v

but I can't find that anywhere

@Olof Kindgren It is part of

open_pdks

https://github.com/RTimothyEdwards/open_pdks/blob/master/sky130/custom/sky130_fd_io/verilog/sky130_ef_io__analog_pad.v . You probably have built the pdk with an old commit for

open_pdks

.
