Is there a LEF available which has the

user_analog_project_wrapper

pin locations? (We’ll be generating a subset of it via PnR - ideally going right to its digital-facing pins)

You can read the GDS into magic and then write out LEF.

Copy code

cif istyle sky130(vendor)
gds read user_analog_project_wrapper
lef write -hide

should give you

user_analog_project_wrapper.lef

with all the appropriate pins.
