Let’s explore the available layers:
You can also verify this is the active PDK on gdsfactory:
gf.pdk.get_active_pdk().name
'sky130'
Now, let’s explore available symbols for the components:
# dir(sky130)
sky130
<module 'sky130' from '/home/runner/work/skywater130/skywater130/sky130/__init__.py'>
Let’s try exploring an example basic nfet:
c = sc.sky130_fd_pr__rf_nfet_01v8_aM02W1p65L0p15()

Explore it’s ports:
c.pprint_ports()
