and at the end of the comparison file it states:
Warning: Equate pins: cell sky130_fd_pr__nfet_01v8 has no definition, treated as a black box.
Does someone experienced this behaviour? I understand that netgen is not reading the transistors in the extracted file, then no comparison is made.
Device classes user_analog_project_wrapper.spice and user_analog_project_wrapper_layout.spice are equivalent.
Verify: cell user_analog_project_wrapper_layout.spice has no elements and/or nodes. Not checked.

this created a subcircuit instance of the top layout. The netlist matches uniquely after commenting out the lines containing the ports and the subcirtuit declaration (i.e., including only the instances of our cells)
ext2spice -o cell_ext.spice
