and at the end of the comparison file it states:
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.
Does someone experienced this behaviour? I understand that netgen is not reading the transistors in the extracted file, then no comparison is made.yrrapt

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)yrrapt
