Hi, I connected the layout to wrapper pads, ran LVS, I got: Circuits match uniquely with port errors. The undriven pads could be the reason? everything looks fine in the log

If it says there are port errors, then those should show up in the output.

This is the comparison log, I couldn't find where is the issue

@Amirhossein zanjani Looks like your top cell is

user_analog_project_wrapper_empty

. You’ll probably want to change that to

user_analog_project_wrapper

. How are you creating the source side netlist? Is it from xschem? How are you running LVS? Is this the precheck

lvs.report

output?

Yes, it is from xschem. The layout is manually connected to the wrapper (not openlane) and the file is netgen LVS log

Are you adding pins to the xschem netlist with

_uq?

suffices? You probably don’t want to do that. There is an extraction option you can use to connect disconnected nets that have the same text. It is dangerous, but the

user_analog_project_wrapper

is set up with disconnected nets that have the same text. Instead of

extract unique

try

extract unique notopports
