By default, xschem will not create a top level subckt. You need to select Simulation -> LVS -> Top level is a .subckt before netlisting.
Also be sure that your layout contains ports. When you create the text for the ports in magic, be sure to check the this is a port box.Sam Burns

You should see something like this
type=subcircuit
format="@name @pinlist @symname"
template="name=x1"
There may also be an lvs_format line. If you are missing the format or lvs_format line, try adding the format line as above and re-netlist.Sam Burns

11/22/2024, 11:18 PMuntitled subcircuit name may be a problem. Do you get the same results if you change the symbol and schematic name?Mitch Bailey
