subckt that is not commented out.
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

block has no pins. Maybe that’s why there is no instance of untitled

.
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

subcircuit name may be a problem. Do you get the same results if you change the symbol and schematic name?Mitch Bailey
