Hi, If I use "Import SPICE" and the port are missing. Is it safe to add them manually? I have 2 hierarchies, the top 1 doesn't have port and the bottom does.

@Or Dicker If you’re exporting from xschem, Set

SImulation

->

LVS netlist: top level is a .subckt

before netlisting to get a top subckt with ports. You should be able to add them manually too.

Thanks!
