Hello, I am trying to pass the lvs of I/O cell available from pdk. There is no schematic but auCdl, aulvs, symbol, hpiceD ans hspiceS models. I am unanble to pass lvs in Calibre and I get the message "source could not be read", no matching .SUBCKT for cell name etc. I tried black boxing using LVS options and also used command LVS BOX cellname. But this do not work. Any suggestions.
