Title: Black boxing in calibre for IO cells
Post by vlsi_design on Jul 30^th, 2022, 9:49am

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.

The "source could not be read" error means the source netlist is not available for the LVS run. Please check the netlist file path.
