lvs unattached port
Hello every body ,,,
I looking for some info about calibre interactive. I am using cadence virtouso to make some layouts for 0.35um tech and for DRC , LVS and PEX I'am using mentor calibre interactive. Also I use Cadence Virtouso for schematic capture.I could succussfully perform DRC. To do LVS by Caliber Interactive , I export my schematic using CDL feature in cadence to sp (Spice) format then run caliber LVS with layout in gds format but i got an error which I can not figure out?
Even I'm sure that the layout is same as schematic?
the error is :
