Hi,
I am under the process of migrating my design from an older PDK version to a newer version. In the older version, whenever I used to export my schematic to netlist via the export tool, at the end of the netlist of my block i used to get empty definitions of basic blocks like nfet/pfet coming from the pdk library. However, in the newer pdk version, these empty definitions are not there anymore.
So, whenever I run LVS using this netlist, the LVS tools complains that the source netlist references but does not define the subckt. The LVS passes the moment I add these empty definitions.
I have checked that the export netlist form is same in new and old pdk.
The old pdk is using IC6.1.6, the newer pdk is using IC 6.1.7. For LVS, Calbre is being used.
