What are the differences between a permissible exposure limit and a threshold limit value?

How could we inherit parameters from schematic to a layout netlist?

Those parameters are user defined parameter given in CDF and netlsiting in schematic.

Hi, I am new to cadence. I started out designing an inverter and ran LVS. I made sure that the labels are matching in both schematic and layout. But I run into the following error while LVS  stating that "No matching sub-ckt found for NFET and PFET". Can someone provide insight into this?
