Cadence - Schematic vs Layout
I think I've already answered your other post, but here it is again:
Problem looks like it's here:

cell 'inverter layout IRUWB_TRANSMITTER' from the layout does not bind to anything in the schematic.

Have you double checked that this layout instance has a corresponding schematic instance in your LVS'd cellview?
They've got to match or the LVS will not complete and throw errors.
