How do I write the LEF view of a power pad

I have a set of pads for use in a design and I was wondering which attributes should I put on each pin.

Let's say it has the following pins:

   - inh_vdd, inh_vss, CORE, PAD where the first two are for the pad rings, the CORE pin is to use in the die and the PAD pin is the bonding pad.

I guess CORE would need:

   CLASS CORE

   USE POWER  (or GROUND if this happened to be a ground pad)

What about the inh_vdd and inh_vss? Theyu would not have the CLASS CORE, but would I use USE POWER/GROUND on them too?

   USE POWER (or GROUND)

   SHAPE ABUTMENT

And the bonding pad? Should I put it in the LEF? Or would that cause confusion to innovus or Voltus? And what attributed would it use? USE POWER/GROUND only?

Do I need anything in the LEF to indicate that the pin CORE and the pin PAD are essentially the same thing, just different places on the same power pad?
