[IBIS-Users] Use of Rref declaration in differential signals

Hello All,

Suppose I am using the differential receiver and has the  input 
termination resistor of 100Ohm at the input.
And suppose we have mentioned the Rref as 50Ohm (Rload/2) and R_load as 
50Ohm.
During the validation are we suppose to still add the 100Ohm at the 
input of the receiver or Rref takes care for it.

How actually Rref and R_load differ.

Thanking you
Shrikant GK
