#
#   This file holds all of the nets for the various
#   calibration and pull-down resistors that are needed
#   the the  Select I/O Banks  and  the MGT Transceivers.
#


#
#   -----------------------------------------------------------
#
#    Now include the  Digitally Controlled Impedance  DCI
#    calibration resistors.  For each Select I/O Bank the
#    DCI calibration resistors is  240 Ohm  from the  VRP
#    pin to Ground.
#
#       We have these for HP Banks: 65, 66, 67, 68  -  R101:R104.
#
#       We have one of these for HP Bank 71  -  R105.
#
#       We do not include them for the unused HP Banks: 70, 72.
#
#       The DCI VRP pins do not exist for the HR Banks: 84, 94.

#
#    Now include the  pull-down  resistors on the  VREF  pins
#    that are required for any Select I/O Bank that uses an
#    I/O standard that uses a differential input buffer and
#    uses an internal source of VREF  (VREF_Internal or VREF_Scan).
#    These are 1k Ohm from the VREF pin to Ground.
#
#       We have these for the HP Banks:  65, 66, 67, 68  -  R106:R109.
#
#       We have one of these for HP Bank 71  -  R110.

#       We do not have these for the unused HP Banks: 70, 71, 72.
#

#
#    Now includ the required MGT Termination Calibration Resistors
#    for the GTH and GTY transceivers.   Thsese 100 Ohm resistors
#    from the  MGTRREF  pin to the  MGTAVTTCAL  pin and then to
#    the  MGTAVTT  pin.
#
#    The traces from these resistors to the  MGTRREF and
#    MGTAVTTCAL pins must be symmetric, matched in length
#    and under 0.5 Ohm.
#
#       We need all 4 of these MGT Calibration Resistors
#       that are located near Quads:  125, 130, 226, 231.
