#              Base Function FPGA IO signals used for the connections to the TP FPGA
#             -=============------------------------------------------================

#     Original Rev. 02-Apr-2012
#  Most Recent Rev. 02-Apr-2013 find location for these signals whithout interfering with other signals
#
#       BF to TP connections for support of S-link return channels
#       ========----------------------------======================
#
# If the TP function needs to support S-link protocol (rather than G-link)
# the CMX will need to receive the return channel of the Duplex S-link.
#
# The SFP optical receiver from the 2x S-link connections (DAQ and ROI)
# cannot be directly received in the TP FPGA because all 36x MGT receivers
# of the TP FPGA are already used with the 3x12 Avago optical receivers.
#
# The SFP optical receivers are instead routed to MGT receivers located
# on the BF FPGA and the serial signal received is sent from the BF FPGA
# to the TP FPGA via two differential Select IO signals.
#
