WARNING:NgdBuild:931 - The value of SIM_DEVICE on instance 'RX_CLK_BUFR' of type
   BUFR has been changed from 'VIRTEX4' to 'VIRTEX5' to correct post-ngdbuild
   and timing simulation for this primitive.  In order for functional simulation
   to be correct, the value of SIM_DEVICE should be changed in this same manner
   in the source netlist or constraint file.
