LogicoreIP Aurora 64B66B v8.0 - Incorrect GTX RX Delay Attribute


When generating an Aurora 64b66b v8.0 core in the Vivado 2013.1 tool, RX Delay attributes of GTX are not set correctly. This answer record helps with the correct attribute settings required.


The core will automatically set the RX Delay attributes as follows:

RXDDIEN                = tied_to_vcc
RXDLYBYPASS      =  tied_to_ground

According to the GTX User Guide, these attributes should be set as follows when RX Buffer is in use:

RXDDIEN                = tied_to_ground
RXDLYBYPASS      =  tied_to_vcc
