RapidIO II IP Core Has Wrong Default TX VOD Setting in Arria V and Cyclone V devices - RapidIO II IP Core Has Wrong Default TX VOD Setting in Arria V and Cyclone V devices Description The RapidIO II IP core does not set the transceiver TX V OD value correctly in Arria V GX, Arria V GT, and Cyclone V devices. The default value violates the RapidIO specification. This issue affects all RapidIO II IP core variations that target a Cyclone V device or an Arria V device other than an Arria V GZ device. Resolution To fix this issue, add the following line to the Quartus II Settings File ( .qsf ) for your Quartus II project: set_instance_assignment -name XCVR_TX_VOD 50 -to <td> where <td> is the transmitter serial output pin to your RapidIO link. This assignment sets the TX V OD to the value of 500 mV. This issue will be fixed in a future version of the RapidIO II MegaCore function.
