Virtex-6 GTH Aurora 64b/66b - RXBUFRESET and BUFFER_CONFIG_LANEx Updates

Description

Version 6.1 of the Aurora 64b/66b core needs an update for the RXBUFRESET initialization sequence and the value for attribute BUFFER_CONFIG_LANEx.

Solution

The RXBUFRESET for the GTH in the Aurora 64b/66b core is routed from the TX clock domain to the RX clock domain. The current way of synchronisation between the 2 clock domains can cause the pulse to be lost.

The value for the attributeBUFFER_CONFIG_LANEx configures for automatic operation, but it should be configured for manual operation.

For information on both issues, please see (Xilinx Answer 43591) and (Xilinx Answer 42927) has more specific information about the BUFFER_CONFIG_ATTRIBUTE.
