Virtex-6 Aurora 64b/66b - Data loss in the RX side

Description

Aurora 64B/66B core loses data on the RX side when Clock Correction (CC) characters are received.

Solution


The Aurora 64B/66B core uses fabric FIFO for implementation of Clock Correction logic. When there are few ppm differences between the READ clock and WRITE clock, the READ side logic loses data when CC characters are received.

The fix is in hand and is currently being regressed. Please contact Technical Support to obtain the fix.
