LogiCORE CPRI v1.2 - Default slave CDC FIFO depth too small

Description

The default slave CDC FIFO depth of 8 is too small for correct operation. This value does not provide the necessary margin for phase drift. The depth should be 16 for correct operation.

Solution

This will be fixed in CPRI v2.1, scheduled to be released in 11.1 IP Update 1.
