UltraScale/UltraScale+ Interlaken - CDC-10 Critical Warning seen core_tx_reset, core_rx_reset, core_drp_reset

Description

When I create a CDC report for the Interlaken Core, I see the following Critical Warning:

CDC-10 Combinatorial logic detected before a synchronizer

The combinatorial logic is composed of several asynchronous signals going into the synchronizer for the fabric reset logic.

Solution

The warnings for the reset signals can be safely ignored.
