RX Deskew DCFIFO Overflow Causes DisplayPort to Fail Link Training

Description

The DisplayPort IP core fails link training when the RX deskew DCFIFO overflows. This issue occurs when the DCFIFO rdusedw is not incremental by 1 in the over stringent deskew DCFIFO read condition.

Resolution

There is no workaround for this issue.

This issue is fixed in version 15.1 of the DisplayPort IP core.
