2014.2 - Vivado_DRC: (REQP-52) - GTXE2_CHANNEL cell gtxe_xx: Use of the GTGREFCLK is reserved for test purposes only. This has the lowest performance of the available clocking methods and can degrade transceiver performance.

描述

I am receiving the following DRC Error in my design:
 

GTXE2_CHANNEL cell gtxe_xxx: Use of the GTGREFCLK is reserved for test purposes only.
This has the lowest performance of the available clocking methods and can degrade transceiver performance.

解决方案

In the past this message had the severity of "Advisory", however, in the 2014.2 release the severity of this message was upgraded to "Error".


As per (UG476), GTGREFCLK is a reserved pin which should not been used in your design.
