LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v2.5 - Vivado - 7 Series - Timing errors sometimes seen on path to and from Transceiver
When using the Ten Gigabit Ethernet PCS/PMA v2.5, timing errors are sometimes seen seen in the example design on paths to and from the 7 Series GTX or GTH transceiver when using Vivado Design Suite 2012.3 .
These timing errors do not occur when the GTX or GTH transceiver is locked to a specific location.
Example constraints are shown below:
