## If the interface timing constraints cannot be met then these can be relaxed by adjusting the values in this

## xdc file which is set to be processed after all other xdc files

## this also allows for the IODELAY tap delay setting to be adjusted without needing to modify the xdc's

## provided with the core

## All commands in this file can be used directly in the tcl command window if the synthesized or implemented design is open.

# The RGMII receive interface requirement allows a 1ns setup and 1ns hold - this is met but only just so constraints are relaxed
