When the LogiCORE IP Tri-Mode Ethernet MAC v5.1 is generated in ISE Design Suite13.1, the example design targets an xc7v285tffg784-1 device.Because this device is no longer a valid part, the tools error out if the example design implementation script is run in ISE Design Suite 13.2 software.
Solution
If the LogiCORE IP Tri-Mode Ethernet MAC v5.1 is generated in the ISE 13.2 software, the target part in the example designUCF is changed to7vx485tffg1157-1.
