If you try to get hardware design using axi_ethernet core you may to need this recommended constraints:
AXI_Ethernet v3.00.a - Recommended Constraints for AXI-based Ethernet Systems
The above link doesn't exists any more :( Here is carbon copy of them:
This Answer Record provides links to zip files with the recommended constraints for the AXI_Ethernet v3.00.a core logic. The constraints for the Ethernet pins themselves are not included. These constraints have been tested on specific development boards and some attributes such as IDELAY, IDELAYCTRL, and GTP/GTX locations can change in custom implementations.
Designs with AVB Endpoint Enabled (C_AVB = 1)
Virtex-6 Hard TEMAC Implementations
Virtex-6 Soft TEMAC Implementations
Spartan-6 Soft TEMAC Implementations
Designs without AVB Endpoint Enabled (C_AVB = 0)
