// Description:  This wrapper file instantiates the full Virtex-5 Ethernet 
//               MAC (EMAC) primitive.  For one or both of the two Ethernet MACs
//               (EMAC0/EMAC1):
//
//               * all unused input ports on the primitive will be tied to the
//                 appropriate logic level;
//
//               * all unused output ports on the primitive will be left 
//                 unconnected;
//
//               * the Tie-off Vector will be connected based on the options 
//                 selected from CORE Generator;
//
//               * only used ports will be connected to the ports of this 
//                 wrapper file.
//
//               This simplified wrapper should therefore be used as the 
//               instantiation template for the EMAC in customer designs.
