RGMII mode on V4 Hard Tri-EMAC core

Hi Mikhail,

yes, you have to implement the DDR registers.
The PLB_TEMAC core includes a PLB to TEMAC interface (PLB-IPIF with
FIFO etc and IPIF to TEMAC) and the embedded TEMAC. Now you have to
route the signals from the TEMAC to the external PHY by yourself. For
this you should read the Virtex4-TEMAC documentation (UG074).
Use the PLB_TEMAC to connect the hard TEMAC to the PPC and do the rest
yourself.

In the UG074 are BUFG used for some CLIENT_TX and CLIENT_RX signals.
The BUFGs are not used in the hard_temac core !!

Have fun
Florian
