ADS5263 along with FMC-ADC adapter in Virtex 6 device

Hello,

I am using Virtexn 6  evaluation kit along with the FMC-ADC adapter and ADS5263EVM from texas instruments.
i would like to write a vhdl code to control the LVDS DDR outputs provided from the ADS5263EVM to Virtex 6 FMC pins on a ML605 board.
I am really confused about implementing the ddr logic in my custom ip..

if you could send the example code to me as well that'd be great

thanx in advance
