I am trying to implement the Xilinx DDR SDRAM memory contoller detailed in
XAPP253 and am having problems with the data strobe line during a read
cycle. I need to somehow add a delay onto the incoming data strobe signal.
In Xilinx apllication note 688 it describes a way of building delay elements
using LUTs. Does anybody know how this can be implemented? I am programming
in VHDL and targeting a Virtex II Pro.
