Chapter 1: ML605 Evaluation Board
The ML605 XC6SVX240T FPGA DDR memory interface performance is documented in the
Virtex-6 FPGA Data Sheet: DC and Switching Characteristics (DS152) [Ref 4].
The ML605 DDR3 64-bit wide interface has been tested to 800 MT/s.
The DDR3 interface is implemented in FPGA banks 25, 26, 35, and 36. DCI VRP/N resistor
connections are only implemented banks 26 and 36. DCI functionality in banks 25 and 35 is
achieved in the UCF by cascading DCI between adjacent banks as follows:
CONFIG DCI_CASCADE = "36 35";
CONFIG DCI_CASCADE = "26 25";
Table 1-4 shows the connections and pin numbers for the DDR3 SODIMM.
