when using MIG tool (ML605),how do i select the pin for each DDR3 port?

I have post this question last time ,but still i can not understand how to select the pin for DDR3 .

 

Does any documentations  depict the archirecture of ML 605  FPGA ,for example bank,row,colunm allocate in the board .Because i don't understand how to select the right pin for each port (ie  dq[0],LOC=?)  in the ucf,so i can't make sure whether my design is right .

 

I just follow the step in the design ML605 MIG Design files.zip, but I don't know why ?If you can give me some advice i woule be very appreciate .

 

Thanks very much!

The information you seek may be found in the ML605 schematics, pages 5, 6, and 15.

 

Row and Column addresses are multiplexed on the same address signals.  These signals are labeled DDR3_A0 through DDR3_A15 on the ML605 schematics.

 

Bank Address signals are labeled DDR3_BA0 through DDR3_BA2.

 

I don't understand your difficulty with the reference design .UCF file.  Please explain.  It is available for (registered) download from the Xilinx website, seach for rdf0041.zip

Is that mean  when selecting the pin/bank in the MIG generation step,I must follow the schematics  to find the right pin for the port ,otherwise the design might not right?

You should follow the reference design .UCF file or the schematics.  They both have the same information.
