We have purchased ML555 Board from xilinx.
we want to modify the ddr2 controller in order to suit with our current design .
1-/ we have seen verilog files for the ddr2 controller provided in the CD.Unfortunately we works with VHDL language, where can I get the VHDL files?
2-/ What is the freq max when running the controller? knowing that the ml555 fpga has a speed grade of 1.
1. Run the Memory Interface Generator (MIG) in CoreGen. Choose VHDL.
2. I believe it is 333. The MIG will tell you. Also see XAPP858.
