DDR SDRAM in custom board

May 23, 2007 0 Replies

Hi everyone. I have a virtex II pro in a custom board (sundance board) and a Micron MT46V16M16. I use edk to create a design with PowerPC and the DDR. I select custom board and I finally get my design. The problems is the following:


- sys_proc_reset only work with "PORT Dcm_locked = dcm_0_lock" and not with the default "PORT Dcm_locked = dcm_2_lock". I suppose that dcm_module blocks don't work fine.



- This could be related with the second problem: Net fpga_0_GEN_DDR_CLK_FB LOC=; I have read the ucf file provide by the company and I don't find any feedback for the ddr.



How could I resolve this?. How could I integrate DDR in my powerpc design?. It is very important, because my program has to be loaded in this sdram.



Thanks
