    Hello, i would like to know how can i use the SDRAM DDR2 that comes in my PCI DEVELOPMENT KIT CYCLONE II EDITION.

    i am using the pinage that comes with the reference design and i instantiated the SDRAM2 in my SOPC using the DDR2 SDRAM CONTROLLER megacore function.

    I am using a PLL with the clocks of 166,67 MHZ (0 deg, 260deg and 210deg) that goes in the write_clk_to_the_ddr2_memory and resynch_clk_to_the_ddr2_memory respectvly.

    I get the following error:

    Error: Output clocks to SDRAM Not Found
