cyclone III

Hi,

I use the cyclone 3 board

I want to create the schematic file .bdf for the standard version comes with the card

in the compilation phase I find the following error:

Error: The DQ group with DQS pin "mem_dqs_to_and_from_the_ddr_sdram[1]" has invalid DQ group assignments

Error: The "2.5 V" I/O standard and/or the "Default" current strength on the pin "mem_dm_from_the_ddr_sdram[1]" is not supported for DDR/DDR2 external memory interfaces

can you tell me how I solve
