DDR2 & Cyclone II EP2C8

edit: to be clear, i mostly want to know: has anyone used ddr2 with an ep2c8 speed grade 8? I am currently evaluating the possibility of using DDR2 memory, one device with x16 bit wide bus run...

Any update on how to fix this?

I've the same problem on a cyclone II dev board.

I've instantiated the design via SOPC builder and synthesis fails due to "DDIO output nodes could not be placed by the fitter"

renaming the ddr_sdram_0 in SOPC builder to ddr_sdram without the trailing "_0" did not fix the problem
