Hello,
I'm using a Stratix-III development kit (DK-DEV-3SL150N) and trying to use the DDR2 SDRAM (U17) to work in my own FPGA configuration. I've verified that I can access the memory using the tutorial that came with the kit. I'd like to understand how all this works. Anyway, I'm getting the below error message during the fitter phase.
Error:Bidirectional pin DDR2_DEVA_CK_N with a pseudo-differential I/O standard must use the output enable control signal on the output buffer.
I've had a look at the pin definitions in the development kit (that worked) and mine and the look the same. Where in the assignment editor do I make this assignment for the "output enable control signal"? Or am I on the wrong path? Please advise, thanks in advance,

You probably need to run the pin assignment script for the UNIPHY. Look in the quartus tools menu for "run script". There will be a list of scripts there and one of them indicates that it will configure the pin assignments for the UNIPHY (pin_assignments.tcl).
