Matching the UCF files from MIG and ML403 turtoial demo

Hi,


I tried to use MIG to generate the DDR interface for FX12 on ML403
board.
And the UCF generated by MIG is not consistent with the one from the
ML403 tutorial demo.
So I matched it by hand. The address and data bus are OK, but there are

still some pins I don't know. Do you guys know their correspondence?
Thanks.


By the way, the DDR ram chip on ML403 is Infineon HYB25D256160BT-7,
i.e. 32Mx16bits, 266MHz. And the that on MIG is Micron MT46V32M16P-5B
operating at 266MHz, which is also 32Mx16bits. Are they compatible?
