Things are getting stranger:

I reinstalled the evaluation board kit, and opened the example (board update portal) project.

then I generated the SOPC system, and I noticed that the sdram.v was not created. other files such as sdram_alt_ddrx_controller_wrapper.v and sdram.ppf (what ever this file do ) were created.

It seems that all of the other components (sgdma, cpu, tse_mac) don't have any problems.

one more important thing, when the SOPC starts up (or when I refresh the system) I get a warning:

Warning: altmemddr3: Catalog mismatch; expected v10.1 but found v10.0

on my machine I have version 8.1, 10.1 and 12.0 so I don't see why only the DDR3 will find that particular version, and whether or not it should make a difference.
