problem with DDR2 SDRAM controller

i dont really sure which printout you need so i hope you want those:

warnings when compiling the libraries:

 
** Warning:  /<path for altera>/altera/quartus2/9.0/quartus/eda/sim_lib/stratixiv_atoms.vhd(1852): VITAL timing generic missing port reference(s).
(1076.4 section 4.3.2.1.2)

i dont really why there is a warning here because i didnt touch that file...

warnings when compiling the files:

i'm using liunx this command in linux environment :

vcom -O4 -work modelsim_work -93 -quiet -nologo -explicit -source <mega wizard path>/<device name>_phy_alt_mem_phy_seq.vhd

(all the other files necessary have been compiled without warnings)

the warnings for this file are:
