Initializing memory in NCSIm

I want simulate the post syntesis netlist with NCSIM. I have some memory implemeted with some 4k ram block and i need to initialize them.On megawizard blocks i use mif and hex files, but in simulation don't run. How can I do? On the Altera web site i find this

http://www.altera.com/support/software/nativelink/simulation/ncsim/eda_pro_ncsim_func_sim.html

but i don't understand were put the line with parameter. My memory are always not initialized.

Someone can help me?

    Where the web page you listed says "functional simulation", that means simulating with your RTL files. Your post said "simulate the post synt[h]esis netlist." If you are simulating with a .vo generated by Quartus, see the timing simulation link on the web page you listed.

    With a .vo, the memory initialization data will be inside that file. The simulator won't use .mif or .hex files. (See http://www.alteraforum.com/forum/showthread.php?p=2154#post2154.)
