How to Simulate ROM Megafunction in Altera-Modelsim

[Altera_Forum]

Hi, 

 Could any one help me out on how to simulate ROM Megafunction,   Actually I tried both by generating .hex as well .mif format , but I couldnot get the results.   It is a single port ROM ,   With clock , address and q as signals,.   When I simulate I see the outputs (q) to be zero every where. Is there any procedure to follow to read the actual values ??/     Hope any one respond and help me out ..   Thanks, Srinath.

A possible reason is that your initialisation isn't read. If so, it could be seen from a simulation warning. Generally *.hex is required for ModelSim, and must reside in ModelSim project directory, that's where the modelsim.ini and *.hdp project files are located. The ROM content can be examined also in simulation memory window.
