How do you initialize a ROM for simulation?

I am using a 1-Port ROM in a max 10 device. When I configured the IP I selected and generated an intel hex file for memory content data. But during simulation the values are all 0. Is there a way ...

Hi KLohr!

First of all, I would like to recommend using *.mif file instead of hex file for simulation of initial content in ROM.

Hope that helps.

OK, so I switched to using *.mif file and I still get all 0's in my simulation. Any further ideas? The ROM .v file has the following line in it. But it doesn't seem to be looking at it:

altsyncram_component.init_file = "lookuptable.mif",
