Inferring a ROM

What's the nature of the values being stored by the ROM? Are they random or do they fall naturally from some simple formula? You can always write a script to save you the typing. I avoid using MIF/HEX files unless I need to update my memory contents without recompiling the design. Instead, I describe the RAM and initial contents purely in HDL. Quartus II will infer initial contents from the HDL source, e.g.

signal rom : my_rom_t := initialize_rom();
