Inferring a ROM

Thanks for your reply. Its a quarter wavelength sinusiod. Currently I'm using MATLAB to output a file with the appropriate VHDL formatting.

I did use Quartus' genmem command, but I'd rather write my own model and have Quartus infer the 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();

Look at the Verilog and VHDL templates in the Quartus II GUI for more examples.
