Generating small rom & ram for Cyclone 3

MegaFunction wizard doesn't seem to allow using Logic Cells for small roms & rams in Cyclone 3 as it allows in Cyclone 2. I don't want to use a M9K for a small memory block. Anyway to get aroun...

Hi,

Using Quartus II 9.0SP2, the megawizard allows one to select LEs for RAMs but not ROMs. This seems to apply to all supported device families. Weird, I must say.

Suggestions:

a) hope for the best, ie, set it to "AUTO" and let the tools balance registers vs M9Ks

b) do not use the ROM megafunction, use just plain HDL for your ROMs.
