But ROM and RAM on FPGA are different things. You should not, of course,
use RAM to hold ROM contents, but it should be perfectly OK to use ROM
to hold ROM contents. I don't know what kind of FPGA you are using, but
for example Altera 10M02 has 12 kB of RAM and separate 12 kB of ROM,
which is most likely too small for your purposes, but bigger chips have
more.
