FIFO issues

[Jeff Mrochuk]

Here's one for ya.
 
I tried to compile my fifo, and even with only 32x8 its gigantic (14% of our 
chip)
So I took a look at their design and it turns out the reason its so small is 
because it uses ESB bits.  If you disable ESB bits on the altera fifo, our 
640x8 fifo is 103% of the chip.
 
Looks like we may have to be a bit more creative in our display, maybe empty 
it as it fills.  I'd like to know how commercial hardware does it, maybe it 
just has giant fifo hardware.
 
In the mean time, do you know if you can tell quartus to use ESB bits on your 
own designs?
