Hi,

ram size is 256*8 bits = 512 * 4 bits and so cleanly fits 4 M512 blocks.

all your fifos are too large for M512 and it makes sense to use M4k

for example the smallest fifo of 512*23 will fit cleanly 23 of M512 blocks or will fit 3 of M4k blocks with 512 bits wasted !!!

I am a bit disappointed it seems your compiler didn't follow my claim about wasting. It didn't mind that and was more concerned to hold on to the graininess just in case.
