Honored ContributorI use StratixII EP2S60 rohs, in my application i need to use 64 block of M4k. In my board i have 255 blocks. When i added to my SOPC the 64 blocks, and i start simulation he appear to me this 2 error:
1/ selected device has 255 ram location of types m4k. however the current design needs more then 255 to succesfully it. 2/ can't fit design in device. How can i resolve this problem please?
Honored ContributorTake a look here:

Honored ContributorRedesign the RAM so it is more efficient.
Honored ContributorChange the device, just to see if it solve your problem.
sds[]Honored ContributorHi all,
I have exactly the same problem => I changed the device, and verified all settings.. but always the same error message when compiling "can't fit design in device" Any other suggestion please ?Honored ContributorDo you have some inefficient ram?
Honored ContributorFifo's often use more memory than one would expect. e.g. a Fifo of 1280 by 32 uses 16 M4k but only 40960 bits are used. If you split it into two concatenated Fifo's (building a compound Fifo) you can restrict the M4k usage to 10.
