Maximum width of FIFO

Hello, 

 

The maximum width of a FIFO in the IP catalog GUI wizard is limited to 256 bits. 

I need a wider FIFO and want to avoid cascading FIFOs. 

 

Will it work to manually change the generated HDL instantiation file to the width I desire (for example 1024 bits) ?

Did you try it? what were the results? 

Why not use two parrallel fifos?

No it isn't. IP user guides say

Note that you can manually enter a number that is not in the drop-down list.
