Guys.
This must seem quite trivial, but how can I tell how many block rams I
am using in a xilinx coregen'ed fifo. Example, how many block rams are
being used in a 256bit by 32 deep fifo.

thanks

Well, the easy way is to select "Display Core Footprint" when you generate
the core. You can also just regenerate and select this to find out about
an existing core.

When you generate the memorey keep pressing the next botton before you
chose the generate and tha last page at the bottom section have
"information panel" in which it will tell you exactly how many Block
are used.

if the core already exsist you need to use ReCustemize and than under
current project and just press again the next until you reach the last
page and there will be again the "Information panel"

Have fun.

thanks

When you generate your coregen, tick the "display core footprint" option.
If you do that , then on successful generation of the core, the tool
will show you
the resource usage.

Also, based on the knowledge of available BRAM Size, you can calculate
the number of BRAMs
For example, in your case, you will need at least 8 BRAMs because of the
width requirement you have.
Hope this helps.
