How do I find where P&R has placed my BRAM?

[Symon]

Hi,
I use Data2Mem to load a V2Pro BRAM. I'd rather not lock the position of the
BRAM just yet, so how do I automate the process of finding where place and
route has put my BRAM? Using FPGA viewer is getting to be a pain.
TIA, SYms.

you need a .bmm file (Block RAM Memory Map) ... it contains the
names of the blockrams...

If you put this file in the project tree (asigned to the toplevel) then
place&route will create a second .bmm file with the location of the
blockrams ...


I'm sorry - I don't know how to create these files manually ...
In my case they are created by the EDK (platgen I think)


bye,
Michael

Hi Michael,
Thanks, that fixed it! You leave out the LOC in the BMM, and then P&R copies
the BMM and adds the LOC in. Just to clarify to anyone else reading, in my
build process, I 'added' the BMM file to the top level EDIF file in
Navigator.
Thanks again and cheers, Syms.
