Picoblaze bit file block ram remplacement

Started by paxl13 December 4, 2009
Hi everyone,

I've been playing with fpga since a couple of time and I can't find
the answer to my quesiton. I have
a picoblaze in a design of mine and I want to update the bitstream
without having to re-"build" my design
entirly ( to save time ). I'm using linux and thus the tool given with
the picoblaze can't work. I found out
picoasm ( http://www.xs4all.nl/~marksix/picoasm.html ) + this page
( http://www.labbookpages.co.uk/fpgas/picoBlaze.html ) witch give all
the info I should need but I have a problem. How can I locate the
blockram
witch the placer has placed my program. The script that the site give
use this command :
xdl -ncd2xdl vga.ncd
This output a vga.xdl file witch should contain my Block ram and it's
position but it is nowhere to be found.
I'm using Xilinx 10.1...

Do anyone has an idea ?
Thanks a lot for your input,
paxl13
I feel ugly !,
When you try to update a block ram, always assure yourself THAT Xilinx
didn't
have removed it from the design !!!

Sorry for this,
paxl
