Thanks Jack! I'll check the tutorial.

Hi Franco,
Here's an ancient tutorial -

Hi all,
Thanks you for your replies. I actually found the same problems David and
Andrew mentioned. In bigger models there is a lot of line overlaid, and you
don't have control over the block size. I didn't know about mdl2m, that is
a big time saver! Because most of the time I was manually
To add to what Dave has said. I found that having no control over the
relative size and placement of the blocks when using xBlocks made it hard
to see what was happening, making the design write-only and hard to debug.
Generating scipts can be tedious though. The mdl2m.m script in the
I could be wrong, but as I recall, the block diagrams created via xBlocks were
(at least at the time) not very conducive to visualizing the structure of the
diagrams (e.g. lots of lines/traces overlaid on top of each other). This was
not a serious problem when everything worked as it should,
i don't know much about xblocks, so can't add much to jack's comments,
except:
about a dozen years ago chris dick and others at xilinx recommended casper
use xblocks,
so hong chen tried it out, and ported several of the casper dsp blocks.
i think it worked well, and hong chen liked xblocks, but
Or.. move to verilog/VHDL and use black boxes? :)

Hi Jack,
I see. We actually found problems when trying to script xBlocks within an
xBlock, we got some weird block connection error, but I guess that is
something solvable with some debugging. We'll evaluate if we stay with
xBlock scripting or we switch back to standard simulink scripting.
Hi Franco,
I don't think there's any reason not to use xblocks. Someone can
correct me if I'm wrong.
Several years ago there was a quest to move the whole casper library
to xblocks -- https://github.com/casper-astro/xblocks_devel/ -- but it
never seemed to get traction and the original libraries
Dear Casperites,
I've recently been playing around with the creation of block libraries and
I found out about Xilinx's API for programmatic model creation (xBlock). I
find it particularly convenient because you don't have to explicitly
position the blocks, as the software does all the positioning
