[sdiy] ZyBo UCF ?

[Eric Brombaugh]

Scott,

It appears that Digilent hasn't yet provided the design materials needed 
for either ISE or Vivado builds targeted to the Zybo board. At the very 
least we'll need the .ucf or the board support package for building in 
the embedded design kit.

If you look on the main page for the board you'll see that they're 
promising to have a basic Linux distribution tailored to the board and 
that's not visible anywhere in the site. I suspect that as early 
adopters we've beaten them to the punch and the necessary support data 
isn't up on the website yet.

You might be able to cobble together a home-grown .ucf file from 
information in the schematic and user manual. The main thing I'd be 
concerned about with that approach is that there may be pins that 
require special configuration that isn't obvious from the available 
information. You might also be able to grab similar information from the 
zedboard site, but again there will be mismatches you'd have to resolve.

I believe that I'm going to wait a bit and see how this shakes out...
