Well not having a lot of luck with the xilinx wise application.
Its a 6.5 GB tar and after a good 5 hr plus download the tar doesn't open

But 6.5 GB to work a cpld. Seems crazy to me.
I also had no luck two weeks ago with the single file download.
The web install worked ok, however. It downloads many smaller
files. I think my very slow DSL connection is to blame here. :-(
The web-installer has the benefit that you can skip larger pieces you do
not use. That would reduce the download time significantly. Xilinx a bit
to improve on their installations as well as how apps work. I have had
to tweak systems in... ehm... interesting ways... and that just to run
their installation stuff. Last time it worked better, but it's a bit
hairy still.
Two years ago, when I still lived in Berlin, Xilinx used to have one of the
few servers that were capable to max out my (then) 16 MBit/s link.
At the computer club I get a 1 GE pipe if I need it.... not only the
local link... but into internet too. I don't think they max that one
out. Too much in-between.
@ Ulrich:
Did you see a show stopper with the Xilinx Coolrunners?
I have used them before and liked them. Really fast and they
consume close to no power. I'd like to deploy them for something
jitter-critical very soon.
There should be some interesting choices among the Spartran generations.
But for simple divider-stuff, CPLDs is very nice. I still think that
trying to do a one-chip solution would be hard to compete with a simple
external resynchronise DFF. Let the CPLD do the state-updates and the
DFF do the low-jitter timing. It's a fairly cheap solution anyway.
Cheers,
Magnus
