[...Xilinx devices...]
These are easily programmed using zero-cost
development software you
can download from the Xilinx web site,
I'm not sure it's really fair to call running someone else's
binary-only software "zero-cost". That kind of risk is relatively
expensive, in trouble and safeguards if all goes well, in putting the
machine back together one way or another if not.
If, as I fully expect to be the case[%], it's also software that runs
only under closed-source licensed-for-$ operating systems, it's not
anything like zero-cost, since it demands buying RTU the relevant OS.
[%] What little I could find on the Xilinx webpages was not clear about
downloading - it seems to want a login of some sort - but seemed to
be all about XP, apparently meaning Windows XP. Perhaps I missed
something because their pages are too lynx-hostile....
