Only thing I've got against Xilinx is their software. It's high time they
took ISE out to pasture and replaced it with something that actually...
well... *works* without crashing or going into 100%-CPU loops. A synthesizer
that can handle CPU cache constructs without generating faulty netlists would
be nice too... (another open bug: three years and counting!)

Other nice ISE features:
Dont try synthesising anything for Spartan6 (new synthesiser) without the
"keep hierarchy" option if you want it to work and not delete about 20% of
your design.
also beware of optimize for area, it makes designs that meet timing but dont
work (for complicated designs with embedded CPUs and multiple dual ported
RAMS at least)
The move to the binary project file was especially nice, now when ISE corrupts
the project file (which it does with fair regularity), you can no longer fix
it.
