In reply to:
The latter is simply not a tolerable situation
to me. It's simple math, if you want 10,000,000 trouble free
installations, then you're going to have to ensure that the
one-in-a-million combination of worst-case devices still works.
Is there really *any* other way to go about this?
Yes there is. Its called statistics. Instead of designing for worst case,
you design for 3 sigma, or 5 sigma, or whatever. It makes a lot more sense
even if you are designing atom bombs. Well, ok, maybe worst case is
necessary for that one.............
