Arpad,

You can always find an exception to a rule. That's one reason why there will
always be work for SI engineers. Glue logic jelly bean parts, available in many
different technologies at many different speeds are not a big problem here at
3Com. Nor, do I see our circuit designers mis-applying them.

Big, proprietary, in development ASICs that you get locked into before you are
even aware of the surprises are the problem.

For a supplier to say "well too bad, caveat emptor" is suicidal for both
supplier and customer. Jelly bean parts that are supposed to be all things to
all people are dismal failures for controlling quality. They're all over the
place from lot to lot. They do nothing well beyond saving their maker a pile of
money. Assuming anybody wants them.

The Japanese implemented something called "mass customization" on a stable,
standard process base. Lots are targeted at specific slots in a process window.
Besides, I've been hearing of various output circuit strategies to supplement
and complement the process control levers.

Are you telling me that you want life to be simple? Make one part for all
applications, let the process fall where it may, don't even worry about binning
out the result and let the customer worry about it?

Maybe I misread your ideas.

Roy
