I hope that Mr. Mcgrath and others are not shy to respond to this list
because of my presence here. Anyway, I'll be at PCB Design Conference West
for the next two days.
As to the matter at hand, I thought of writing about this but did not have
time. Changing the "CN" designators to "J" or "P" would not only be more
standard, but it would also probably solve the signal integrity analzyer
problem. As to which is to be used, "J" or "P", that is a whole other can
of worms. Some people just use J.
But that standard I know has J indicating a stationary connector and P a
mobile connector, relatively speaking. Generally a P plugs into a J. If
both are mobile, then the male (with pins) is P, the female (with sockets)
is J.
The signal integrity analyzer we presently have is only a taste of the
future; it is not a mature tool. I'd expect it to have user-definable
models in the future, just as the 3-D board display will, I expect, have
user-definable models.
(I'm not panning the signal-integrity analyzer. I haven't used it; some
users have reported good results with it. But I don't think we can alter
the models.)
