Now if you interactive tool could have used the acronym
Field Effect Labor Diminisher, you would have had
Sein Feld
And that would have been funny.....8-)

Actually, when the engineering group ("Signal Integrity
Engineering") developed and supported the program we
pronounced it "Sine". I guess it was the German
pronounciation of "ei". When the software group
got hold of it they started to say "Sane" instead. I
don't know why, but "In-Sine" is not funny at all.
enough historical trivia?
cheers
Rich

For those on the list who are fans of hooked on
phonics or Ex NBC Thurs night comedies you might
have missed the clever naming. The DEC tool, if
I remember properly was pronounced 'Sane', hence
their interactive tool, was 'Insane'.
Engineers are such funny and clever people. No wonder
they always get the girl.......obligatory 8-) ;-)

My introduction to DEC's in-house IV curve based simulation program
(SEIN) was in about 1986. Soon after, the interactive version (InSein)
was developed. We nicknamed it TurboSpice. You could draw a net, add
drivers and receivers, and it would pop up waveforms on your screen in
less than a second.
We used SEIN as a quick first check on all board nets. It would
simulate every single net on an Alpha CPU motherboard, complete with
cache, memory SIMMs/DIMMs, and plug-in cards (PCI, ISA/EISA) in less
than half an hour. It would generate and list all the wire delays, and
flag any overshoot problems.
Of course it was not considered as accurate as SPICE. But it was great
as a quick "filter" to see where the problem nets might be, and then you
could take those and investigate further with SPICE. And the speed made
it good for doing "what-ifs" on your entire board, or looking at bus
loading effects.
