Re-use it is. Back in the 80's I was working in a workstation
company and came across this 3 men company in Santa Barbara.
They sold us this timing tool and a "transmission line
calculator" with these behavioral driver model. I liked it,
developed SI analysis methodology around it, worked with
them to fine tuned the tool and convineced my company to make
it a standard physical design requirement. I won't say even
they claimed using behavioral driver model is their invention
but certain they were the first to package it in a CAD tool.
Hats off to Larry, Chuck and Chris.
And when did IBIS came out ?

Chris,
I thought he was saying he was a sharp engineer who got a (software)
supplier to write a spec for him.... Some companies value employees who can
do the leverage and re-use game.
