After Mike Conn and Prof. Prince have addressed the history of SI, I would suggest the original advertiser, Optical Data Networking, or other hiring companies, to put down the knowledge of the history of SI as one of the "Position Requirement". I used to be a teacher and I know it is very important for a student or a working engineer to know the history of his/her own field. The knowledge will help the student or engineer to know the progress and development of this particular branch of science. When a complicated problem pops up in his/her lab or simulation run, he/she can trace this problem to the related area and solve the problem. I am happy to see there are many gurus in the [SI-LIST] to help younger engineers with history to solve their problems. Signal integrity is a "neat field", as pointed out by Prof. Prince. Working engineers need continuous help from professional consultants and gurus to learn this field. Francis Kai -----Original Message----- From: Dr. John L.

The endeavor we call SI now has been around possibly since the 50's, at major computer companies (or maybe just at one major computer company). I first developed and taught a university-level class (at Clemson University) which included "SI" elements in 1977--it was in fact a class in high speed digital electronics, so it included the circuit characteristics as well it must in this area. Bill Blood, thanks for help from your book! In 1983 the situation was becoming more serious, and here at Arizona we started a class in packaging which included "SI" elements. In 1984 we received major funding from SRC (which we still have, nearly 20 years later) to develop the science and algorithms behind what you now call "SI". Around 200 papers dating back to 1986, and numerous graduate students(dating back to 1986), have come out of this effort. Since 1990 or so there are other university programs (but not very many) which also address this area. So, there is little new under the sun today, just new names for things. And, just more fun to be had in a neat field.
