Abstract
The ability to accurately model and simulate signal integrity is of utmost importance in high-speed
electronic designs. While there exist tools for 3D parasitic extraction and ground bounce analysis in
complex geometries, we also need many design aids to develop design rules and correlate simulation
results with measurements. In this paper, we discuss some of these essential tools and the theories
behind them.

Dr. Ching-Chao Huang is Senior Vice President of Business Development at Optimal Corp. Previously,
he was Signal Integrity Manager at Rambus, where he was in charge of signal integrity modeling,
simulation, and characterization. He was also R&D manager at TMA (which is now Synopsys),
responsible for such trend-setting parasitic extraction products as Raphael and Raphael-NES. He was
Advisory Engineer at IBM, where he designed high-speed interconnects, and developed several widely-
distributed parasitic extraction and circuit simulation programs (., COSMIC and ASXwr). Dr. Huang
is an IEEE senior member, and he received his BSEE from National Taiwan University and MSEE and
. from Ohio State University. His R&D interests include high-speed interconnects, circuit
simulation, putational ics.

Introduction
The interconnect parasitics has been known to be a bottleneck for high-speed electronics design, and the
signal integrity modeling, simulation, and characterization is now ing part of the mainstream
design and verification flow. There exist mercial software to perform 3D parasitic
extraction1 and ground bounce ana
