Bradley Brim had
a busy DesignCon 2014. Not only did the Cadence Senior
Staff Product Engineer spend time demonstrating technologies in the Cadence
booth and talking with customers, but he presented a paper with his colleague Mike Kang (Cadence applications
engineering director) and Xilinx's Chris
Wyland (senior staff signal integrity engineer in the System Signal
Integrity Group) and Romi Mayder
(manager of transceivers and IOs at Xilinx). (Brim also found time to organize and participate as a speaker in a
panel session on system-level power integrity).
The paper centered on a key
challenge in chip-package and board design today: simultaneous switching output
As the team wrote in the
"The technical objectives were to understand the
requirements for low-frequency spectral content of frequency domain models, how
to best store/transmit this information and how to most successfully apply the
information for SSO analyses with TD circuit simulators. The goal was a best
known method (BKM) applicable to various FD model extraction tools and various
TD circuit simulation tools."
Below, Brim describes the rationale behind the paper and the
technological analysis. You can read the full
paper here and review
the slides here.
