Event Description

Signal Integrity Webinar Series

Title: High-Speed Digital Field Visualization of Currents and Crosstalk

Date: August 15, 2017

Time: 8am PT / 11am ET

Sponsored by: CST - Computer Simulation Technology

Presented by: Yuriy Shlepnev, President and Founder of Simberian Inc.

Digital PCB and packaging interconnects operating at double digit Gbps data rates are usually designed formally with the minimization of the losses and reflections while maintaining the localization of each link. Can we understand better the major signal degradation effects by literally looking at the electromagnetic fields and current densities? This webinar is intended to introduce some basic concepts of interconnect behavior through the 3D visualization and animation of electromagnetic fields, currents and power flow densities. We begin with visualization and explanation of skin-effect, current crowding and field localization in simple single and coupled strip and microstrip transmission lines. The effects of some discontinuities in the reference plane will be visualized. Animation of currents and power flow density in vertical transitions such as vias and launches will be used to illustrate the localization principle and coupling effects.

Who should attend:
Signal integrity engineers and engineering managers interested in a deep understanding of how interconnects work.

Learn how to use visualization of electromagnetic fields, currents and power flow in the interconnect design. Understand where currents and power flow in uniform interconnects, what happens if reference conductors are compromised, and how traces and viaholes become coupled.
