Wizards of Electromagnetism

In Paul Rako’s recent Voices article my pals Larry Lerner (Agilent) and Greg Edlund (IBM) give their perspectives on the state-of-the-union in signal integrity. Greg highlights the importance of using not only SPICE but also EM solvers.

The electromagnetic behavior of interconnect systems is becoming more difficult to subdivide into independent components. Signal-integrity engineers need to understand how components interact with each other so they don’t miss important effects by making the models too small. In the future, successful signal-integrity engineers will use 3-D field solvers in the same way they used SPICE in the early days: to enhance their understanding of system behavior.
