3D modeling methods in SERDES Designs: Is via behavior causing your SERDES designs to fail?



Do you have a clear understanding of your Multi-Gbps channel’s performance? Are you accounting for the potential signal losses due to discontinuities, such as a poor via design? If not, the slightest misstep could cause your SERDES designs to fail.

Engineers take great care in designing vias for high-speed differential signals, especially for return-current and common-mode immunity. By using proper via-modeling methods early in the design process high-speed designers can configure correct via structures and accurately predict via noise effects.

In this webinar, we will evaluate the behavior of vias through 3D electromagnetic simulations and provide a methodology for optimizing via designs. We’ll also use post-route verification to validate via behavior for a better understanding of a via's effects on multi-gigabit channels.

What You Will Learn

  • How to evaluate via behavior
  • How to optimize via design
  • The importance of 3D EM (electromagnetic) simulation
  • Proper pre- and post-route via modeling techniques
