Free signal integrity? How understanding anisotropic materials and tolerances could increase performance at 112/224Gbps and beyond

2026-03-19T14:52:49-08:00

The paper includes a study of the influence of anisotropy on the channel performance and examines methods to extract out the level of anisotropy. The overall goal is to achieve better than 2% measurement-simulation correlation in impedance profiles. This approach allows for optimized geometries and controlled geometry designs.

Advances in VNA-based Signal Integrity Tools and Techniques

2026-03-19T16:17:38-08:00

In this presentation, we demonstrate new de-embedding techniques integrated into VNA firmware that make frequency-domain signal integrity measurements easier, more accurate, and less error-prone. We also present new tools to predict system response to arbitrary time domain signals.
