There was a time when power integrity (PI) was treated as an afterthought—a minor checklist item at the end of a hardware design cycle. You tossed a few extra decoupling capacitors near the FPGA or processor, crossed your fingers, and hoped the board wouldn't glitch. Those days are officially over. With today's high-performance silicon drawing massive currents at sub-1V levels, power delivery networks (PDNs) have become some of the most complex, high-risk components of modern hardware...

With contributing authors Heidi Barnes (Keysight), Steve Sandler (Picotest), and Kathleen Love (Signal Edge Solutions Importing a SEPIA measurement into Keysight ADS gives you all of the information you need for your design to achieve stability in less than a minute, even if it’s a non-LTI system. In this blog, we will discuss how to leverage these tools to get actionable insights on a design’s stability. In a world where VRM control loops are no longer consistently linear, time‐invariant...

Learn about how crosstalk in power distribution networks (PDNs) is a significant issue amplified by ground loops.
