What Happens When Routing Over Splits In Power Planes

Multidisciplinary product creation powered by your unconstrained network. Work concurrently across design, sourcing, and manufacturing with real-time insight. 35+ Years of Excellence: https://www.altium.com/develop?utm_so... In this episode of Altium Academy, your host Zach Peterson dives deep into the topic of routing over splits in power planes. Inspired by Bert Simonovich's paper in the Signal Integrity Journal, Zach takes you through the process of setting up a test board in Altium Designer to simulate the effects of routing over power plane splits. From understanding the stack-up of a six-layer board designed for high speed to exploring the implications of power layer splits, Zach guides you through the intricacies of this common scenario. The video demonstrates how to perform simulations in Altium Designer and Simbeor to analyze the impact of different gap sizes on S-parameters, focusing on both single-ended and differential signals. Key points covered include the importance of differential pairs in mitigating impedance deviations, the influence of power plane splits on return loss at various frequencies, and considerations for optimizing vias to minimize discrepancies in simulations. The video provides valuable insights for engineers working on high-speed designs and emphasizes the necessity of simulation to ensure optimal signal integrity. Don't miss this informative episode! Follow along in Altium Designer, gain practical tips, and learn how to make informed decisions when dealing with power plane splits in your PCB designs.
