Designing PCBs for Edge AI: DDR, PCIe and HDI

Edge AI puts compute, memory and camera links onto small boards, so density and speed rise together. Part 3 covers stackup and impedance, constraints defined before routing, length and phase matching, and BGA breakout with microvias, all live in Xpedition.

This is Part 3 of 5 in the GSAS EDA Insights Series Webinars, PCB Design edition. Every session uses the same edge AI board, designed in Siemens Xpedition for the series, and includes a live demo.

What’s covered

• Stackup and impedance set up before routing starts.
• DDR constraints from a template, and one LPDDR4 byte lane routed and tuned.
• A PCIe differential pair routed live.
• Microvia fanout under the SoC and plane generation.

Who should attend

PCB layout and hardware design engineers working on high-speed or high-density boards, and design leads planning edge AI products.

Session time

Ranjith Kumar Jadam, Technical Director and Solution Architect, presents with Sampath Radha Krishna and Bhavana Deevi, Field Application Engineers. All three are from GSAS.
