Why PCBs Respin and How to Stop It: Checks During Design

A respin means another fabrication run and lost weeks. Part 2 covers where errors enter a design, why each later stage costs more to fix, and what checking during design means in practice, with real errors planted on the series’ edge AI board and caught live.

This is Part 2 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

• Where errors enter a design, and why each later stage costs more to fix.
• What checking during design means in practice for signal, power and manufacturing, using Xpedition with HyperLynx analysis.
• Live catches on the edge AI board: a DDR topology issue at schematic, DC drop on the SoC core rail, a manufacturing defect before release, and an electrical rule violation.

Who should attend

PCB and hardware design engineers, signal and power integrity engineers, design leads and ECAD managers.

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.
