Cost-effective implementation of these high-bandwidth channels across high-volume manufactured products requires analysis of many design and manufacturing parameters.
This Siemens white paper presents a new approach for the systematic analysis of SerDes channel compliance at 25Gbps and above. Using a 100GBASE-KR4 electrical backplane design, the methodology reveals the system's sensitivity to various design variables, intelligently explores the design space, and provides a high-level description of the automation involved in the analysis process. Demand for higher bandwidth has greatly increased the signaling data rates for SerDes.

We’ve seen many changes over the past few years, and nowhere are they more evident than in the world of sourcing components. Sourcing has become one of the biggest challenges facing PCB designers and design engineers today. Gone are the days of procuring parts from a single source, and communication between stakeholders and distributors is critical. But as we learned in a conversation with I-Connect007 columnist Kelly Dack, PCB designers can use certain layout strategies to plan for the unexpected, such as leaving extra real estate so that smaller components can be replaced by larger, readily available parts if the originals become “unobtainium.”
Happy Holden, I-Connect007
For this issue, Happy Holden provided a range of options for designers who are seeking to conserve materials in their next design. He also offered an example of the relative cost index, or RCI, that he developed at HP exclusively for PCB design. With this RCI, designers can figure out the relative cost of a new design compared to an eight-layer through-hole board. We hope you can use this handy formula on your next design job.

Nolan Johnson recently spoke with Brad Griffin, product marketing director for Cadence Design Systems, about Cadence’s Matrix solver technology. They discuss its use as a multi-disciplinary field solver as well as Cadence’s focus on thermal analysis and utilizing the power of the cloud.
