Consistently Design PDNs That Deliver Reliable Performance at the Right Cost

Too often, PDN designs work inconsistently, and techniques that work in some scenarios seem to fail inexplicably in others. This book explains why and presents realistic processes for getting PDN designs right in any new product. Drawing on 60+ years of signal and power integrity experience, Larry Smith and Eric Bogatin show how to manage noise and electrical performance, and complement intuition with analysis to balance cost, performance, risk, and schedule. Throughout, they distill the essence of complex real-world problems, quantify core principles via approximation, and apply them to specific examples. For easy usage, dozens of key concepts and observations are highlighted as tips and listed in quick, chapter-ending summaries.

Coverage includes
• A practical, start-to-finish approach to consistently meeting PDN performance goals
• Understanding how signals interact with interconnects
• Identifying root causes of common problems, so you can avoid them
• Leveraging analysis tools to efficiently explore design space and optimize tradeoffs
• Analyzing impedance-related properties of series and parallel RLC circuits
• Measuring low impedance for components and entire PDN ecologies
• Predicting loop inductance from physical design features
• Reducing peak impedances from combinations of capacitors
• Understanding power and ground plane properties in the PDN interconnect
• Taming signal integrity problems when signals change return planes
• Reducing peak impedance created by on-die capacitance and package lead inductance
• Controlling transient current waveform interactions with PDN features
• Simple spreadsheet-based analysis techniques for quickly creating first-pass designs

This guide will be indispensable for all engineers involved in PDN design, including product, board, and chip designers; system, hardware, component, and package engineers; power supply designers, SI and EMI engineers, sales engineers, and their managers.

持續設計可靠且具有適當成本的PDN



太多時候,PDN設計的效果不一致,某些情況下有效的技術在其他情況下卻無法解釋失敗。本書解釋了其中的原因,並提供了在任何新產品中正確設計PDN的實際流程。作者Larry Smith和Eric Bogatin憑藉60多年的信號和電源完整性經驗,展示了如何管理噪音和電氣性能,並通過分析來平衡成本、性能、風險和進度。在整個過程中,他們提煉了複雜現實世界問題的本質,通過近似量化核心原則,並將其應用於具體示例。為了方便使用,書中突出了數十個關鍵概念和觀察結果,並在章節結尾列出了簡要摘要。



內容包括:

• 一種實用的從頭到尾的方法,以持續達到PDN性能目標

• 了解信號與互連的相互作用

• 確定常見問題的根本原因,以避免它們

• 利用分析工具高效地探索設計空間並優化權衡

• 分析串聯和並聯RLC電路的阻抗相關特性

• 測量元件和整個PDN生態系統的低阻抗

• 從物理設計特徵預測迴路電感

• 通過電容器組合減少峰值阻抗

• 了解PDN互連中的電源和地面層特性

• 當信號改變返回層時解決信號完整性問題

• 降低由晶片上電容和封裝引線電感產生的峰值阻抗

• 控制PDN特徵與瞬態電流波形的相互作用

• 使用簡單的基於試算表的分析技術快速創建初步設計



本指南對於所有參與PDN設計的工程師都是必不可少的,包括產品、板卡和芯片設計師;系統、硬件、元件和封裝工程師;電源設計師、SI和EMI工程師、銷售工程師及其管理人員。
