Breakfast Bytes: IEDM: All About Interconnect

Paul McLellan

The first week of December means it is IEDM, the International Electron Devices Meeting. This meeting pre-dates the integrated circuit and nearly pre-dates the transistor, so "electron devices" had a different meaning. In recent decades, th...

Breakfast Bytes: RISC-V: Real Products in Volume

Paul McLellan

I titled my preview of the RISC-V Summit RISC-V Summit Preview: Pascal or Linux? since it is clear that RISC-V is really the only game in town inside academia, but it still hasn't conquered the commercial world. So it's already Pasc...

PCB、IC封装：设计与仿真分析: 针对电气工程师的热管理基础——第四篇

Sigrity

作者：Lawrence Der 在热管理基础知识的第一篇中，我们讨论了电域和热域之间的二元性。第二篇中，我们研究了三种不同的热传输机制，并将它们与等效热阻相关联。第三篇中，我们使用热电阻的概念建立了系统的热等效网络，并确定了其等效连结环境（JA）热阻。通过这种方法，我们能够将热阻与系统的物理特性联系起来，并通过等效的热电阻方程直观地了解主要的热传输机制。现在，让我们来进入大家关心的究极问题：散热。散热片散热片是被动热传输器件。在将热量从IC封装传递到周围环境时，其热阻远小于由热对流和热辐...

Breakfast Bytes: The Mother of All Demos

Paul McLellan

It is the 50th Anniversary on Sunday of a demo that took place on December 9th 1968. It would go on to become known as "The Mother of All Demos" because it changed people's conception of what computers could do and set the agenda for mu...

Analog/Custom Design: Virtuosity: Designing a Row-Based Layout Methodology – Why does this Make Sense at Advanced Nodes Today?

Akshat

At advanced nodes, the complexity and volume of design rules have been growing exponentially. These challenges have contributed to the evolution of a row-based structured layout methodology, which lets you achieve a deterministic layout and increased layout efficiency.

Breakfast Bytes: Semiconductor 2018: Up and to the Right...But Memory Way Up

Paul McLellan

I was at a meeting of the ESD Alliance (probably still called EDAC back then) when someone memorably described the EDA industry as being like a water skier being towed behind the semiconductor industry speedboat. As long as the speedboat was going fa...

Breakfast Bytes: Benedict's Christmas Present...ation: The End of the Beginning

Paul McLellan

Every year Benedict Evans of a16z does a "big" presentation on the future of mobile and digital media. I put the word "big" in quotes because the other annual take on the internet is Mary Meeker's Internet Trends. Here is the 2018 version which comes...

Breakfast Bytes: Clayton Christensen on the Prosperity Paradox

Paul McLellan

Probably my favorite business book ever is Clayton Christensen's The Innovator's Dilemma. It is not just important, a book that anyone involved in management and strategy should read, it is also wonderfully written. I don't think I can go...

Breakfast Bytes: ICCAD and Open-Source CAD

Paul McLellan

Every year in November it is ICCAD, officially the International Conference on Computer-Aided Design. This year was the 37th, presumably meaning that the first one was in 1981. This year it was held in San Diego. I wasn't able to go, but several ...

PCB、IC封装：设计与仿真分析: 针对电气工程师的热管理基础——第三篇

Sigrity

作者： Lawrence Der 在热管理入门基础知识——第二篇中，我们研究了三种不同的热传输机制，并将它们与等效热阻相关联。为了加深对热域的理解，此篇文章中我们将使用热阻的概念来建立一个系统的热等效网络，并确定与其等效的连结环境热阻。作为电气工程师，我们必须保证的最基本的热要求之一，便是确保集成电路（IC）不超过其最高结温。根据热阻的概念，如果我们知道从IC结到周围环境的等效热阻、IC的最大结温和IC的最高环境温度，就可以估算出IC可具有的最大功耗，用下式表示： ...

Breakfast Bytes: "GDPR Is an Enormous Regulatory Own Goal"

Paul McLellan

During the summer I was on Twitter when I saw a tweet from Benedict Evans. He is an Englishman (yeah!) who Andreessen-Horowitz (usually just called a16z) brought over to the US to be a partner. The tweet said that "it was a gift to Google and Fa...

Breakfast Bytes: Do Cellphones Cause Brain Cancer?

Paul McLellan

One subject that regularly gets some traction in the news is whether cellphones cause brain cancer. Every so often a jury awards damages and the press makes a big deal about it, but usually it turns out mostly to be that a sympathetic plaintiff like ...

PCB、IC封装：设计与仿真分析: 针对电气工程师的热管理基础——第二篇

Sigrity

作者：Lawrence Der 在热管理入门基础知识——第一篇里，我们讨论了电域和热域之间的二元性。在这篇文章中，我们来聊聊三种不同的热传输机制，以及它们是如何与热阻相关联的，也是对之前的文章内容“封装/ PCB系统的热分析：挑战及对策”进行扩展。根据热力学第二定律，当介质中或介质之间存在温差时就会发生热传递现象，且该现象始终从高温处向低温处传递。在没有外部热源的情况下，介质之间的温差最终将达到热平衡，因此热传递机制其实就是不断努力使其介质和周围...
