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...

Breakfast Bytes: The Fermi Paradox

Paul McLellan

It's the day before Thanksgiving. Breakfast Bytes will be dark Thursday and Friday. But today, the day before a break, I write about something that has little (okay, no) connection to semiconductors and EDA. I thought today I'd write about the Fermi ...

PCB、IC封装：设计与仿真分析: 如何一劳永逸轻松对接三维建模专家

Sigrity

回想一下那个坐在角落里被一群博士们簇拥着的同事；人人都想找这位3D专家给自己的设计做3D结构分析。他/她好像无所不能，会使用一般人难以掌握的软件工具。但是问题是，即使他/她分析完你的3D结构并告诉你需要做出哪些调整之后，你仍然面临着大量的工作。你可能需要几天才能完全理解他/她想要的改变，继而再需要几天在layout设计工具中重新绘制该结构。再分析、再更新，这样的往复可能会持续好几次，直到最终的设计令大家满意。我们的Allegro和Sigrity工具可以帮你解决这个问题。只要你能说服3D...
