In looking at the SemiWiki analytics, one of the top search terms that brings traffic to our site is ARM, just about anything ARM. In fact, that’s what the next SemiWiki book will be about. Yes, ARM is that interesting. While EDA is also one of our top search terms, EDA+ARM will get the most views, absolutely. And let’s face it, bloggers… Read More

How to detect weak nodes in a power-off analog circuit?
Most analog cells have a power off mode intended to reduce power consumption. In this mode, all the circuit branches between the supply lines are set in a high impedance mode by driving MOS gates to a blocking voltage. This is a somewhat similar situation to that in tri-state digital circuits.
When a branch is set in that high impedance… Read More
Do you check your circuit DC stability?
Most analog designers are aware of loops stability. In most cases, stability is understood as AC stability, the goal is ensuring enough phase (gain) margin so as to avoid the loop to enter oscillation. But prior to studying AC stability, DC stability should be questioned. What is that DC stability only few people think of?… Read More
Distributed RLCK Models for Transmission Lines in High Speed Applications
Design engineers frequently struggle with transmission line design and modeling. We can define a length of interconnect that contains more than 1/100th of a wavelength as a transmission line. This seems to be the breakpoint where distributed effects to start to become significant. To improve circuit performance these long … Read More
The Great 28nm Debacle!
40nm was a big node while I was Director of Foundries at the IP company Virage Logic which was later acquired by Synopsys. 40nm was big because the top fabless companies multi-sourced designs from one foundry to another with relative ease to get the best wafer prices. It was also the node where some of the big IDMs went fab-lite moving… Read More
Mentor Graphics @ SEMICON West 2014
Mentor is again the most represented EDA company at SEMICON West this year. I strongly advise Cadence and Synopsys to get more involved because EDA may be where electronics begins but semiconductor manufacturing makes all of our hard work come true, absolutely. Paul McLellan, Beth Martin, and I will be blogging live, I hope to see… Read More
Electronics growth positive around the world
Electronics production growth has turned positive in 2014 for all key geographic regions. The graph below shows three-month-average change versus a year ago for electronics production in local currency through April 2014. Total industrial production is used for Europe (EU countries) and South Korea since electronic production… Read More
Internet of Things (IoT) Startup Showcase @ SEMICON West!
It’s hard to believe that SEMICON West is upon us once again at the Moscone Center in San Francisco. This is the premier semiconductor conference for cutting-edge equipment, processes, and materials, to solutions to today’s design and manufacturing challenges. Remember, it’s not what you know (because … Read More
Is SOI Really Less Expensive?
Introduction
There have been some claims made recently that planar Fully Depleted Silicon On Insulator (FDSOI) is less expensive than bulk planar processes and FinFETs at various nodes. Some of these claims suggest that FinFETs in particular are significantly more expensive. My company, IC Knowledge LLC produces the most widely… Read More
The “Key” to Reality
If we wanted to reduce the definition of authentication to its most Zen-like simplicity, we could say authentication is “keeping things real.” To keep something real you need to have some sort of confirmation of its identity, as confirmation is the key (so to speak).… Read More
