Understanding Voltage Drop Mechanics
By Ann Mutschler - 13 Apr, 2017 - Comments: 0

As a fundamental concept of electronic design, voltage drop ranks highly as one to understand well. I particularly appreciate when industry folks come up with creative ways to get the point across. Jerry Zhao, a product management director at Cadence and I were discussing how to best manage dynamic and static voltage drop, but I first asked him to explain the difference between the two. I p... » read more

Smart Antennas Come Into View
By Ann Mutschler - 09 Mar, 2017 - Comments: 1

Antennas are getting smarter, particularly in light of their increasing complexity, along with the intricacies of the environments — existing and new — they play in. There are interesting ways in which antennas are being integrated into the latest vehicles, some examples of which are in-vehicle approaches that range from a single antenna in the infotainment (behind the screen in front of... » read more

Adapting Formal
By Ann Mutschler - 09 Feb, 2017 - Comments: 2

With more pressure to make designs efficient — from a power perspective, as well as from an overall design view — finding what can be removed from a design is one step closer. As discussed in the article published today, “What Can Be Cut From A Design?” — sequential analysis, based on formal verification technology, is gaining traction. I specifically asked Mentor Graphics’ direc... » read more

What’s Missing In Deep Learning?
By Ann Mutschler - 12 Jan, 2017 - Comments: 0

It is impossible today to be unaware of deep learning/machine learning/neural networks -- even if what it all entails is not even clear yet. Someone who is intimately familiar with this area, and has some thoughts on this is Chris Rowen, founder of Tensilica (now part of Cadence), who is now a self-described hat juggler. He is still active Cadence several days a month, working technically on... » read more

Architecting For Energy
By Ann Mutschler - 10 Nov, 2016 - Comments: 0

Most of the time, electrical design engineers create their designs by putting in the functions first, then going back later to figure out what they can afford to shut down. But with energy harvesting, this is flipped, and the systems must be built to normally be ‘off,’ and with a clear understanding of the minimum power requirements. Also, most of the time, energy harvesting systems are ... » read more

Accuracy, Waveforms, And Power
By Ann Mutschler - 08 Sep, 2016 - Comments: 0

The entire topic of power analysis, estimation, and exploration never ceases to amaze me given that opinions on how to approach this are so varied. It is that diversity of opinions that makes it that much more intriguing. I’ve been particularly interested in how I now regularly hear that users are increasingly interested in taking activity from simulation and emulation and using that to dr... » read more

Accuracy Is Relative
By Ann Mutschler - 11 Aug, 2016 - Comments: 0

I've been doing some thinking on the concept of accuracy lately in my article, Does Power Analysis Need To Be Accurate? And, I’ve come to the conclusion that there isn’t a single conclusion to be had. Accuracy is very relative to the task at hand, as well as the use case, and the very specific power requirements. And maybe the focus shouldn't be always on the accuracy, but on what the chan... » read more

Power Confounds, Challenges
By Ann Mutschler - 14 Jul, 2016 - Comments: 0

I have to admit I’m always surprised to hear that design teams are not using tools to the fullest extent possible, leaving valuable power saving opportunities on the table, until I remember how daunting it is to get it all right without tremendous experience, expertise, and the right tools. I’m also always fascinated to learn about less-obvious effects from power. To this point, Aveek... » read more

Simulation To Protect Us
By Ann Mutschler - 16 Jun, 2016 - Comments: 0

I hate to say I told you so, but, I told you so. Back in 2011, I wrote this article, Cell Phone Radiation: Taboo Topic, Interesting Science, and have since kept my eyes open for proof of what I’ve feared for some time now: that our bodies may be adversely affected by the radiation emitted by everything from the myriad electronic devices we carry close to our heads and bodies to WiFi hotspo... » read more

It’s All About The Data
By Ann Mutschler - 12 May, 2016 - Comments: 0

Ah, the wonders of math and physics — they do make the world go ‘round, do they not? And even in the world of chip design, of course, it is the fundamental understanding of the physics of electricity, materials, metals, etc., that it is all possible. I just wanted to stop for a moment to marvel at how those fundamental understandings of the math and physics of things have been abstracted... » read more
