OneSpin Takes on Formal Verification Metrics
“Is this it?”
“Yeah, I think so. Drop it off here.”
“Whaddaya mean, ‘I think so’? If they don’t get the money, we’re dead.”
“I know, I know. But you can’t see any addresses here. It’s all so beat up I don’t really know which house is which.”
“And you had to go without a map. Real smart.”
“There is no map, you moron! Not even Google will drive through this neighborhood. This is, like, No Man’s Land. I just want to get in, make the drop, and get out. Look, there, those guys are watching us. Givin’ me the creeps.”
The Intersection Between Sailing and Engineering and the World's First Foot USB Controller
In this week's Fish Fry, Amelia chats with Bill Neifert (Carbon Design Systems' Chief Technology Officer) about the benefits of Carbon's pre-silicon software development and architectural analysis, and how his love of sailing intersects with his passion for engineering.
Also this week, Amelia gets into the nitty gritty details of a new 3D printer specifically created to print chocolate, and she investigates how the new foot-operated digital interface unveiled by KMI might not be all that they claim it is.
Amelia has a Lattice ECP3 Versa Development Kit to give out this week, but you'll have to tune in to find out how to win.
Many of today’s integrated-circuits (ICs) are designed to operate in low-power modes to accommodate greater analog-digital integration, faster operating frequencies, and battery-powered applications. During semiconductor manufacturing test, the majority of logic is often activated concurrently to facilitate detection of many faults within a small set of patterns to reduce test time. Activating all the logic at once uses more power than these low-power devices were designed to function under, which can cause them to fail or burn out during test.
This divergence in functional power versus test power means that the test application has to allow power thresholds to be set so that overstressing devices beyond the functional design and operation is avoided.
Happy Birthday, the United States of America. How does it feel to be 235? You really have done well since you took the training wheels off and started riding your bicycle by yourself.
Many societies have what historians call “Foundation Myths” – stories that explain how a community was established. Some myths explain societies through the acts of gods, others through the actions of people, either imaginary or real people. For example, the founding myth of the City of Rome was that twins, Romulus and Remus, who were brought up by a she-wolf, founded the city that was the heart of the Roman Empire.
Bruggeman Takes On EDA
At the Design Automation Conference this year, Amelia had the pleasure of sitting down with Cadence CMO John Bruggeman and they chatted about all sorts of things...including why he thinks the "style" of EDA needs re-invention, where he thinks EDA360 is headed, and why he believes EDA isn't getting its fair share of the electronic market revenue pie.
Also this week, Amelia has a Lattice ECP3 Versa Development Kit to give out to one lucky listener, but you'll have to tune in to find out how to win.
Synopsys’ OSG Group Helps Designers Put Photons in the Right Place
Way back in the 80s, I remember talking to someone about the delicacy of putting together the lens stack used to project the light that exposes circuit patterns onto silicon wafers. Those machines must seem hopelessly primitive today (pellicles were just being introduced), and yet, even then, the optics were a delicate matter.
As described to me, the lenses were carefully ground and assembled with thin sheets of paper between them – like the wax paper that keeps slices of deli cheese from sticking together. To assemble, you carefully positioned one lens over its adjoining one, and, when alignment was perfect, you gently slid the paper out. If you got it wrong, there was no return once the paper was removed: the lenses were so precisely ground that the cohesive attraction between the two lenses would make any further minute adjustments impossible.
Who’ll Use the Next Generation of Design Tools?
The Von Neumann architecture is a miracle of efficiency if you count the algorithmic complexity that can be completed by any given number of transistors. If you’ve got enough transistors to create a 32-bit processor plus peripherals plus enough memory to store a decent size program, you can execute an enormously complicated algorithm.
Where Von Neumann isn’t so efficient is in the amount of computation for a given amount of power, or in the number of computations in a given amount of time. Those battles are won handily by custom, parallel hardware like we might create in an FPGA, or in a custom, algorithm-specific block in an ASIC or custom SoC. Optimized hardware that specifically implements our algorithm will always win in terms of speed and power - at a cost of vastly increased transistor count.
Imagination Technologies Tries to Make it Easier to Connect from Anything
Being out in the wild is supposed to get you away from things modern and technological. And yet… there are ways that new gadgetry might improve your isolated camping experience.
Let’s say, for example, that a critical camping information system would be useful. Perhaps it would link to a variety of on-line video channels dedicated to camping content. And, rather than packing yet another device, perhaps it could be integrated into an existing piece of camping equipment. Like, perhaps, your camp stove. It’s got a lid that flips up to block the wind – why not integrate a screen into it?
Moshe Gavrielov Gets His Zynq On and IBM Rolls Out a Graphene IC
In this week's Fish Fry, Amelia's special guest is Xilinx CEO Moshe Gavrielov who chats with her about their new Zynq embedded processing platform and how he sees this new addition not only changing the course of the Xilinx roadmap going forward but also where he thinks the FPGA industry is headed as a whole. Also this week, Amelia explores the new Graphene IC unveiled by IBM and checks out the Freescale/BMW collaboration that just might make parking our cars just a little bit easier.
And, in keeping with the Xilinx theme, you'll definitely want to get in on the competition for this week's awesome nerdy giveaway - a Spartan-6 LX9 MicroBoard, and as usual you'll need to tune in to find out how to win.
Winston Churchill once said that the United Kingdom and the United States are two nations divided by a single language. Sometimes it seems like that in an embedded development environment. In the green corner - the hardies. These are people who think in volts and transistors and will spend enormous effort to reduce watts burned by a system. In the red corner – the softies. Their thinking is dominated by efficient code execution time. The difference between the two is nicely encapsulated in the story of a UNIX based system that was burning excessive power: the processor never seemed to go into any form of standby mode. The hardies naturally blamed the softies, who in return disclaimed all responsibility and also pointed out it would be very hard to find a culprit in the vast number of lines of code in the system.
Averna’s Proligent Keeps Tabs and Makes Changes Where Needed
We in the semiconductor world live in a relatively self-contained environment. Processing is highly specialized, equipment is expensive and not really usable for anything else, and risks are high if something goes wrong.
So we tend to get a little, oh, inbred, with a few companies providing the variety of tools and services in a small-town supply chain.
Gary Smith, The Return of the Woz, and Other Fun Stuff
In this week's Fish Fry, Amelia dishes the dirt on this year's Design Automation Conference. She attempts to unravel the mysteries posed by Gary Smith in his annual EDA analysis, and re-hashes both the awesome and the uncomfortable moments of this year's Steve Wozinak keynote. Also this week, she gives some details on the history of the Design Automation Conference, why there don't seem to be as many attendees as in years past, and why it's so hard to navigate the show floor. Don't miss out on your chance to win a Lattice ECP3 Versa Development Kit. You'll just have to listen to find out how you can win it.
Complementary E-Beam Lithography
Brain surgery is a complicated process. After all, they don’t call it “brain surgery” for nothing. And it’s not a one-man show: it’s a team operation. Someone’s got to… ahem… mellow you out before taking you to the OR. Someone’s got to shave a bald spot. Someone’s got to make sure everything is clean and germ-free. Someone has to give you the final giggly-gas (or whatever will send you into an oblivious slumber). Someone has to provide… access to the brain. And then, finally, when everything else is ready, you bring in what those in show-biz would call the “talent.”
A Look at “Black Silicon”
There’s no such thing as “true black.” I mean, there’s the idea of it, the aspiration, but, so far, we have not been able to create a pure black in the real world. The bizarre realm of carbon nanotubage has gotten us close – very close – but still: it’s only close.
True black means that no light – nary a single photon – reflects off the surface. It’s all captured and absorbed. While this might have interesting artistic and philosophical ramifications, it also has a serious, practical impact. The good news is that, from this pragmatic standpoint, getting closer is still really good: we don’t need to be purists. (Philosophically, well, you’re on your own.)
Microchip’s new IDE, DAC Days And An App For Your Soul
In this week's Fish Fry, Amelia checks out some new intriguing iPhone apps including a DAC navigation app from Cadence, a couple new EE apps that might spark your fancy and even an app that will help you find inner peace (or at least that's what they claim). Also, she interviews Microchip Technology’s Development Tools Vice President Derek Carlson about their new IDE MPLABX and tries to figure out how their new software can help jump start your next project.
And remember to stay tuned for the nerdy giveaway this week...Amelia has sweetened the pot this week and she thinks you're going to like it.
