Retro Revolution

Retro is the new new.

Here in the age of ubiquitous high technology, styles and tastes have turned to the past. Vintage clothing, automobiles from yesteryear, pinup models, antique cocktails, and 60s home furnishings are all the rage with today’s hipsters. “Steampunks”, “Rockabillies”, and “Mods” crowd their respective club scenes. In the audio world, it’s vinyl albums, tube amplifiers, reel-to-reel tape, and horn speakers. Culturally-aware engineers who spend their days worrying about leakage current in 32nm transistors go home in the evening and crank the LP version of Louis Armstrong singing St. James Infirmary on … Read More → "Retro Revolution"

Reducing Test Time and Cost for an Advanced Wireless Device

Designing wireless infrastructure chips at 65 nm and below introduced subtle failure mechanisms previously unobserved at larger process nodes. These new failure mechanisms, along with the requirements for better self-test in the field and limitations on available IC pins to interface with automated testing equipment, have resulted in tougher test requirements at STMicroelectronics.

STMicroelectronics’ advanced designs must be of the highest quality for demanding end-product applications. We use in-system test to ensure the device is … Read More → "Reducing Test Time and Cost for an Advanced Wireless Device"

Using Power and Integrity in the Same Sentence

Power is seductive. It has attracted the attention of universities, designers, tool vendors, journalists, and anyone who wants to be anyone in the silicon and systems worlds. Of course, unlike the situation in so many hallowed halls around the world, the aim here is to reduce power, not increase it (or gather it for oneself). Out of the limelight, however, is the stability of the power infrastructure: how robust is a chip’s power grid in the face of potentially wild gyrations of power draw as a chip is put through its paces? This is the realm of … Read More → "Using Power and Integrity in the Same Sentence"

15 Billion Nodes, and 8 Bits

If you want to see the embedded industry out in force, forget San Jose and Boston – book a ticket to Nuremberg for the first week in March. This year numbers were slightly down on visitors (just under 16,000) but up on exhibitors – over 700 of them. And I think that this will be seen as the year in which the embedded world, more broadly, will be seen to have changed. One reason for this is 15 billion. Even in a period where governments and banks are lightly throwing trillions of dollars around, 15 billion … Read More → "15 Billion Nodes, and 8 Bits"

Superlative Soup

Many of us who wound up in engineering-related careers were fascinated with technology as kids. Whether we were reading about cars, airplanes, computers, or hi-fi gear, we were intrigued by the latest and greatest of whatever genre we were investigating. What was the fastest car – the biggest airplane – the most powerful sound system? The exotic and superlative held a special fascination, often manifest as posters hanging on our walls or as the topic of playground discussion. “Nuh-uh, the Lambo has a top speed of almost 200MPH – way faster than that lame-o Ferrari on your poster!” It& … Read More → "Superlative Soup"

Showing Your True Corners

A lot has been written about the increasing difficulty of optimizing a design as process dimensions have become increasingly minute. Not only is it harder to balance performance against area, but power must be considered as well. Managing yield is a constant struggle since it’s no longer a question of where to cut off a distribution tail: it’s a question of how to fix the distribution so that you don’t over- or under-design your product. Too sloppy and you lose a lot of yield; too rigid and you will chew up too much … Read More → "Showing Your True Corners"

Playing “What If…” With Multicore Processors

Multicore processors are upon us, but how much do they really help? If your boss were to ask you right now, “how much faster will our code run on a two-, four-, or eight-core processor” could you answer the question? How many of us have any idea how much performance we’d gain by moving from a single-core to a multicore processor?

Well, wonder no more. A Scottish prism is here to answer that very question.

“Prism” is the name of a new software-analysis tool from CriticalBlue, a Scottish company … Read More → "Playing “What If…” With Multicore Processors"

How Physical Synthesis Enables FPGA Design Productivity

As FPGAs increase in density, system designers are using these increased densities to the maximum by creating larger and more complex designs. These large designs are based on design requirements that either requires adding new functionality to an existing application such as a channel card or a line card used in wireless applications or reducing board real estate by combining the functionality of two chips into a single device or creating new designs for new applications.

These varied designs could contain … Read More → "How Physical Synthesis Enables FPGA Design Productivity"

GateRocket Blasts Off

The system is both elegant and enigmatic.

When visitors see the RocketDrive sitting on your lab bench (particularly if it is plugged into the handsome show-floor-worthy box currently making the rounds at trade shows), your “cool factor” will definitely creep up a notch or two. When you use it to help you knock bugs out of your next FPGA design, you’ll most likely be pleased with your purchase. GateRocket’s RocketDrive is a useful tool for FPGA designers.

You have to be careful, though, not to think about it too hard.

You … Read More → "GateRocket Blasts Off"

Emulate This!

When each chip you design is going to cost you millions in mask charges and other associated fees, and when any mistake in such a chip can cost you millions more, it makes sense that you’re willing to fork out some cash to help reduce the chances of a flub. And when getting to market sooner means dollars in your pocket, it’s likely that getting a chance to test your software earlier will also be worth some coin.

Of course, this is the whole reason anyone pays for good chip design tools (as opposed to … Read More → "Emulate This!"
