Guarding Against Interlopers

As you approach the entrance, you know you’re in the right place. You almost feel it before you hear it. A few more steps and there remains no doubt. The unmistakable thump of some serious bass brings with it the promise of some serious hip-hop.

This club is much like any of a number of similar clubs you can find anywhere in any major metropolis. As with any musical event, the evening starts with the little-known people, the upstarts, those that feel they have something to say and need to prove that what they have … Read More → "Guarding Against Interlopers"

Counting the Cost of 2008

It’s been a funny old year, has 2008. Traditionally this is the time to pull your chair close to the fire, grab a glass of mulled wine and tell ghost stories. We won’t do that this year: no yarn we could spin would chill your bones half as effectively as the news about sub-prime mortgages, Ponzi schemes/scams, financial meltdowns, factory closures and Reductions in Force.

(Interestingly, a quick Google search show that the use of the term, Reduction in Force, seems to be mainly in press releases from North America. I suppose it … Read More → "Counting the Cost of 2008"

Auld Langxiety II

Should 2008 be forgot, and never brought to mind?  

Should global economic downturns be ignored, and days of auld lang syne?

A few years ago, in the United States, tax laws were passed that made it attractive to “flip” houses by buying them, fixing them up, and quickly selling them for a big profit – mostly tax-free profit.  Many Americans made substantial amounts of money by moving every year or two to a different residence and reaping the rewards.  Of course, all this rapid turnover and appreciation in the housing market pushed home prices … Read More → "Auld Langxiety II"

Layout-Aware Diagnosis of IC Failures

With increasing size and complexity of ICs and limitations in traditional physical failure analysis tools, failure analysis engineers need help determining the root cause of a specific failing die. Yield engineers, on the other hand, need to be able to identify systematic yield limiters that may be disguised as random failures caused by complex interactions between the manufacturing process and specific design patterns. A failure diagnosis tool that provides high accuracy and resolution, as well as meaningful defect classifications, can be of high value to both engineers’ jobs.Today, most complex ICs are tested using built-in scan test … Read More → "Layout-Aware Diagnosis of IC Failures"

And That Makes 1

A look outside confirms it. The sky ranges from dull white to steely dark gray. An occasional glimpse of blue is quickly corrected to bring it into conformance with the surrounding severity. The sound of the traffic is enhanced by the swish of tire on wet road. And it’s cold. By California standards, anyway… Yup, it’s winter. No, you don’t see this in the travel guides, but as the old year gives way to the new, Silicon Valley receives – hopefully – its annual drink of water from the skies, and would-be … Read More → "And That Makes 1"

Keeping Power Under Control

Nothing should be simpler than turning the power on and off. It’s just a switch. Switch it on; switch it off. Easy peasey. Right?

Well, not so fast. There ain’t just one power supply on a board anymore. These days you’ve gotta have in place a veritable cornucopia of power levels to satisfy all the finicky chips that are spreading like a bad mold across your boards. And the different power lines have different capacitances and different drivers, so that simply shutting the power down can conjure up images of leaves … Read More → "Keeping Power Under Control"

Verayo Leaves Tiny Fingerprints on Chips

How do penguins tell each other apart? For that matter, how to barnacles, or pigeons, or orangutans recognize each other (we know how dogs do it)? To our eyes, they all look pretty much the same.

The same could be said of FPGAs. Mass production is one of the hallmarks of the semiconductor industry, as identical chips stream off the production lines. Intel’s enormously successful manufacturing prowess revolves around the mantra, “copy exact.” Every Intel fab is just like every other Intel fab, and every chip is identical to every other chip. That& … Read More → "Verayo Leaves Tiny Fingerprints on Chips"

Disziplin Muß Sein*

Software development processes can vary dramatically. If you program only occasionally as a hobby, like me, then you dream up what you want to do and immediately start coding. Working units then randomly materialize and just as quickly disappear like quantum fluctuations. Moving into the more professional arena, if there is a process, it can vary from something light, agile, and extreme, where code is generated quickly and converges towards requirements using Brownian successive approximation, all the way to heavyweight rational processes with which you risk spending your entire career just reading the manual (understanding it would take even … Read More → "Disziplin Muß Sein*"
