Driver Update Disables Counterfeit Chips
It sounds like something out of a spy thriller. A piece of security software, masquerading as a routine driver update, sniffs out enemy chips and terminates them with extreme prejudice. There is no fix; the chip, and everything it’s connected to, is bricked.
Sneaky, huh? And not really all that hard to implement. With nearly everything connected “to the cloud,” it’s easy to insert new software remotely. And we’re all accustomed to downloading and installing new drivers every few weeks, so there’s nothing suspicious that would tip anyone off.
The case this week involves FTDI, a company that makes popular and inexpensive USB-interface chips. You’ve probably got one inside some device nearby, or you’ve used FTDI chips in your own designs.
Mentor Elevates PCB Game
For decades, the PCB design tools competition has been a board game. The scope of the problem was the design of a single PCB, and the competitors - Mentor, Cadence, Zuken, Altium/Protel, and the rest - all battled for supremacy with the scope, features, power, and cost of their solutions. The market for board tools actually got a little boring for years, with the major players competing mainly on cost and incumbency in the high-end (enterprise) level and in the low-cost (desktop) markets.
In the past few years, however, the battle has been heating up again. Demands on even “ordinary” board design have grown, as signal- and power-integrity became common problems with higher speed components, and IC packaging and mounting technology caused new challenges for layout. As a result, “desktop” tools began to inherit many of the features associated with “enterprise” tools. Enterprise design tool suites had to once again scramble to differentiate themselves and justify their significantly higher costs.
Or, How the Heck Do I Design a Photonic Circuit?
Several weeks ago we took a look at the expanding role of EDA. And then a couple weeks ago we delved into the bizarre world of silicon photonics. Yeah, we didn’t get too deep because the bottom drops off pretty quickly, and I’m not sure I could tread water credibly any deeper. But we got a flavor.
So now, we bring these two things together to answer the question, “If I’m going to be involved in a photonic chip design, what tools am I going to use?” OK, so if you’re an electronics designer, you’ll probably be asking the question, “What tools will the photonics pholks be using, and how will thier world interface to mine?”
Folks have been doing silicon photonics research for a long time now, and you need tools to do that. So it’s not like we’re just now seeing the emergence of new tools for this purpose. The thing is, there’s not a lot of profit in research, so the big guys that are commercially driven may not be attracted to such new endeavors in the early stages.
Carbon’s New Virtual Prototype Portal and UDG’s New Smart Robot
What’s the difference between a human and a pile of rocks? A robot algorithm (of course)! In this week’s episode of Fish Fry, we check out a new robot being developed at the University of Guadalajara that utilizes a pattern recognition algorithm to determine the silhouette of a human body. Also this week, we talk about the trials and tribulations of SoC design with Bill Neifert of Carbon Design Systems. Bill and I discuss Carbon's focus on the automatic creation of RTL-accurate models for integration into SoC designs and how you can make your IP configuration options a whole bunch easier.
Is Crowdfunding a Good Option For Your Million-Dollar Idea?
“More ideas are lost than found.” That was Maker Faire co-founder Dale Doughtery’s response to a reporter’s question about intellectual property concerns in the show-and-tell environment of the World Maker Faire (quoted in Kevin Morris’s terrific article about the faire). This simple statement seems especially true in the world of engineering. How many ideas for new projects, new start-up companies, and new inventions never make it out of their would-be inventor’s brain? The electrical engineering industry has probably produced millions of lost ideas. Some of these lost ideas may be better off never becoming a reality, but it’s almost certain that there are some truly brilliant or even genius ideas that never come to fruition.
Getting a new idea off the ground can be particularly difficult in this industry, where the inventions and innovations tend to be technical and complicated. Trying to find investors and funding for a project is no picnic for any inventor or innovator, but it can get especially tricky when you’re trying to explain complex electrical engineering concepts to, say, the panel on “Shark Tank.”
Rambus’s AES Crypto IP Resists DPA Attacks
“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke
You have got to be kidding me. I mean, I’m an engineer. I know how stuff works. And you’re telling me you can somehow snag my computer’s encryption keys out of thin air? No way. No. @%$#-ing. Way.
I’ve seen it happen. I didn’t believe it at first, but there’s nothing quite like a live demonstration to make you a convert. It’s time to stock up on tinfoil hats. Here’s the background: Practically every computer, cell phone, tablet, cable TV decoder, satellite box, smartcard, modern passport, or other gizmo uses encryption in some way.
