When the Chips are Down, How Do You Know They Work? Design How-To 1/29/2004 Post a comment Today's VLSI design companies are all trying to grab a big slice of the pie when it comes to the complex chip designs of tomorrow. Getting a piece of the action is greatbut these companies have to understand that a complex design, no matter how cool, won't make it to silicon unless the company can verify its designbeyond the faintest doubt. And, judging by results, it is not certain that this is, in fact, the case, with headline examples of re-spin and over-run clear in the mind.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
