Electronics Supply-Chain Trust Standards Emerge


Creative new ideas for electronics supply-chain trust are in rich supply, whether securing identity, protecting logistics, or establishing provenance. But underlying these efforts are wide-ranging standards in development from a broad set of organizations. Today, no one-stop-shop for supply-chain standards exists. Instead, there is huge fragmentation. It can be difficult to identify all of t... » read more

Waking And Sleeping Create Current Transients


Silicon power-saving techniques are helping to reduce the power required by data centers and other high-intensity computing environments, but they’ve also added a significant challenge for design teams. As islands on high-powered chips go to sleep and wake up, the current requirements change quickly. This happens in a few microseconds, at most. The rapid change of loading creates a challen... » read more

Digital Test Bulks Up – Or Down


Large digital integrated circuits are becoming harder to test in a time- and cost-efficient manner. AI chips, in particular, have tiled architectures that are putting pressure on older testing strategies due to the volume of test vectors required. In some cases, these chips are so large that they exceed reticle size, requiring them to be stitched together. New testing efficiencies are needed... » read more

How Will Future Cars Interact With Humans?


Future automobiles may come with a set of controls very different from what we’re used to now. Mechanical knobs and switches already are being replaced by touchscreens, but that's just the beginning. There are a multitude of other possible ways in which drivers can interact with their vehicles, and the list is growing as technology drives down the cost of this new human-machine interface (... » read more

Blockchain Attempts To Secure The Supply Chain


Blockchain technology is starting to be deployed more widely In the battle against counterfeiting, often coupled with component IDs to allow device authentication. Securing the supply chain is a complex challenge, particularly as more IP from more vendors in more locations makes its way into chips, packages or even systems. Being able to attest to the history of the device to prove its prove... » read more

MPU Vs. MCU


There was a time when microprocessors and microcontrollers were distinct devices. There was never a question as to which one you were dealing with. But changes in the memory architecture have muddied the distinction in modern devices. There are a number of ways in which microprocessors and microcontrollers could possibly be differentiated. But there is no universal agreement as to how that s... » read more

Uniquely Identifying PCBs, Subassemblies, And Packaging


Securing the semiconductor supply chain is becoming much more difficult as devices increasingly are disaggregated, a shift being forced on the industry due to the rising cost of scaling and the need for more customization and faster time to market. Individual component IDs are an important starting point for supply chain trust, but they are no longer sufficient. Those components will end up ... » read more

Dealing With Sub-Threshold Variation


Chipmakers are pushing into sub-threshold operation in an effort to prolong battery life and reduce energy costs, adding a whole new set of challenges for design teams. While process and environmental variation long have been concerns for advanced silicon process nodes, most designs operate in the standard “super-threshold” regime. Sub-threshold designs, in contrast, have unique variatio... » read more

Does HW Vs. SW Choice Affect Quality And Reliability?


Electronic systems comprise both hardware and software. Which functions are implemented with hardware and which with software are decisions made based upon a wide variety of considerations, including concerns about quality and reliability. Hardware may intrinsically provide for higher device quality, but it is also the source of reliability concerns. This is in contrast with popular views of... » read more

New And Innovative Supply Chain Threats Emerging


The electronics supply chain is seeing evidence of increased sophistication in the counterfeiting of complex ICs and simple passives, both of which can impact the functioning and safety of the systems that use them. New technologies are being developed to build trust by helping to identify counterfeit devices before assembly and during failure analysis. It's too early to tell how effective t... » read more
