VCSEL Technology Takes Off


By Kevin Fogarty and Ed Sperling Vertical cavity surface emitting laser (VCSEL) technology, a proven but mostly niche technology until recently, is suddenly a very hot commodity thanks to the introduction of facial recognition in phones and other mobile devices. VCELS primarily have been used as a low-cost way of tracking movement and transfering data in computer mice, laser printers and ... » read more

Issues In Designing 5G Beamforming Antennas


As 5G networking inches closer to reality, one of the more stubborn problems also will be one of the smallest. Several issues have yet to be cracked with beamforming and massive MIMO antennas, which will make millimeter wave (mmWave) spectrum—a key ingredient in 5G networks—work on multiple devices and base-station locations. Millimeter wave is problematic yet promising. Between bands 30... » read more

Testing AI Systems


AI is booming. It's coming to a device near you—maybe even inside of you. And AI will be used to design, manufacture and even ship those devices, regardless of what they are, where they are used, or how they are transported. The big questions now are whether these systems work, for how long—and what do those metrics even mean? An AI system, or AI-enhanced system, is supposed to adapt ove... » read more

Using a Fault Insertion and Current Sensing Unit


When testing embedded software on mission critical electronic control units, like those used in automobiles or aircraft, it is important to validate the behavior with external faults for example if the integrity of the signals to the controller are compromised. The SLSC-12251/2 products from NI are designed for this purpose, these modules can be inserted into the signal path between the data ac... » read more

Making Autonomous Vehicles Safer


While self-driving vehicles are beta-tested on some public roads in real traffic situations, the semiconductor and automotive industries are still getting a grip on how to test and verify that vehicle electronics systems work as expected. Testing can be high stakes, especially when done in public. Some of the predictions about how humans will interact with autonomous vehicles (AVs) on public... » read more

AI In Chip Manufacturing


Ira Leventhal, New Concept Product Initiative vice president at Advantest, talks with Semiconductor Engineering about using analysis and deep learning to make test more efficient and more effective. https://youtu.be/3VVG4JVnjHo » read more

4 Issues In Test


When most design engineers think about test, they envision a large piece of equipment in the fab they probably will never actually see or interact with. But as chips become more complex—driven by an explosion in both quantity and different types of data—test is emerging as one of the big challenges in design and manufacturing. There are four primary segments for test, each with its own s... » read more

Making Sure A Heterogeneous Design Will Work


An explosion of various types of processors and localized memories on a chip or in a package is making it much more difficult to verify and test these devices, and to sign off with confidence. In addition to timing and clock domain crossing issues, which are becoming much more difficult to deal with in complex chips, some of the new devices are including AI, machine learning or deep learning... » read more
