Industry Standards For Chiplets And Their Role In Test
By Jeorge Hurtarte - 14 Jan, 2025 - Comments: 0

As the semiconductor industry increasingly moves to chiplets, 2.5D/3D packaging, and heterogeneous integration, there are significant new challenges for test. Leaders like Teradyne have the technologies necessary to respond and innovate, but to keep the industry running smoothly, we need effective collaboration, and that demands standardization.

Overview of Machine Learning Algorithms Used In Hardware Security (TU Delft)
By Technical Paper Link - 09 Apr, 2023 - Comments: 0

A new technical paper titled "A Survey on Machine Learning in Hardware Security" was published by researchers at TU Delft. Abstract "Hardware security is currently a very influential domain, where each year countless works are published concerning attacks against hardware and countermeasures. A significant number of them use machine learning, which is proven to be very effective in ... » read more

High-Quality Test And Embedded Analytics Are Vital For Secure SoCs
By Lee Harrison - 11 Jan, 2022 - Comments: 0

Applications like as smart cards and devices used in the defense industry require security to ensure that sensitive data is inaccessible to outside agents. This used to be a niche requirement met through custom solutions. However, now that automotive and cyber-physical systems are proliferating, the requirements around secure test and monitoring are becoming mainstream. The current best strateg... » read more

PCB And IC Technologies Meet In The Middle
By Bryon Moyer - 12 Oct, 2021 - Comments: 1

Surface-mount technology (SMT) is evolving far beyond its roots as a way of assembling packaged chips onto printed circuit boards without through-holes. It is now moving inside packages that will themselves be mounted on PCBs. But SMT for advanced packages isn’t the same as the SMT we’ve been used to. “Many systems include multiple ASICs, a lot of memory, and that's all integrated i... » read more

Managing Device Certificates Is Becoming Harder
By Bryon Moyer - 07 Jan, 2021 - Comments: 0

As the number of devices connected to the Internet balloons, certificate management is becoming more complex, more essential, and significantly harder to keep track of. There are many different certificates for many different purposes, not to mention certificates that are unique to each device. And the lifetimes of those certificates may vary, making it even tougher to keep operating certifi... » read more

Digital Test Bulks Up – Or Down
By Bryon Moyer - 08 Dec, 2020 - Comments: 2

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

Are FPGAs More Secure Than Processors?
By Bryon Moyer - 08 Oct, 2020 - Comments: 0

Security concerns often focus on software being executed on processors. But not all electronic functionality runs in software. FPGAs provide another way to do work, and they can be more secure than functions executed in software. FPGAs provide more control of hardware and are more opaque to attackers. In the case of embedded FPGAs, the designer is in complete control of the entire system. Th... » read more

Problems And Solutions In Analog Design
By Ann Mutschler - 05 Aug, 2020 - Comments: 1

Advanced chip design is becoming a great equalizer for analog and digital at each new node. Analog IP has more digital circuitry, and digital designs are more susceptible to kinds of noise and signal disruption that have plagued analog designs for years. This is making the design, test and packaging of SoCs much more complicated. Analog components cause the most chip production test failures... » read more

The Importance Of An eFPGA’s Configuration Interfaces
By Volkan Oktem - 02 Aug, 2018 - Comments: 0

eFPGAs are heralded throughout the semiconductor industry for their flexibility and programmability, especially when it comes to high-performance compute applications. Let’s take a closer look at how an eFPGA is configured. Each instance of the eFPGA in an ASIC or SoC design must be configured after the system powers up because this eFPGA employs nonvolatile SRAM technology to store its co... » read more
