Where Timing And Voltage Intersect


João Geada, chief technologist at ANSYS, talks about the limitations for power delivery networks and what processors can handle, why the current solutions to these issues are causing failures, and how voltage reduction can affect timing. » read more

Thinking About AI Power In Parallel


Most AI chips being developed today run highly parallel series of multiply/accumulate (MAC) operations. More processors and accelerators equate to better performance. This is why it's not uncommon to see chipmakers stitching together multiple die that are larger than a single reticle. It's also one of the reasons so much attention is being paid to moving to the next process node. It's not ne... » read more

Changes In AI SoCs


Kurt Shuler, vice president of marketing at ArterisIP, talks about the tradeoffs in AI SoCs, which range from power and performance to flexibility, depending on whether processing elements are highly specific or more general, and the need for more modeling of both hardware and software together. » read more

Blog Review: Feb. 12


Complexity is growing by process node, by end application, and in each design. The latest crop of blogs points to just how many dependencies and uncertainties exist today, and what the entire supply chain is doing about them. Mentor's Shivani Joshi digs into various types of constraints in PCBs. Cadence's Neelabh Singh examines the complexities of verifying a lane adapter state machine in... » read more

Making Light More Reliable


The buzz around photonics in packages and between packages is growing. Now the question is whether it will work as expected, and where it will be useful. Replacing electrical with optical signals has been on the technology horizon for some time. Light moves faster through fiber than electrons through copper. How much faster depends upon the diameter of the wires, the substrate and interconne... » read more

Failure Analysis Becoming Critical To Reliability


Failure analysis is rapidly becoming a complex, costly and increasingly time-consuming must-do task as demand rises for reliability across a growing range of devices used in markets ranging from automotive to 5G. From the beginning, failure analysis has been about finding out what went wrong in semiconductor design and manufacturing. Different approaches, tools and equipment have improved ov... » read more

Software In Inference Accelerators


Geoff Tate, CEO of Flex Logix, talks about the importance of hardware-software co-design for inference accelerators, how that affects performance and power, and what new approaches chipmakers are taking to bring AI chips to market. » read more

Millimeter Wave: A Bridge Too Far?


5G is here. It already is available in new mobile phones, and the infrastructure for extremely fast cellular communication is being built out at a rapid pace. The big question now is which parts of this technology will be successful, and there still is no consistency in those predictions. 5G comes in two flavors, sub-6 GHz and millimeter wave, and the sub-6 GHz version offers immediate perfo... » read more

Hardware Attack Surface Widening


An expanding attack surface in hardware, coupled with increasing complexity inside and outside of chips, is making it far more difficult to secure systems against a variety of new and existing types of attacks. Security experts have been warning about the growing threat for some time, but it is being made worse by the need to gather data from more places and to process it with AI/ML/DL. So e... » read more

Bigger, Faster, More Diverse And Expensive


Aart de Geus, chairman and co-CEO of Synopsys, sat down with Semiconductor Engineering to talk about the race toward AI everywhere, how splintering markets are affecting design, and why software is now such a critical component of hardware development. SE: We're seeing big advances in compute performance due to advanced packaging and heterogeneous architectures. Is that sustainable? de Ge... » read more
