Optimizing Power Supply


Any electrical engineer knows providing power to your board is a key feature in PCB design. While most boards can be functional, their true quality shines when the perfect level of power to components is achieved. Building and designing better power supplies is the best way to ensure the end-product has full life-cycle potential. But how do we ensure we can convert a (potentially variable) i... » read more

Von Neumann Upset


My recent article about the von Neumann architecture received some quite passionate responses, including one that thought I was attempting to slight the person. That was most certainly not the intent, given that the invention enabled a period of very rapid advancement in computers and technology in general. The process of invention and engineering are both quite similar and yet different. In... » read more

Testing More To Boost Profits


Not all chips measure up to spec, but as more data becomes available and the cost of these devices continues to rise, there is increasing momentum to salvage and re-purpose chips for other applications and markets. Performance-based binning is as old as color-banded resistors, but the practice is spreading — even for the most advanced nodes and packages. Over the last three decades, engine... » read more

Why It’s So Hard To Stop Cyber Attacks On ICs


Semiconductor Engineering sat down to discuss security risks across multiple market segments with Helena Handschuh, security technologies fellow at Rambus; Mike Borza, principal security technologist for the Solutions Group at Synopsys; Steve Carlson, director of aerospace and defense solutions at Cadence; Alric Althoff, senior hardware security engineer at Tortuga Logic; and Joe Kiniry, princi... » read more

Chip-Package Co-Analysis Using Ansys RedHawk-CPA


Ansys RedHawk-CPA is an integrated chip–package co-analysis solution that enables quick and accurate modeling of the package layout for inclusion in on-chip power integrity simulations using Ansys RedHawk. With RedHawk-CPA a designer can perform static IR drop analysis and AC hotspot analysis of the package layout following RedHawk static and dynamic analyses respectively. To ensure a reliab... » read more

Searching For Power Bugs


How much power is your design meant to consume while performing a particular function? For many designs, getting this right may separate success from failure, but knowing that right number is not as easy as it sounds. Significant gaps remain between what power analysis may predict and what silicon consumes. As fast as known gaps are closed, new challenges and demands are being placed on the ... » read more

Custom Designs, Custom Problems


Semiconductor Engineering sat down to discuss power optimization with Oliver King, CTO at Moortec; João Geada, chief technologist at Ansys; Dino Toffolon, senior vice president of engineering at Synopsys; Bryan Bowyer, director of engineering at Mentor, a Siemens Business; Kiran Burli, senior director of marketing for Arm's Physical Design Group; Kam Kittrell, senior product management group d... » read more

AI Inference Acceleration


Geoff Tate, CEO of Flex Logix, talks about considerations in choosing an AI inference accelerator, how that fits in with other processing elements on a chip, what tradeoffs are involved with reducing latency, and what considerations are the most important. » read more

Optimizing For Energy In Physical Design


Energy is a precious resource, which should not be wasted. Energy drives economies and sustains societies. Predictions show that the energy of electronics may soon consume 20% to 33% of the global energy supply, as it is highlighted in this blog post about "Design and Manufacturing in 2030" from Greg Yeric, fellow at Arm. Energy efficiency is such an important global issue that it is ... » read more

Managing Worst Case Power Conditions


With each new technology node, especially FinFET, the dynamic conditions within a chip are changing and becoming more complex in terms of process speeds, thermal activity and supply variation. Dennard scaling brought about the ability for power to be scaled down with each successive node so that power per unit area stayed roughly constant. However, as highlighted by John Hennessy at last y... » read more
