Sensors Will Proliferate In SoCs


No one likes being put on the spot, and yet we all like a forecast…and as we all know, the only guarantee with a forecast is that it is wrong. Sports commentators have carved out a special niche for themselves with the ‘commentators curse:’ just as they extol the virtues of an individual or a team, the sporting gods prove them wrong in spectacular fashion! Governments are no better: econo... » read more

Confusion Grows Over Packaging And Scaling


The push toward both multi-chip packaging and continued scaling of digital logic is creating confusion about how to classify designs, what design tools work best, and how to best improve productivity and meet design objectives. While the goals of design teams remains the same — better performance, lower power, lower cost — the choices often involve tradeoffs between design budgets and ho... » read more

System-Level Packaging Tradeoffs


Leading-edge applications such as artificial intelligence, machine learning, automotive, and 5G, all require high bandwidth, higher performance, lower power and lower latency. They also need to do this for the same or less money. The solution may be disaggregating the SoC onto multiple die in a package, bringing memory closer to processing elements and delivering faster turnaround time. But ... » read more

New Architectures, Much Faster Chips


The chip industry is making progress in multiple physical dimensions and with multiple architectural approaches, setting the stage for huge performance increases based on more modular and heterogeneous designs, new advanced packaging options, and continued scaling of digital logic for at least a couple more process nodes. A number of these changes have been discussed in recent conferences. I... » read more

Moore’s Law Enters The 4th Dimension


The basic idea that more transistors are better hasn't changed in more than half a century. In fact, the overriding theme of a number of semiconductor conferences this month is that we will never have enough compute capability or storage capacity. In the past, when the number of transistors in a given area actually did double every 18 to 24 months, increasing density per square millimeter fo... » read more

Chiplet Reliability Challenges Ahead


Assembling chips using LEGO-like hard IP is finally beginning to take root, more than two decades after it was first proposed, holding the promise of faster time to market with predictable results and higher yield. But as these systems of chips begin showing up in mission-critical and safety-critical applications, ensuring reliability is proving to be stubbornly difficult. The main driver fo... » read more

Better Security, Lower Cost


For years, chipmakers have marginalized security in chips, relying instead on software solutions. Eventually that approach caught up with them, creating near panic in a scramble to plug weaknesses involving speculative execution and branch prediction, as well as the ability to read the data from chips with commercially available tools such as optical probes. There were several reasons for th... » read more

Rethinking Competitive One Upmanship Among Foundries


The winner in the foundry business used to be determined by who got to the most advanced process node first. For the most part that benchmark no longer works. Unlike in the past, when all of the foundries and IDMs competed using basically the same process, each foundry has gone its own route. This is primarily due to the divergence of end markets, and the realization that as costs increase, ... » read more

Smaller Nodes, Much Bigger Problems


João Geada, chief technologist at Ansys, sat down with Semiconductor Engineering to talk about device scaling, advanced packaging, increasing complexity and the growing role of AI. What follows are excerpts of that conversation. SE: We've been pushing along Moore's Law for roughly a half-century. What sorts of problems are you seeing now that you didn't see a couple nodes ago? Geada: The... » read more

Power Impact At The Physical Layer Causes Downstream Effects


Data movement is rapidly emerging as one of the top design challenges, and it is being complicated by new chip architectures and physical effects caused by increasing density at advanced nodes and in multi-chip systems. Until the introduction of the latest revs of high-bandwidth memory, as well as GDDR6, memory was considered the next big bottleneck. But other compute bottlenecks have been e... » read more
