On-Chip Power Distribution Modeling Becomes Essential Below 7nm


Modeling power distribution in SoCs is becoming increasingly important at each new node and in 3D-ICs, where tolerances involving power are much tighter and any mistake can cause functional failures. At mature nodes, where there is more metal, power problems continue to be rare. But at advanced nodes, where chips are running at higher frequencies and still consuming the same or greater power... » read more

Solving Thermal Coupling Issues In Complex Chips


Rising chip and packaging complexity is causing a proportionate increase in thermal couplings, which can reduce performance, shorten the lifespan of chips, and impact overall reliability of chips and systems. Thermal coupling is essentially a junction between two devices, such as a chip and a package, or a transistor and a substrate, in which heat is transferred from one to the other. If not... » read more

Chip Design Shifts As Fundamental Laws Run Out Of Steam


Dennard scaling is gone, Amdahl's Law is reaching its limit, and Moore's Law is becoming difficult and expensive to follow, particularly as power and performance benefits diminish. And while none of that has reduced opportunities for much faster, lower-power chips, it has significantly shifted the dynamics for their design and manufacturing. Rather than just different process nodes and half ... » read more

Bespoke Silicon Rattles Chip Design Ecosystem


Bespoke silicon developers are shaking up relationships, priorities, and methodologies across the semiconductor industry, creating demand for skills that cross traditional boundaries, and driving new business models that leverage these enormous investments. Bespoke silicon designers today are a rare breed, capable of understanding the unique requirements of a specific domain, as well as a gr... » read more

Designing A Better Clock Network


Laying the proper clock network architecture foundation makes all the difference for the best performance, power, and timing of a chip, particularly in advanced node SoCs packed with billions of transistors. Each transistor, which acts like a standard cell, needs a clock. An efficient clock network should ensure the switching transistors save power. In today’s advanced nodes, when a design... » read more

EVs Raise Energy, Power, And Thermal IC Design Challenges


The transition to electric vehicles is putting pressure on power grids to produce more energy and on vehicles to use that energy much more efficiently, creating a gargantuan set of challenges that will affect every segment of the automotive world, the infrastructure that supports it, and the chips that are required to make all of this work. From a semiconductor standpoint, improvements in th... » read more

Strengthening The Global Semi Supply Chain


Within the semiconductor ecosystem, there are a number of dynamics pointing to the need for new ways of partnering in more meaningful ways that bring resiliency to the global semiconductor supply chain. One of these is the move to bespoke silicon, stemming from a shift in the companies that create most SoCs today -- the hyperscalar cloud providers. These market leaders know their workloads so w... » read more

New Data Management Challenges


An explosion in semiconductor design and manufacturing data, and the expanding use of chips in safety-critical and mission-critical applications, is prompting chipmakers to collect and manage that data more effectively in order to improve overall performance and reliability. This collection of data reveals a number of challenges with no simple solutions. Data may be siloed and inconsistent, ... » read more

Design For Security Now Essential For Chips, Systems


It's nearly impossible to create a completely secure chip or system, but much can be done to raise the level of confidence about that security. In the past, security was something of an afterthought, disconnected from the architecture and added late in the design cycle. But as chips are used increasingly in safety- and mission-critical systems, and as the value of data continues to rise, the... » read more

Challenges Grow For Modeling Auto Performance, Power


Rising complexity in automobiles is creating huge challenges about how to add more safety and comfort features and electronics into vehicles without reducing the overall range they can travel or pricing them so high that only the rich can afford them. While the current focus is on modeling hardware and software to understand interactions between systems, this remains a huge challenge. It req... » read more
