Interconnects In A Domain-Specific World


Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more

Breaking The 2nm Barrier


Chipmakers continue to make advancements with transistor technologies at the latest process nodes, but the interconnects within these structures are struggling to keep pace. The chip industry is working on several technologies to solve the interconnect bottleneck, but many of those solutions are still in R&D and may not appear for some time — possibly not until 2nm, which is expected t... » read more

Taming Non-Predictable Systems


How predictable are semiconductor systems? The industry aims to create predictable systems and yet when a carrot is dangled, offering the possibility of faster, cheaper, or some other gain, decision makers invariably decide that some degree of uncertainty is warranted. Understanding uncertainty is at least the first step to making informed decisions, but new tooling is required to assess the im... » read more

Emerging Apps And Challenges For Packaging


Advanced packaging is playing a bigger role and becoming a more viable option to develop new system-level chip designs, but it also presents chipmakers with a confusing array of options and sometimes a hefty price tag. Automotive, servers, smartphones and other systems have embraced advanced packaging in one form or another. For other applications, it's overkill, and a simpler commodity pack... » read more

Slower Metal Bogs Down SoC Performance


Metal interconnect delays are rising, offsetting some of the gains from faster transistors at each successive process node. Older architectures were born in a time when compute time was the limiter. But with interconnects increasingly viewed as the limiter on advanced nodes, there’s an opportunity to rethink how we build systems-on-chips (SoCs). ”Interconnect delay is a fundamental tr... » read more

Scramble For The White Space


Chipmakers are pushing to utilize more of the unused portion of a design for different functions, reducing margin in the rest of the chip to more clearly define that white space. White space typically is used to relieve back-end routing congestion before all of the silicon area is used up. But a significant amount of space still remain unused. That provides an opportunity for inserting monit... » read more

Sensor Fusion Challenges In Cars


The automotive industry is zeroing in on sensor fusion as the best option for dealing with the complexity and reliability needed for increasingly autonomous vehicles, setting the stage for yet another shift in how data from multiple devices is managed and utilized inside a vehicle. The move toward greater autonomy has proved significantly more complicated than anyone expected at first. There... » read more

Interconnects Emerge As Key Concern For Performance


Interconnects are becoming increasingly challenging to design, implement and test as the amount of data skyrockets and the ability to move that data through denser arrays of compute elements and memories becomes more difficult. The idea of an interconnect is rather simple, but ask two people what constitutes an interconnect and you're likely to get very different answers. Interconnects are e... » 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

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
