Is UCIe Really Universal?


Chiplets are rapidly becoming the means to overcome the slowing of Moore's Law, but whether one interface is capable of joining them all together isn't clear yet. The Universal Chiplet Interconnect Express (UCIe) believes it will work, but some in the industry remain unconvinced. At least part of the problem is that interconnect standards are never truly finished. Even today, the protocols tha... » read more

The Drive Toward Virtual Prototypes


Chipmakers are piling an increasing set of demands on virtual prototypes that go well beyond its original scope, forcing EDA companies to significantly rethink models, abstractions, interfaces, view orthogonality, and flows. The virtual prototype has been around for at least 20 years, but its role has been limited. It has largely been used as an integration and analysis platform for models t... » read more

Balancing Power And Heat In Advanced Chip Designs


Power and heat use to be someone else's problem. That's no longer the case, and the issues are spreading as more designs migrate to more advanced process nodes and different types of advanced packaging. There are a number of reasons for this shift. To begin with, there are shrinking wire diameters, thinner dielectrics, and thinner substrates. The scaling of wires requires more energy to driv... » 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 Redefines Custom ASICs


Semiconductor Engineering sat down to discuss bespoke silicon and what's driving that customization with Kam Kittrell, vice president of product management in the Digital & Signoff group at Cadence; Rupert Baines, chief marketing officer at Codasip; Kevin McDermott, vice president of marketing at Imperas; Mo Faisal, CEO of Movellus; Ankur Gupta, vice president and general manager of Siemens... » read more

Heterogenous Integration Creating New IP Opportunities


The design IP market has long been known for constant change and evolution, but the industry trend toward heterogenous integration and chiplets is creating some new challenges and opportunities. Companies wanting to stake out a claim in this area have to be nimble, because there will be many potential standards introduced, and they are likely to change quickly as the industry explores what is r... » read more

Why Hardware-Dependent Software Is So Critical


Hardware and software are two sides of the same coin, but they often live in different worlds. In the past, hardware and software rarely were designed together, and many companies and products failed because the total solution was unable to deliver. The big question is whether the industry has learned anything since then. At the very least, there is widespread recognition that hardware-depen... » read more

Wafer Shortage Improvement In Sight For 300mm, But Not 200mm


The supply chain for bare wafers is off-kilter. Demand is appreciably higher than the wafer suppliers can keep up with, creating shortages that could last for years. For 300mm starting wafers, the top five big players — SEH and Sumco of Japan, Siltronic of Germany, GlobalWafers of Taiwan, and SK Siltron of Korea — finally took action over the last year, spending billions on new wafer fac... » read more

Data Center Architectures In Flux


Data center architectures are becoming increasingly customized and heterogeneous, shifting from processors made by a single vendor to a mix of processors and accelerators made by multiple vendors — including system companies' own design teams. Hyperscaler data centers have been migrating toward increasingly heterogeneous architectures for the past half decade or so, spurred by the rising c... » read more

Why RISC-V Is Succeeding


There is no disputing the excitement surround the introduction of the RISC-V processor architecture. Yet while many have called it a harbinger of a much broader open-source hardware movement, the reasons behind its success are not obvious, and the implications for an expansion of more open-source cores is far from certain. “The adoption of RISC-V as the preferred architecture for many sili... » read more
