NoCs In 3D Space


A network on chip (NoC) has become an essential piece of technology that enables the complexity of chips to keep growing, but when designs go 3D, or when third-party chiplets become pervasive, it's not clear how NoCs will evolve or what the impact will be on chiplet architectures. A NoC enables data to move between heterogeneous computing elements, while at the same time minimizing the resou... » read more

What’s Missing In 2.5D EDA Tools


Gaps in EDA tool chains for 2.5D designs are limiting the adoption of this advanced packaging approach, which so far has been largely confined to high-performance computing. But as the rest of the chip industry begins migrating toward advanced packaging and chiplets, the EDA industry is starting to change direction. There are learning periods with all new technologies, and 2.5D advanced pack... » read more

Interconnects Essential To Heterogeneous Integration


Designing and manufacturing interconnects is becoming more complex, and more critical to device reliability, as the chip industry shifts from monolithic planar dies to collections of chips and chiplets in a package. What was once as simple as laying down a copper trace has evolved into tens of thousands of microbumps, hybrid bonds, through-silicon vias (TSVs), and even junctions for optical ... » read more

UCIe-3D: SiP Architectures With Advanced 3D Packaging With Shrinking Bump Pitches (Intel)


A technical paper titled “High-performance, power-efficient three-dimensional system-in-package designs with universal chiplet interconnect express” was published by researchers at Intel. Abstract: "Universal chiplet interconnect express (UCIe) is an open industry standard interconnect for a chiplet ecosystem in which chiplets from multiple suppliers can be packaged together. The UCIe 1.0... » read more

Accellera Preps New Standard For Clock-Domain Crossing


Part of the hierarchical development flow is about to get a lot simpler, thanks to a new standard being created by Accellera. What is less clear is how long will it take before users see any benefit. At the register transfer level (RTL), when a data signal passes between two flip flops, it initially is assumed that clocks are perfect. After clock-tree synthesis and place-and-route are perfor... » read more

Integration Challenges For RISC-V Designs


One of the big draws of RISC-V is that it allows design teams to create unique chips or chiplets and to make modifications to the instruction-set architecture. That extra degree of freedom also creates some issues when it comes to integrating those designs into packages or systems because they may require non-standard connectivity approaches. Frank Schirrmeister, vice president of marketing at ... » read more

UCIe Goes Back To The Drawing Board


The integration of multiple dies within a single package increasingly is viewed as the next evolution for extending Moore’s Law, but it also presents myriad challenges — particularly in achieving a universally accepted standard integrating plug-and-play chiplets from different vendors. “In some respects, people are already doing this,” says Debendra Das Sharma, Intel senior fellow an... » read more

Why Chiplets Are So Critical In Automotive


Chiplets are gaining renewed attention in the automotive market, where increasing electrification and intense competition are forcing companies to accelerate their design and production schedules. Electrification has lit a fire under some of the biggest and best-known carmakers, which are struggling to remain competitive in the face of very short market windows and constantly changing requir... » read more

IC Package Physical Design Best Practices


Historically IC package design has been a relatively simple task which allowed the die bumps to be fanned out on a package substrate to a floorplan geometry suitable for connecting to a printed circuit board (PCB). But today the industry is moving to disaggregation of traditional monolithic SoC functions into chiplets often interfaced with local high-speed memory to avoid silicon reticle limits... » read more

Rethinking Memory


Experts at the Table: Semiconductor Engineering sat down to talk about the path forward for memory in increasingly heterogeneous systems, with Frank Ferro, group director, product management at Cadence; Steven Woo, fellow and distinguished inventor at Rambus; Jongsin Yun, memory technologist at Siemens EDA; Randy White, memory solutions program manager at Keysight; and Frank Schirrmeister, vice... » read more
