Designing For Multiple Die


Integrating multiple die or chiplets into a package is proving to be very different than putting them on the same die, where everything is developed at the same node using the same foundry process. As designs become more heterogeneous and disaggregated, they need to be modeled, properly floor-planned, verified, and debugged in the context of a system, rather than as individual components. Typi... » read more

RISC-V Pushes Into The Mainstream


RISC-V cores are beginning to show up in heterogeneous SoCs and packages, shifting from one-off standalone designs toward mainstream applications where they are used for everything from accelerators and extra processing cores to security applications. These changes are subtle but significant. They point to a growing acceptance that chips or chiplets based on an open-source instruction set ar... » read more

How The Electronics Industry Can Shape A More Sustainable, Energy-Efficient World


By Piyush Sancheti and Godwin Maben We’re already experiencing the effects of our world’s changing climate—devastating wildfires, prolonged droughts, torrential flooding, just to name a few examples. Global energy consumption is increasing, raising carbon dioxide levels and triggering extreme weather conditions. Two key forces driving these trends are the shift to hyperscale datacenter... » read more

Blog Review: Dec. 20


Synopsys' Twan Korthorst explains how PDKs can help accelerate the photonic IC design process by offering building blocks such as several types of waveguides, passive devices like splitters, combiners, and filters, along with active devices such as phase shifters, detectors, semiconductor optical amplifiers, and lasers. Siemens EDA's Harry Foster examines IC and ASIC design trends, including... » read more

Designing And Securing Chips For Outer Space


Design considerations for hardware used in space go far beyond radiation hardening. These devices have to perform flawlessly for years, under extreme temperature variations, and potentially banged up by space junk or other particles floating in the void over its projected lifetime. Reliability in space adds a whole different set of design considerations. For example, while it's unlikely anyo... » read more

The March Toward Chiplets


The days of monolithic chips developed at the most advanced process nodes are rapidly dwindling. Nearly everyone working at the leading edge of design is looking toward some type of advanced packaging using discrete heterogeneous components. The challenge now is how to shift the whole chip industry into this disaggregated model. It's going to take time, effort, as well as a substantial reali... » read more

3D-IC Reliability Degrades With Increasing Temperature


The reliability of 3D-IC designs is dependent upon the ability of engineering teams to control heat, which can significantly degrade performance and accelerate circuit aging. While heat has been problematic in semiconductor design since at least 28nm, it is much more challenging to deal with inside a 3D package, where electromigration can spread to multiple chips on multiple levels. “Be... » read more

Blog Review: Dec. 14


Siemens EDA's Harry Foster checks out design and verification language adoption trends in FPGA projects, including testbench methodologies and assertion languages. Cadence's Veena Parthan finds that giving electric vehicle batteries a second life as energy storage devices can extend their useful life by 5 to 8 years, but a lack of standardization in EV batteries poses challenges. Synopsys... » read more

Variability Becoming More Problematic, More Diverse


Process variability is becoming more problematic as transistor density increases, both in planar chips and in heterogeneous advanced packages. On the basis of sheer numbers, there are many more things that can wrong. “If you have a chip with 50 billion transistors, then there are 50 places where a one-in-a-billion event can happen,” said Rob Aitken, a Synopsys fellow. And if Intel’s... » read more

Week In Review: Manufacturing, Test


The more than 1,400 attendees at this week’s IEDM, which celebrated the 75th anniversary of the transistor, were clearly focused on making the next 75 years of semiconductors even more remarkable than the last. Intel, Samsung, TSMC, STMicroelectronics, GlobalFoundries and imec announced breakthrough devices, materials, and even integration approaches. These included: Intel showcased adva... » read more
