Next-Gen High-Speed Communication In Data Centers


Data centers are being flooded with data. While more of it needs to be processed locally, much of it also needs to be moved around within a system and between systems. This has put a spotlight on a variety of new optical technologies and methodologies. Yang Zhang, senior product marketing manager at Cadence, talks about the rapid increase in different types of optics and optical scenarios being... » read more

Real-World Applications Of Computational Fluid Dynamics


More powerful chips are enabling chips to process more data faster, but they're also having a revolutionary impact on how that data can be used. Simulations that used to take days or weeks now can be completed in a matter of hours, and multi-physics simulations that were implausible to even consider are now very much in the realm of what is possible. Parviz Moin, professor of mechanical enginee... » read more

Making Electronics More Efficient


Projections about the amount of energy required for AI in data centers and other electronic devices are putting a spotlight on more efficient electronics. But making chips and systems more efficient is an enormous challenge. It used to be as simple as turning down the voltage or moving to the next process node, but those approaches are no longer yielding the same kinds of benefits as in the pas... » read more

Challenges With Chiplets And Power Delivery


Chiplets hold the potential to deliver the same PPA benefits as an SoC, but with many more features and options that are possible on a reticle-constrained die. If chiplets live up to the hype, they will deliver what is essentially mass customization, democratizing and speeding the delivery of complex chips across a broad array of markets. Today, the focus has been on die-to-die interfaces, but ... » read more

New Issues In Power Semiconductors


The number of challenges is growing in power semiconductors, just as it is in traditional chips. Thermal dissipation and gradients, new design rules, and layout issues need to be considered, especially in the context of higher voltage and increased performance demands. Roland Jancke, design methodology head in Fraunhofer IIS’ Engineering of Adaptive Systems Division, talks about issues in int... » read more

Very Short Reach SerDes In Data Centers


Speed is critical inside of data centers, and the distance that signals have to travel can have a big impact on time to results. But there are a number of variables that need to be considered, including what is an acceptable loss, how much power can be dissipated in a server rack, and what are the various connection options being used. Keivan Javadi Khasraghi, staff technical product manager at... » read more

Issues In Calculating Glitch Power


The amount of power consumed by redundant non-functional toggles, or glitch power, can be as high as 35% of total power consumption in a design. What can be done about that? Godwin Maben, low-power architect and scientist at Synopsys, takes a deep dive into the causes of glitch, how it is affected by new process nodes and heterogeneous integration, and the impact of different workloads, higher ... » read more

Changes In Memory Design


An explosion of data in automotive, cloud, and AI are altering the fundamentals of memory design. One size no longer fits all, as memory is used for a broader set of applications, from automotive and cloud to consumer devices. Anand Theruvengadam, director of product management at Synopsys, talks about the impact of big data applications on density, memory stacking, and growing concerns about r... » read more

Impact Of Increased IC Performance On Memory


Increasing performance in advanced semiconductors is becoming more difficult as chips become more complex. There are more physical effects to contend with, different use cases, and challenges in making memory go faster. In addition, aging effects that once were ignored are now becoming critical concerns. Steven Woo, fellow and distinguished inventor at Rambus, talks about different factors that... » read more

Where Power Is Spent In HBM


HBM is gaining ground because of a spike in the amount of data that needs to be processed quickly, but big reductions in power are possible if that processing can be moved closer to the HBM modules, and if more can be done in each compute cycle without sending data back and forth to memory as frequently. Steven Woo, fellow and distinguished engineer at Rambus, talks about what can be done to bo... » read more
