Quantum Shifts


By Ed Sperling Intel, STMicroelectronics and some of the leading memory providers already are working on 10nm process technology, and advanced researchers in universities and industry-leading companies are looking at 7nm, 5nm and even beyond. Those who have glimpsed this technological future have similar observations. There is no single technology problem that has to be solved at these node... » read more

Moore’s Law Revisited


It’s no surprise that Moore’s Law can continue for many more generations. Intel’s road map already extends down to 5nm, most likely with carbon nanotube FETs, tunnel FETs, graphene TSVs and maybe even fully depleted SOI to replace bulk CMOS. The rest of the industry has been hanging back a node or two, gliding on the coattails of what Intel and companies like IBM, Samsung and STMicroel... » read more

Thanks For The Memories


By Ed Sperling The amount of real estate in a design now devoted to memories—SRAM on chip, DRAM off chip, and a few other more exotic options showing up occasionally—is a testament to the amount of data that needs to be utilized quickly in both mobile and fixed devices. Memory is almost singlehandedly responsible for the routing congestion now plaguing complex SoCs. It is one of the mai... » read more

Where Does It Hurt?


By Ed Sperling The IC design industry is feeling a new kind of pain—this one driven by uncertainty over architectural shifts, new ecosystem interactions and new ways to account for costs. As mainstream ICs move from 50/45/40nm to around 32/28/22nm, there are only two choices for design teams—continue shrinking features or stack dies. In many cases, the ultimate solution may be a combina... » read more

The Good And Bad Of Models


By Ann Steffora Mutschler Driven by fierce competition and the fact that socket decisions are made long before silicon is manufactured, semiconductor companies today ship models and virtual prototypes to their OEMs very early in hopes of locking in the socket. Admittedly, this has been happening for some time, but due to complexity and the need for flexibility of models and virtual platf... » read more

Quiet, Steady And Sometimes Unexpected Advances For SOI


By Ed Sperling After years of talking about equivalent pricing, technical advantages and consistent processes, silicon on insulator finally appears to be making significant inroads—but not necessarily in ways, places, or even at process nodes where it initially was predicted to gain ground. What’s driving at least some of this change is the semiconductor industry’s progression toward ... » read more

Inflection Points Ahead


By Ed Sperling Engineering challenges have existed at every process node in semiconductor designs, but at 20nm and beyond, engineers and executives on all sides of the industry are talking about inflection points. An inflection point is literally the place where a curve on a graph turns down or up, but in the semiconductor industry it’s usually associated with the point at which a progres... » read more

Dealing With Test More Effectively


By Ed Sperling Shrinking geometries are starting to have the same effect on test as they are on other parts of an SoC, with the focus shifting from area to leakage, heat, noise, signal integrity, and the impact on overall system performance. The warning that design teams have to consider test much earlier in the design was issued to chipmakers years ago and largely ignored. At 28nm that war... » read more

Being Different Is Bad


By Ann Steffora Mutschler Today’s SoCs contain as much as 80% existing IP that either has been re-used from previous projects or obtained from a third party. Models are created of this hardware IP, as well as new portions of the design, in order to create a virtual prototype that allows the engineering team to see the complete system by running software and applications. While this a... » read more

Experts At The Table: Coherency


System-Level Design sat down to discuss coherency with Mirit Fromovich, principal solutions engineer at Cadence; Drew Wingard, CTO of Sonics; Mike Gianfagna, vice president of marketing at Atrenta, and Marcello Coppola, technical director at STMicroelectronics. What follow are excerpts of that conversation. SLD: We’ve been hearing a lot about Wide I/O. Why is it so important and what effec... » read more
