Modeling On-Chip Variation At 10/7nm


Simulation, a workhorse tool for semiconductor design, is running out of steam at 10/7nm. It is falling behind on chips with huge gate counts and an enormous number of possible interactions between all the different functions that are being crammed onto a die. At simulation's root is some form of SPICE, which has served as its underpinnings ever since SPICE was first published 44 years ago. ... » read more

Transient Power Problems Rising


Transient power is becoming much more problematic at 10/7nm, adding yet another level of complexity for design teams already wrestling with power issues caused by leakage, a variety of power management techniques to control dynamic power, and leakage current. At each new node there is less headroom for engineering teams to address these problems, and more likelihood that what they do in one ... » read more

Safety Plus Security: A New Challenge


Nobody has ever integrated safety or security features into their design just because they felt like it. Usually, successive high-profile attacks are needed to even get an industry's attention. And after that, it's not always clear how to best implement solutions or what the tradeoffs are between cost, performance, and risk versus benefit. Putting safety and security in the same basket is a ... » read more

Hardware/Software Tipping Point


It doesn't matter if you believe [getkc id="74" comment="Moore's Law"] has ended or is just slowing down. It is becoming very clear that design in the future will be significant different than it is today. Moore's law allowed the semiconductor industry to reuse design blocks from previous designs, and these were helped along by a new technology node—even if it was a sub-optimal solution. I... » read more

Maintaining Power Profiles At 10/7nm


Understanding power consumption in detail is now a must-have of electronic design at 10nm and below, putting more pressure on SoC verification to ensure a device not only works, but meets the power budget. As part of this, the complete system must be run in a realistic manner — at the system-level — when the design and verification teams are looking at the effects of power during hardwar... » read more

Power Challenges At 10nm And Below


Current density is becoming much more problematic at 10nm and beyond, increasing the amount of power management that needs to be incorporated into each chip and boosting both design costs and time to market. Current per unit of area has been rising since 90nm, forcing design teams to leverage a number of power-related strategies such as [getkc id="143" kc_name="dynamic voltage and frequency... » read more

Closing The Loop On Power Optimization


[getkc id="108" kc_name="Power"] has become a significant limiter for the capabilities of a chip at finer geometries, and making sure that performance is maximized for a given amount of power is becoming a critical design issue. But that is easier said than done, and the tools and methodologies to overcome the limitations of power are still in the early definition stages. The problem spans a... » read more

Analog’s Unfair Disadvantage


We live in an analog world, and yet digital has become the technology of choice. Mixed-signal solutions that used to contain significant amounts of analog, with just a small amount of digital signal processing, have migrated into systems where the analog to digital conversion happens at the very first opportunity. There are several reasons for this, and some of them build upon themselves. [g... » read more

Cloud Computing Chips Changing


An explosion in cloud services is making chip design for the server market more challenging, more diverse, and much more competitive. Unlike datacenter number crunching of the past, the cloud addresses a broad range of applications and data types. So while a server chip architecture may work well for one application, it may not be the optimal choice for another. And the more those tasks beco... » read more

The Hunt For A Low-Power PHY


Physics has been on the side of chipmakers throughout most of the lifetime of [getkc id="74" comment="Moore's Law"], but when dealing with the world outside the chip, physics is working against them. Pushing data at ever-faster rates through boards and systems consumes increasing amounts of power, but the power budget for chips has not been increasing. Could chips be constrained by their int... » read more
