SoC Power Grid Challenges


The consumption of power and dissipation of heat within large SoCs has received a lot of attention recently, but that is only part of the issue. Power also has to be reliably delivered onto and around the system. This is becoming increasingly difficult, and new nodes are adding to the list of challenges. "If we were building chips where there was only a single Vdd and Vss then it is not that... » read more

Implementation Limits Power Optimization


Implementation is still the step that makes or breaks power budgets in chip design, despite improvements in power estimation, power simulations, and an increase in the number of power-related architectural decisions. The reason: All of those decisions must be carried throughout the design flow. “If implementation decides to give up, then it doesn't really matter at the end of the day,” s... » read more

Executive Insight: Grant Pierce


Grant Pierce, president and CEO of Sonics, sat down with Semiconductor Engineering to discuss new ways to increase energy efficiency in SoCs. What follows are excerpts of that conversation. SE: Looking out at the semiconductor industry there are a lot of changes underway right now. What are the biggest impacts from your perspective? Pierce: The amount of data that is being captured or sen... » read more

Why IP Subsystems And Why Now?


At the recently concluded DAC 2016 conference in Austin, Texas, I had the opportunity to participate in a tutorial on IP Subsystems on Wednesday the 8th. Also participating were Marco Brambilla, Director of Engineering at Synapse Design and Drew Wingard, CTO at Sonics. The reality today is that device complexity in many applications has risen to levels that require increasing amounts of disc... » read more

Decoding The Brain


At the Design Automation Conference this year, Lou Scheffer, principal scientist for the Howard Hughes Medical Institute, gave a visionary talk entitled Learning from Life: Biologically Inspired Electronic Design. Scheffer is an IC design guy who came through Stanford and Caltech and worked for HP and [getentity id="22032" e_name="Cadence"] before switching to the medical field eight years a... » read more

Photonics Moves Closer To Chip


Silicon photonics is resurfacing after more than a decade in the shadows, driven by demands to move larger quantities of data faster, using extremely low power and with minimal heat. Until recently, much of the attention in photonics focused on moving data between servers and storage. Now there is growing interest at the PCB level and in heterogeneous multi-chip packages. Government, academi... » read more

Tech Talk: Power Reduction


Sonics CTO Drew Wingard talks about energy processing units, and how to utilize idling circuitry to save as much as 95% of the energy spent on specific processes. [youtube vid=IZy38BfHP60] » read more

Bridging the IP Divide


IP reuse enabled greater efficiency in the creation of large, complex SoCs, but even after 20 years there are few tools to bridge the divide between the IP provider and the IP user. The problem is that there is an implicit fuzzy contract describing how the IP should be used, what capabilities it provides, and the extent of the verification that has been performed. IP vendors have been trying to... » read more

Power-Centric Chip Architectures


As traditional scaling runs out of steam, new chip architectures are emerging with power as the starting point. While this trend has been unfolding for some time, it is getting an extra boost and sense of urgency as design teams weigh a growing number of design challenges and options across a variety of new markets. Among the options are [getkc id="196" kc_name="multi-patterning"] and [getkc... » read more

FinFET Scaling Reaches Thermal Limit


In 1974, Robert H. Dennard was working as an IBM researcher. He introduced the idea that MOSFETs would continue to work as voltage-controlled switches in conjunction with shrinking features, providing doping levels, the chip's geometry, and voltages are scaled along with those size reductions. This became known as Dennard's Law even though, just like Moore's Law, it was anything but a law. T... » read more
