Moving Data And Computing Closer Together
By Bryon Moyer - 09 Jul, 2020 - Comments: 2

The speed of processors has increased to the point where they often are no longer the performance bottleneck for many systems. It's now about data access. Moving data around costs both time and power, and developers are looking for ways to reduce the distances that data has to move. That means bringing data and memory nearer to each other. “Hard drives didn't have enough data flow to cr... » read more

Building Fugaku, The World’s Fastest Supercomputer
By Satoshi Matsuoka - 09 Jul, 2020 - Comments: 1

My fascination with computers started back in 1976. I remember it well: I was in the 8th grade, and I’d just returned to Japan from a stint in the US. One day I found myself in Tokyo’s Akihabara area, otherwise known as ‘Electric Town.’ This place was and still is the tech heartbeat of Japan, bright and buzzing with all the latest gadgets. On this particular day, among the displays of ... » read more

Designing For Extreme Low Power
By Brian Bailey - 09 Jul, 2020 - Comments: 3

There are several techniques available for low power design, but whenever a nanowatt or picojoule matters, all available methods must be used. Some of the necessary techniques are different from those used for high-end designs. Others have been lost over time because their impact was considered too small, or not worth the additional design effort. But for devices that last a lifetime on a si... » read more

Power Impact At The Physical Layer Causes Downstream Effects
By Ann Mutschler - 09 Jul, 2020 - Comments: 0

Data movement is rapidly emerging as one of the top design challenges, and it is being complicated by new chip architectures and physical effects caused by increasing density at advanced nodes and in multi-chip systems. Until the introduction of the latest revs of high-bandwidth memory, as well as GDDR6, memory was considered the next big bottleneck. But other compute bottlenecks have been e... » read more

‘Speak No Evil’ And SoC Problems
By Tim Penhale-Jones - 09 Jul, 2020 - Comments: 0

In the first of this blog trilogy, 'Are you listening,' I looked at not waiting for hindsight to be wise after the event, instead make use of what’s available and act ahead of time. In the second, 'See no evil,' we bizarrely saw how Sir Francis Drake, Admiral Nelson and Clint Eastwood all had something in common with Mizaru, one of the 3 wise monkeys (Kikazaru and Iwazaru being the other two)... » read more

Simulation Of Semiconductor Edge-Emitting Lasers
By Peter Hallschmid - 09 Jul, 2020 - Comments: 0

By Peter Hallschmid and Dylan McGuire The demand for photonics technology continues to grow with popular laser applications including semiconductor optical amplifiers (SOAs), Fabry-Perot (FP) devices and distributed feedback (DFB) lasers. The next episode of Ansys’ photonics webinar series outlines the latest Ansys Lumerical flows and products for simulating and generating compact mod... » read more

Fused: Closed-Loop Performance And Energy Simulation Of Embedded Systems
By Arm - 08 Jul, 2020 - Comments: 0

Energy-driven computing is an emerging paradigm that aims to fuel the proliferation of tiny and low-cost IoT sensing and monitoring devices. Energy-driven computers are generally powered by energy harvesting sources, and adapt their operation at runtime according to energy availability; thus, they must be designed and tested according to the expected dynamics of their power source. However, tod... » read more

Fast And Accurate Variation-Aware Mixed-Signal Verification Of Time-Domain 2-Step ADC
By Mentor, a Siemens Business - 08 Jul, 2020 - Comments: 0

To meet today’s analog-to-digital converter (ADC) specifications and to produce a high-yield design, teams typically need to perform extensive brute force mixed-signal simulations to account for all potential design variation. However, at nanometer nodes, the number of process, voltage and temperature (PVT) corners and parametric variation grow exponentially making the simulation impractical ... » read more

The Implementation Of Embedded In-Chip Sensing Fabrics In Today’s Cutting-Edge Technologies
By Moortec - 08 Jul, 2020 - Comments: 0

This whitepaper takes a comprehensive look at the implementation of Embedded Sensing Fabrics in today’s cutting-edge technologies and how this can benefit today’s advanced node semiconductor design engineers by improving the performance and reliability of SoC designs. With advances in CMOS technology, and the scaling of transistor channel lengths to nanometer (nm) dimensions, the density of... » read more

Blog Review: July 8
By Jesse Allen - 08 Jul, 2020 - Comments: 0

Cadence's Paul McLellan profiles Alessandra Nardi, recipient of this year's Marie R. Pistilli Women in EDA award, how she entered the industry and her latest work on automotive and a functional safety language. In a video, Mentor's Colin Walls checks out why RISC-V is the hot new fashion in embedded systems development. A Synopsys writer explains why the MACsec security protocol is so imp... » read more
