Test More Complex For Cars, IoT
By Ann Mutschler - 15 Feb, 2017 - Comments: 0

With increasing focus on safety-critical semiconductors—driven by ADAS, IoT, and security—functional safety concerns are going through the roof. Engineering teams are scrambling to determine how to conduct better in-field or online testing because test no longer can be an afterthought. This has been a common theme across the automotive ecosystem for the past few years, and as the automot... » read more

Fix Processes, Then Silos
By Ed Sperling - 09 Feb, 2017 - Comments: 0

Jack Welch, former CEO of GE, was a big proponent of what he called a "boundaryless corporation." It was a good sound bite, but it pales in comparison to former Intel CEO Andy Grove's philosophy of working out of a cubicle, just like the rest of his staff. While it's great to have corporate buy-in for breaking down silos, which are vertically integrated, the real problem for semiconductor c... » read more

What Can Be Cut From A Design?
By Ann Mutschler - 09 Feb, 2017 - Comments: 0

A long-standing approach of throwing everything into a chip increasingly is being replaced by a focus on what can be left out it. This shift is happening at every level, from the initial design to implementation. After years of trying to fill every square nanometer of real estate on a piece of silicon with memory and logic, doubling the number of [getkc id="26" kc_name="transistors"] from on... » read more

Power State Switching Gets Tougher
By Ann Mutschler - 12 Jan, 2017 - Comments: 0

Power state switching delay is a key factor in minimizing power, and getting it right frequently means the difference between a successful design and a dead chip. But tradeoffs are intricate, complex and often involve judgment calls, making this a place where designs can go completely awry. For years, traditional, full-swing [gettech id="31093" comment="CMOS"] process technologies were used ... » read more

Low-Power Design Is A Corporate Mindset At ARM
By Mentor, a Siemens Business - 07 Dec, 2016 - Comments: 0

The use of the PowerPro platform in the methodology outlined in this paper provides ARM with an RTL design flow which is power-centric. The ability to perform daily RTL power analysis at the block/unit level provides rapid turnaround on the power trend, while weekly analysis provides more complete benchmark reference metrics.

Timing Closure Issues Resurface
By Ed Sperling - 07 Dec, 2016 - Comments: 1

Timing closure has resurfaced as a major challenge at 10nm and 7nm due to more features and power modes, increased process variation and other manufacturing-related issues. While timing-related problems are roughly correlated to rising complexity in semiconductors, they tend to generate problems in waves—about once per decade. In SoCs, timing closure problems have spawned entire methodolog... » read more

7nm Design Success Starts With Multi-Domain Multi-Physics Analysis
By Arvind Vel - 28 Nov, 2016 - Comments: 1

Companies can benefit from advancements in the latest semiconductor process technology by delivering smaller, faster and lower power products, especially for those servicing mobile, high performance computing and automotive ADAS applications. By using 7nm processes, design teams are able to add a lot more functionality onto a single chip and lower the power consumption by scaling operating volt... » read more

Teaching Computers To See
By Ann Mutschler - 16 Nov, 2016 - Comments: 0

Vision processing is emerging as a foundation technology for a number of high-growth applications, spurring a wave of intensive research to reduce power, improve performance, and push embedded vision into the mainstream to leverage economies of scale. What began as a relatively modest development effort has turned into an all-out race for a piece of this market, and for good reason. Mark... » read more

Partitioning For Power
By Ed Sperling - 14 Nov, 2016 - Comments: 0

Examine any smartphone design today and most of the electronic circuitry is "off" most of the time. And regardless of how many processor cores are available, it's rare to use more than a couple of those cores at any point in time. The emphasis is shifting, though, as the mobility market flattens and other markets such as driver-assisted vehicles and IoT begin gaining traction. In a car, turn... » read more

Energy Harvesting Gains Steam
By Ann Mutschler - 10 Nov, 2016 - Comments: 0

Energy harvesting is gaining traction with a surge in ultra-low-power IoT applications, ranging from inventory tracking, wearables and drones, to vibration sensors for motors in industrial settings. The idea that machines could run without batteries—or that energy could be harvested either from motion or ambient sound waves or chemical reactions to augment battery power—has been in the w... » read more
