Performance Analysis On Dark Silicon
By Ann Mutschler - 10 Sep, 2015 - Comments: 0

It’s one thing to do performance analysis on the ‘light’ parts of an SoC design, but what about when most of the silicon is ‘dark?’ Jon McDonald, technical marketing engineer at Mentor Graphics stressed that modeling the effects of turning on and off sections of the silicon is an important part of creating an accurate representation of the system. “Our models support state-based... » read more

Tackling RF Desense Challenges At The Source
By Margaret Schmitt - 14 Aug, 2015 - Comments: 0

Just imagine you are stepping out of the electronics store with your brand new smart phone. You eagerly scroll down your contacts to dial your best friend and proudly tell them the great news, but as soon as they pick up, your reception is gone! What happened? This problem is commonly described as desense, a degradation of the sensitivity of the receiver due to external noise sources. Desens... » read more

Using Automotive-Ready IP To Accelerate SoC Development
By Ron DiGiuseppe - 13 Aug, 2015 - Comments: 0

IP suppliers play a key role in the automotive supply chain to enable high-performance advanced driver assistance system (ADAS) SoCs. Vision-based SoCs may contain a high amount of third-party IP to implement the key embedded vision, sensor fusion, multimedia, security and advanced connectivity functions. And while IP suppliers have permeated the semiconductor ecosystem for consumer, mobile, PC... » read more

What To Do With Power Models
By Ann Mutschler - 13 Aug, 2015 - Comments: 0

Ask any design engineer if they want a power model, and you can guess the answer. As far as what they want to use it for, the answer will vary. When I asked Jem Davies, ARM Fellow, if OEM engineering teams want a comprehensive power model, he said, “Ideally, yes. Perfectly ideally, what they would like to have from us is a model of each individual block of our IP which plugs together in a ... » read more

Think IoT Designs Are Challenging? Try Embedded Systems In The Brain
By Brian Fuller - 13 Aug, 2015 - Comments: 0

There’s low power and then there’s low power. There are amazing applications and then there are amazing applications. Today the bleeding edge of low power design is not so much in IoT (although excellent work is being done in that space) but in medical, where the stakes are high and possible outcomes life-altering. Chet Moritz, associate professor with the University of Washington’s... » read more

How To Fix Common Power Problems
By Arvind Narayanan - 13 Aug, 2015 - Comments: 0

As the industry moves to ever more advanced technology nodes, managing power has emerged as a primary challenge in modern SoC design. With smaller nodes, the wires become taller and narrower, which increases the resistivity and leads to more pronounced voltage drop effects. Electro-migration effects are also more severe at advanced nodes, causing serious reliability concerns. Both RTL synthesis... » read more

Doing More With RTL Power Analysis: Smart Synthesis Architecture
By Anand Iyer - 13 Aug, 2015 - Comments: 0

Traditionally RTL power analysis has been used to understand the design power consumption so that package and power supply designs can start, and designers can then fix any power regression violations in subsequent design iterations. However, migration to finFET processes is causing designers to look at RTL power analysis differently at advanced nodes. FinFET processes have largely addressed... » read more

The Memory And Storage Hierarchy
By Loren Shalinsky - 13 Aug, 2015 - Comments: 0

The memory and storage hierarchy is a useful way of thinking about computer systems, and the dizzying array of memory options available to the system designer. Many different parameters characterize the memory solution. Among them are latency (how long the CPU needs to wait before the first data is available) and bandwidth (how fast additional data can be “streamed” after the first data poi... » read more

Remembering Gary Smith
By Ann Mutschler - 16 Jul, 2015 - Comments: 2

The EDA industry recently said farewell to one of its biggest advocates, Gary Smith, who passed away on July 3. Writing a remembrance for an industry acquaintance can be uncomfortable; writing one for someone who was a friend is just, plain painful. While I had a number of years writing about technology under my belt, by the time I started covering EDA for Electronic Business in 1997 I k... » read more
