Customer perspective: STMicroelectronics
By Ed Sperling - 21 Jul, 2011 - Comments: 0

By Ann Mutschler With eight SoC designs currently in development on its 28nm manufacturing process, STMicroelectronics is well acquainted with the power challenges of making those designs work. LPE discussed these issues with Philippe Magarshack, ST’s Technology R&D Group Vice-President. What follows are excerpts of that conversation. LPE: What are the biggest challenges in getting ST... » read more

One On One: ARM CTO Mike Muller
By Ed Sperling - 01 Jul, 2011 - Comments: 0

LPE: How far does Moore’s Law extend forward and what are we likely to encounter along the way? Muller: The good news is there is no known solution for 7nm. That implies that between now and then it’s okay. When I talk to people they seem fairly confident they’re going to get there. Exactly how they don’t know. Will there be any miracles needed? Yes, probably one or two. But 14nm and ... » read more

The Tao Of Software
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Ed Sperling and Pallab Chatterjee As software teams continue to race past hardware teams in numbers of engineers, hours spent on designs and NRE budgets, companies are beginning to question whether there needs to be a fundamental shift in priorities and strategy. The problem is that it takes far too long to write and debug the software and to get it working on the hardware, even with vir... » read more

5 Ways To Cut Power
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Ed Sperling Low energy consumption with minimal leakage has emerged as the most competitive element in an IC design, regardless of whether it involves a plug, a battery, or whether it’s powered by a gasoline engine. While components on an SoC aren’t always power-aware, they’ll have to be in the future as consumers focus first on energy efficiency. With rising fuel costs, a concern ... » read more

System Models Are Changing
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Pallab Chatterjee Historically system-level modeling was based on making sure there were no timing crashes on the main data bus. After that it was multi-core conflict resolution, distributed memory routing and, most recently, verifying the correct core actually has access to the correct memory with the data that is relevant being available. All of these areas are now subject to an additi... » read more

Too Soon For Wide I/O
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Ann Steffora Mutschler When 3D ICs are prevalent, Wide I/O is sure to be there. But where does the technology stand today? Considering the amount of buzz and hype, it would be easy believe it is being implemented in production designs today. Wide I/O is a very brute-force way of solving the problem of trying to get latency down with a high-speed memory interface, explained Navraj Nandra,... » read more

Managing Physical Effects
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Ann Steffora Mutschler Managing the physical effects from manufacturing is becoming increasingly critical as designs grow in size and process geometries dive lower. Just keeping track of these effects in a billion-gate design is a daunting task. At advanced manufacturing nodes, the capacitance and inductance effects make the design much harder—and that includes both on-die and off-die ... » read more

Extraction, Power And Final Silicon
By Ed Sperling - 12 May, 2011 - Comments: 0

By Ann Steffora Mutschler As semiconductor technology scales down, manufacturing effects are coming front and center, putting constant pressure on design teams to make sure that silicon can be modeled through the extraction process while performing analysis accurately. Extraction technology is one of the basic components needed to gain an accurate measurement of power, timing and signal int... » read more

Applications And Low Power
By Ed Sperling - 12 May, 2011 - Comments: 0

By Pallab Chatterjee As new process technologies are being developed to make devices smaller, they are also driving the operating power lower for the devices and systems. The goal is to reduce the power requirements for the system and hence increase the functional life on a single battery charge. This concept has worked in the semiconductor industry from 10-micron processes down to the 6... » read more

The Impact Of Triple Play
By Ed Sperling - 12 May, 2011 - Comments: 0

By Ann Steffora Mutschler Not so long ago there were multiple networks that supported different kinds of traffic—a telecommunications network based on high-reliability protocols, the Internet for burst-centric data traffic and video distribution networks. From the consumer standpoint that was highly inefficient. Managing three subscriptions from three service providers was unnecessary, w... » read more
