Power Modeling: Use Cases Need to be Clearly Defined
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

By Ann Steffora Mutschler Low-Power/High-Performance Engineering sat down to discuss power modeling during the Design Automation Conference with Vic Kulkarni, senior vice president and general manager at Apache Design; Paul Martin, design enablement and alliances manager at ARM; Sylvan Kaiser, CTO at Docea Power; and Frank Schirrmeister, group director, product marketing for system deve... » read more

Experts At The Table: Black Belt Power Management
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

By Ann Steffora Mutschler With approximately 80% of SoC content reused from past designs or brought in from internal and external IP sources, a significant part of a design engineer’s job today is writing glue logic and verifying to make sure the integrated system communicates as dictated by the specification. Integration challenges continue to mount with the increasing amount of black ... » read more

Training The Next Gen For Low Power
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

Reflecting on my time at this year's Design Automation Conference, I am quickly reminded that I work in the most fascinating industry I can think of. Having the opportunity to discuss deep technical low power design issues, forward-looking challenges as well as the business implications face to face with thought leaders is inspiring and invigorating. With the amount of brain power filling Mosco... » read more

Mixed-Signal Integration Drives Platform Chips
By Ann Mutschler - 10 May, 2012 - Comments: 0

Not only are there low-power challenges with just about every design today, there are also very interesting issues concerning integration of mixed-signal onto chips. As chips are get bigger and more costly to develop, many companies are turning to platform chips that can be used in a smartphone and in a tablet with slightly different twists in the functionality of that platform chip because ... » read more

Fundamentals For 3D IC Flows
By Ann Mutschler - 05 Apr, 2012 - Comments: 0

While true 3D ICs are a few years off, 2.5D is here. There are some key differences, namely that with 2.5D the interposer is a passive die, but there also are some fundamental shared requirements. Samta Bansal, senior product marketing for Silicon Realization at Cadence asserted that first, the digital, custom and package environments must be seamless. “There has to be a co-design between ... » read more

Flexibility Vs. Portability In Emulation
By Ann Mutschler - 08 Mar, 2012 - Comments: 0

Complete and exhaustive verification of low-power designs requires a substantial effort and part of this includes running real applications on the hardware. Simulators fall short as designers realize that the so-called testbenches they create are artificial and don’t necessarily represent typical applications. As such, this is the sweet spot for emulators, also known as hardware accelerators,... » read more

A Necessary Duo: IP And Assertions
By Ann Mutschler - 08 Mar, 2012 - Comments: 0

By Ann Steffora Mutschler Assertions are key to complete and accurate verification, as I dove into here, and there are implications for IP as well. In the case of an embedded processor core that is shipped out as an RTL by the IP vendor, and then used by an engineering team to create a cell phone SoC or to create a consumer SoC for a set-top box or what have you, that core goes into an end ... » read more

The Low Power-System Level Connection
By Ann Mutschler - 09 Feb, 2012 - Comments: 0

I don’t know about you but I am fired up (in a good way) with everything surrounding low power and design at the system level. We are at a point where the challenges are pretty well understood, we can see the way forward in many areas, but what needs to happen next is the evolution of technology that will compel users to adopt the new techniques, which may have yet to be created. Engineeri... » read more

Peace Overture
By Ann Mutschler - 12 Jan, 2012 - Comments: 0

One look at the headline and you may think I’m going to suggest that virtual prototyping can solve the myriad issues between hardware and software teams but rest assured, I’m not. I will tell you that I’ve heard some promising anecdotes lately, and that is a little bit encouraging. When you finish reading, please chime in with your comments! In the course of interviewing Achim Nohl, te... » read more

Cell Phone Radiation: Taboo Topic, Interesting Science
By Ann Mutschler - 01 Dec, 2011 - Comments: 0

Amid a growing consumer concern for possible health issues associated with radiation, more attention is being paid to what’s being generated by mobile devices—particularly the ones we hold next to our brains. Legislation has been introduced in some parts of the country, with varying success, aimed mainly at informing consumers about the potential risks and giving suggestions for reducing ex... » read more
