Bridging The Gap
By Ann Mutschler - 01 Dec, 2011 - Comments: 0

We talk all the time about hardware/software co-design, co-verification, etc., but what is really interesting now is how vital the connection is between power awareness and system-level design. Yes, it sounds obvious, but so far this is an untapped market with ideas still being batted around. As discussed in Parts 1, 2 and 3 of my article series on energy and power, to achieve the best power... » read more

Buzzwords: Dead or Alive?
By Tiffany Sparks - 17 Nov, 2011 - Comments: 0

By Tiffany Sparks “Time-to-market” and “time-to-volume” – are they overused marketing buzzwords? Until recently, I would have argued yes. After all, it seems like very few solutions in the semiconductor supply chain are not marketed along the lines of addressing time-to-volume or time-to-market challenges. But just because buzzwords become trite, it doesn’t mean they aren’t st... » read more

Power Intent Formats: Isolation
By Luke Lang - 03 Nov, 2011 - Comments: 0

By Luke Lang Last month, I discussed power domain for all three power formats: CPF, UPF 1.0, and IEEE 1801. I mentioned isolation but mainly used it to explain power domain. This month’s blog will address isolation in detail. First, isolation cells are required at off-to-on domain crossings. When a domain is shut off, all of its output nets become undriven. If these floating nets drive direct... » read more

Innovation At The Core
By Barry Pangrle - 03 Nov, 2011 - Comments: 0

By Barry Pangrle A number of next-generation ARM-based multi-core systems are starting to show up in the press. Nvidia has released information on its upcoming Tegra 3 (also known as “Kal El”). At last week’s ARM Techcon in Santa Clara, ARM gave several presentations around its Cortex-A7 (Kingfisher) and Cortex-A15 (Eagle) architectures and collectively about its big.LITTLE strategy. Qua... » read more

More EMI Mitigation
By Ann Mutschler - 03 Nov, 2011 - Comments: 0

With electromagnetic interference a major design challenge today in any product that sends or receives a signal, determining how to lessen the impact of this phenomenon was addressed to a large extent in my article, “EMI Cuts a Wide Swath,” but there are a few additional techniques that are important to highlight. Erick Olsen, marketing director at NXP explained that higher performance c... » read more

The Bigger Picture
By Aveek Sarkar - 02 Nov, 2011 - Comments: 0

By Aveek Sarkar IC power consumption is dependent on its supply voltage. To reduce power consumption, and heat dissipation, IC designers strive to design for lower supply voltages. But the threshold voltage that controls switching in digital CMOS devices hasn't scaled accordingly from reliability and other considerations. As the supply voltage reduces down close to the threshold voltage of ... » read more

Noise Coupling Analysis
By Arvind Vel - 06 Oct, 2011 - Comments: 0

By Arvind Shanmugaval Integrating digital and mixed-signal IP blocks in SoCs poses a considerable challenge to verification of power/ground and substrate noise. Traditional methods of power supply noise analysis are unable to meet the demands of today’s highly integrated designs with multiple low- power design techniques. Existing methods also do not provide sufficient capacity or the capabi... » read more

Power Intent Formats: Power Domain
By Luke Lang - 06 Oct, 2011 - Comments: 0

By Luke Lang Starting this month, I will be writing a series of blogs inspired by “Dueling Power Formats”. The article correctly points out that there are currently three power formats: CPF, UPF 1.0, and IEEE 1801. Some designers will find themselves in a position of having to choose a format. Others will need to work with both formats. Regardless of which position one is in, these LP desi... » read more

Intel’s Claremont Near-Threshold Voltage IA Core
By Barry Pangrle - 06 Oct, 2011 - Comments: 0

By Barry Pangrle Intel announced many new technologies at its recent Intel Developer Forum (IDF) held from Sept. 13-15 in San Francisco, but the one announcement that jumped out at me was the unveiling of its work on a near-threshold voltage (NTV) processor named “Claremont.” For this exercise, Intel chose an older Pentium design to help minimize the number of variables the engineers would... » read more

Are We There Yet?
By Ann Mutschler - 06 Oct, 2011 - Comments: 0

We’ve been talking in the industry for as long as I can remember about hardware and software co-design and I’m always curious to hear how that it progressing….or not. I posed this question to Jon McDonald, technical marketing engineer in Mentor Graphics’ design creation synthesis group who is constantly in touch with engineering teams. His take is that hardware and software teams are... » read more
