Don’t Be Afraid of the Dark
By Barry Pangrle - 09 Sep, 2010 - Comments: 0

By Barry Pangrle I had the opportunity to attend the Hot Chips conference at Stanford in August and not surprisingly power was an important theme of many of the presentations. IBM had a presentation on adaptive energy management for their POWER7 chip, and Inphi presented on cloud computing without power penalties. Presenters from the Institute of Computing Technology at the Chinese Academy of ... » read more

Challenges In Creating Power-Managed IP
By Bhanu Kapoor - 09 Sep, 2010 - Comments: 0

By Bhanu Kapoor Creating low power IPs worked fairly well—at least until the process technology nodes for which leakage power wasn’t a big issue and clock gating was able to address dynamic power optimization. For 90nm and more advanced process technology nodes, leakage power became a dominant issue and the dynamic power needed better optimization. The use of voltage-based power management... » read more

Burn, Baby, Burn
By Ann Mutschler - 09 Sep, 2010 - Comments: 0

Obviously, software burns power on mobile devices, but exactly how? I found out recently, thanks to Pete Hardee, director of solutions marketing at Cadence Design Systems. Essentially, Hardee said, there are four ways that software burns power, following in order from most to least. First, depending on the mode, various peripherals are on and off and the big one for a smartphone is the LC... » read more

It’s Late Q3 – Do You Know Where Your Chip Is?
By Atrenta - 26 Aug, 2010 - Comments: 0

By Mike Gianfagna Design complexity is increasing. We all get that. But there are other forces at play that may be more significant. Supply chain complexity is also increasing. Outsourcing and off-shoring continue to rise. There exists a general tendency to surrender the fate of your chip to more people. Overlay this situation with the simple fact that in more and more cases the chip defines t... » read more

Power Conference
By Barry Pangrle - 12 Aug, 2010 - Comments: 0

By Barry Pangrle Big 10, ACC, SEC, Big 12, Pac 10? Well, if you’re thinking of universities that’s a start in the right direction (and there will be a quiz at the end of this blog). If you reside outside of the U.S., I apologize for the local reference. When organizing any technical conference, there’s always a challenge in striking a balance between presenting research that may have... » read more

Structural Verification Finds Mixed-Signal LP Errors
By Luke Lang - 12 Aug, 2010 - Comments: 0

By Luke Lang In the last blog, I gave some reasons why there is no low power (LP) analog/mixed-signal solution. However, this does not mean there is no effort in this area. Toward the end of 2009 and early 2010, I worked with a customer to establish a LP analog/mixed-signal structural verification flow. This flow was proven to be extremely helpful. It caught several LP bugs that were not found... » read more

iPhone Has The Power Blues
By Ann Mutschler - 12 Aug, 2010 - Comments: 0

Why do some apps on the iPhone seem to draw more on the battery than others? Is it a matter of power-aware software applications, or is it a hardware issue? Maybe it is a combination of both. I suspect it is due to the intricacies of hardware/software design and verification. I’ve been mulling this over while researching my two articles for this month’s issue of Low-Power Engineering... » read more

What EDA360 Isn’t
By Atrenta - 22 Jul, 2010 - Comments: 0

By Mike Gianfagna The EDA360 White Paper that Cadence Design Systems published a few months back certainly has everyone talking. It’s well written. The messages are compelling. The content has a viral quality. The printed collateral is visually appealing. The microsite is engaging. Most of us only wish we had the marketing budget to do this kind of stuff. A healthy marketing budget is a n... » read more

The Power Of Standards
By Barry Pangrle - 08 Jul, 2010 - Comments: 0

By Barry Pangrle It’s often said that the wonderful thing about standards is that there are so many to choose from. As an industry, EDA seems to have a short memory as VMM and OVM (now becoming UVM), VHDL and Verilog, and more recently UPF and CPF. In cases where one standard suffices, it is horribly inefficient to create multiple “standards.” It is a waste of effort and resources for ED... » read more

Why Low-Power Analog Solutions Are Lacking
By Luke Lang - 08 Jul, 2010 - Comments: 0

By Luke Lang The need for low-power design has been well documented. The demand for low-power design solutions is at an all-time high. Just take a quick glance through the 2010 Design Automation Conference advanced program, and you’ll see that the word “low-power” appears repeatedly. These are exciting times for anyone associated with low-power design. Recent developments in low-power... » read more
