By Luke Lang Now that power is a key specification, designers are looking into various design techniques to reduce power. One thing that designers realize very quickly is that there is a cost associated with these low-power techniques. Some of these costs are silicon area and design complexity. Very quickly, designers face the tradeoff of cost vs. power saving. In order to analyze this tradeof... » read more

Power Intent Files Drive Low Power Adoption

By Luke Lang - 07 Oct, 2010 - Comments: 0

By Luke Lang “The adoption of EDA tools is actually a very slow process.” This quote by Wally Rhines of Mentor Graphics was highlighted in a red box in the June 2010 issue of EDA Tech Forum. I don’t think most of us would argue with that statement. But there are certainly exceptions to that rule, and low-power design with a power-intent file is one such exception. The concept of a pow... » read more

Structural Verification Finds Mixed-Signal LP Errors

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

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
