IP And Power
By Brian Bailey - 08 Mar, 2018 - Comments: 0

[getkc id="108" kc_name="Power"] is quickly becoming a major differentiator for products, regardless of whether they are connected to a wall outlet or dependent on a battery. At the same time, increasing amounts of a chips content comes from third-party [getkc id="43" kc_name="IP"]. So how do system designers ensure that the complete system has an optimal power profile, and what can they do to ... » read more

What’s Missing In Low-Power Verification
By Ed Sperling - 09 May, 2013 - Comments: 0

By Ed Sperling Ask two engineers what low-power verification is and you’ll likely get the same checklist that includes confidence in the overall design, good coverage, a long list of corner cases, and other items in a checklist. Ask them how to reach that goal you’ll almost certainly get different answers—or maybe no answers at all. Power has emerged as a ubiquitous concern in design,... » read more

Dealing With The Data Glut
By Ann Mutschler - 11 Apr, 2013 - Comments: 0

By Ann Steffora Mutschler Tools like emulation and simulation are an absolute necessity to design and verify today’s complex SoCs, but what happens when you want to do power analysis and the file sizes are too massive for the emulator to handle? Even with an emulator a five-minute mobile phone call could take three months. Understandably, this issue is causing pain to many design teams... » read more

Changes Ahead In Low-Power Design
By Ed Sperling - 25 Mar, 2011 - Comments: 0

One of the interesting things about low-power designs in ICs is just how effectively power-saving techniques are being designed into chips these days. At most of the larger chipmakers, and even at an increasing number of midsize fabless companies, the concepts for implementing low-power techniques are well understood, well tested and thoroughly familiar. Two years ago, when the mainstream of... » read more

Verifying Low-Power Designs
By Ed Sperling - 14 Jan, 2010 - Comments: 0

By Ed Sperling Power islands and multiple voltages used to be reserved for cell phone and process companies, but as more companies move to 65nm and 45nm process nodes these approaches to saving power—particularly in chips with multiple cores—are becoming mainstream. The problem isn’t in the architecture of the chips, although that certainly brings its own set of challenges. More and m... » read more

What follows are ... » read more

Defining Reliability In Low-Power Designs
By Ed Sperling - 15 Oct, 2009 - Comments: 0

By Ann Steffora Mutschler Having a clear understanding of what reliability means for a particular low-power application can make a significant difference when it comes to communicating with engineering team members and customers. Is reliability simply a question of how long a device can run without errors? And what happens to reliability when power modeling, verification and other design tec... » read more
