Power Limits Apps In The IoT


The applications in the IoT are seemingly limitless, but the power is one thing that can’t be. Mary Ann White at Synopsys reminded me that a lot of the energy harvesting devices are super low power and there is a reason why they use just a simple LCD-type display. But we agree it would be so cool if we could have color LCDs that still only consume low power. Of course, I have no doubt tha... » read more

Power Delivery Network Verification Coverage


Power grid verification is a challenge, and there are no industry standards for design teams to follow that will verify the power grid for power and signal integrity issues. In other areas there is typically a verification plan with checks to perform, and when successfully completed, the design is then considered verified to proceed to tape-out. Having high coverage in the power grid’s power... » read more

Blog Review: Nov. 12


ARM's Eoin McCann provides a primer to software-defined networking, which uses a higher level of abstraction to create a centralized controller. This is a new twist on networking—with a bit of deja vu thrown in. Mentor's Matthew Ballance points to a perfect storm for verification—shrinking features, more layers and more embedded processors. He has some tips for how to deal with all of t... » read more

What’s Working For Power Verification


Getting power verification right — or at least good enough — is the source of frustration for many design teams. Add to this the fact that there is no one right way to accomplish it just compounds the challenge. Fortunately, there are a number of options that are working to varying degrees, starting with static verification, according to Bernard Murphy, CTO of Atrenta. “Static verifica... » read more

Designing For Energy Efficiency


Swiss watchmakers have nothing to worry about for the moment. As top-name companies crowd into the wearable market with full-featured watches, limits on battery life and frequent charges undoubtedly will limit their popularity. Smart watches look cool or clunky, depending upon your perspective, but none of them lasts long enough between charges to be a serious market contender. That's certai... » read more

Are More Processor Cores Better?


Up until the early 2000s, each generation of processor was faster, used more exotic architectures, had deeper pipelines, used more transistors, ran at higher clock frequencies and consumed more power. In fact power was rising faster than performance and led to the extrapolation that within a few generations, processors would run as hot as nuclear reactors. Something had to change, and that c... » read more

Keeping Up With The Productivity Challenge


Until recently, EDA software rode the coattails of increasing processor performance as part of its drive to continue providing faster and more powerful development software to the people designing, among other things, the next generation of faster processors. It was a fortuitous ring. Around the turn of the century, with the migration to multi-core computing systems, all of that changed. In ord... » read more

Tech Talk: Power Sign-Off


Calvin Chow, area technical manager at Ansys, talks about power sign-off for complex SoCs at advanced nodes, including early stage prototyping, the importance of context, accurate power modeling of sub-blocks, and simulation of power-delivery networks. [youtube vid=MN4TjZ3dHVk] » read more

IP Design Essentials For Power Integrity


Smart connectivity is the new mantra of today – the ability to connect to anything, anywhere and at any time. With such technology enablement, low power is not a choice but an expectation. Whether it is a connected device, or a system that is part of the infrastructure, they are driven to integrate various functionality such as high speed computing, high-speed memory, memory interfaces, radio... » read more

Power And Noise Integrity For Analog / Mixed-Signal Designs


The convergence of advance process technology, increasing levels of integration, and higher operating frequencies pose considerable challenge to IP designers whose circuits are required to function in variety of conditions. Full-custom and mixed signal circuit designers ensure that their circuits will function by simulating for various operating conditions (PVT, input stimuli, etc). One key asp... » read more
