Accurate Power Analysis Using Real Software Workloads


Over the last decade or so, power consumption has become a major issue in the design of many types of electronic products. Of course, power has always mattered for battery-operated devices, but the complexity of portable electronics and the size of the chips they contain have grown significantly. For plugged-in devices, from desktop computers to server racks in a data center, power plays a majo... » read more

Using Less Power At The Same Node


Going to the next node has been the most effective way to reduce power, but that is no longer true or desirable for a growing percentage of the semiconductor industry. So the big question now is how to reduce power while maintaining the same node size. After understanding how the power is used, both chip designers and fabs have techniques available to reduce power consumption. Fabs are makin... » read more

Why Chips Die


Semiconductor devices contain hundreds of millions of transistors operating at extreme temperatures and in hostile environments, so it should come as no surprise that many of these devices fail to operate as expected or have a finite lifetime. Some devices never make it out of the lab and many others die in the fab. It is hoped that most devices released into products will survive until they be... » read more

Getting Ahead With Early Power Analysis


Today’s mobile applications need to cater to a broad set of applications. They can be communications-heavy (Bluetooth and GPS), graphics-intensive (streaming 4K videos), or compute-intensive workloads (AR/VR gaming). At the heart of this processing lies the all-powerful mobile processor, which includes a multi-core CPU, GPU, memory and other IP and subsystems for performing a variety of ta... » read more

The Week In Review: Design


Tools Synopsys revealed a power analysis solution for early SoC design as well as signoff-accurate power and reliability closure. PrimePower has reliability as a major focus, expanding power and reliability signoff and ECO closure capabilities from physical awareness to cell electromigration effects. Supported power types include peak power, average power, clock network power, leakage power, a... » read more

Dealing With System-Level Power


Analyzing and managing power at the system level is becoming more difficult and more important—and slow to catch on. There are several reasons for this. First, design automation tools have lagged behind an understanding of what needs to be done. Second, modeling languages and standards are still in flux, and what exists today is considered inadequate. And third, while system-level power ha... » read more

Estimating Power And Performing Optimization


Power analysis and optimization have gained importance over the last few years. During this time it has become obvious how critical it is to use realistic payloads to accurately estimate power and perform optimization tasks. Designers have a range of different objectives and concerns when it comes to power. On one side, a team wants to ensure that the average power of their chip is low enough t... » read more

2017: Tool And Methodology Shifts


As the markets for semiconductor products evolve, so do the tools that enable automation, optimization and verification. While tools rarely go away, they do bend like plants toward light. Today, it is no longer the mobile phone industry that is defining the direction, but automotive and the Internet of Things (IoT). Both of these markets have very different requirements and each creates their o... » read more

Toward Real-World Power Analysis


The expansion of emulation into new fields, rather than just functional verification, is making it possible to do power analysis over longer spans of time. The result is a fast and effective way to analyze real-world scenarios. This is a new field, and it marks a new use of this technology. While it is still evolving, several ideas have surfaced about the best methodology and the best way to... » read more

Emulation’s Footprint Grows


It wasn't that many years ago that [getkc id="30" comment="emulation"] was an expensive tool available to only a few, but it has since become indispensable for a growing number of companies. One obvious reason is the growing size of designs and the inability of [getkc id="11" kc_name="simulation"] to keep up. But emulation also has been going through a number of transformations that have made i... » read more
