Power Management Becomes Top Issue Everywhere


Power management is becoming a bigger challenge across a wide variety of applications, from consumer products such as televisions and set-top-boxes to large data centers, where the cost of cooling server racks to offset the impact of thermal dissipation can be enormous. Several years ago, low-power design was largely relegated to mobile devices that were dependent on a battery. Since then, i... » read more

Power Challenges In ML Processors


The design of artificial intelligence (AI) chips or machine learning (ML) systems requires that designers and architects use every trick in the book and then learn some new ones if they are to be successful. Call it style, call it architecture, there are some designs that are just better than others. When it comes to power, there are plenty of ways that small changes can make large differences.... » read more

Speedcore Power Estimator User Guide


The Achronix Speedcore Power Estimator tool provides a platform to calculate the power requirements for Achronix Speedcore eFPGAs. This user guide gives a detailed overview of the thermal and power needs depending on the device, environment and utilization of components in the design.

Power Reduction In A Constrained World


Back when 40-28nm were new, leakage power for wireless designs dominated the optimization technology focus. This led to multiple VT optimization and power intent management for digital designs to minimize or shut off leakage. As wireless devices moved to FinFET nodes, dynamic power became dominant. As a result, optimization technology focus shifted to build up dynamic techniques to complement y... » read more

Power Modeling And Analysis


Semiconductor Engineering sat down to discuss power modeling and analysis with [getperson id="11489" p_name="Drew Wingard"], chief technology officer at [getentity id="22605" e_name="Sonics"]; [getperson id="11763" comment="Tobias Bjerregaard"], CEO for [getentity id="22908" e_name="Teklatech"]; Vic Kulkarni, vice president and chief strategy officer at [getentity id="22021" e_name="ANSYS"]; An... » 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

Does Power Analysis Need To Be Accurate?


The mere mention of accuracy in power analysis and optimization today can trigger a contentious discussion, even among typically reserved engineers. What is needed and where? Which tools are truly as accurate as claimed? And how much accuracy is actually needed for power analysis, [getkc id="112" kc_name="estimation"], and optimization? First of all, the accuracy required really depends o... » read more

Optimization Challenges For 10nm And 7nm


Optimization used to be a simple timing against area tradeoff, but not anymore. As we go to each new node the tradeoffs become more complicated, involving additional aspects of the design that used to be dealt with in isolation. Semiconductor Engineering sat down to discuss these issues with Krishna Balachandran, director of product management for low-power products at [getentity id="22032"... » read more

ESL Flow is Dead


It was 20 years ago that Gary Smith coined the term [getkc id="48" comment="Electronic System Level"] (ESL). He foresaw the next logical migration in abstraction up from the [getkc id="49" comment="Register Transfer Level"] (RTL) to something that would be capable of describing and building complex electronic systems. He also saw that the future of EDA depended upon who would control that marke... » read more
