Performance Analysis Of Electric Motors For EV Powertrains


Developing a battery EV powertrain is a complex systems problem. This technical paper examines the design and development of electric motors in an EV powertrain, showing how the different design choices — such as motor topology, winding type and cooling system — can be compared and evaluated considering their overall system impact. ANSYS Motor-CAD simulations can help engineers determine wh... » read more

Reducing Software Power


With the slowdown of Moore's Law, every decision made in the past must be re-examined to get more performance or lower power for a given function. So far, software has remained relatively unaffected, but it could be an untapped area for optimization and enable significant power reduction. The general consensus is that new applications such as artificial intelligence and machine learning, whe... » read more

Determining Where Power Analysis Matters Most


How much accuracy is required in every stage of power analysis is becoming a subject of debate, as engineering teams wrestle with a mix of new architectures, different use cases and increasing pressure to get designs out on time. The question isn't whether power is a critical factor in designs anymore. That is a given. It is now about the most efficient way to tackle those issues, as well as... » read more

Which Glitch Is Which?


Glitch is a commonly used term in modern vernacular, used to identify unexpected problems in everything from the space race, web site down time, or a crash of your latest mobile phone app. In electronics design glitch has a more specific meaning, referring to unnecessary signal transitions in a combinational circuit. Eliminating this extra switching activity can save power consumption, especial... » read more

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
