The Fundamental Power States For UPF Modeling And Power Aware Verification


The IEEE 1801-2015 specifies the new semantics of power states through the ‘add_power_state’ UPF command. This new construct primarily allows incremental refinement of power states for power domains and its associated supply sets. The refinement concepts are actually originated from the fundamental conceptual set of power states termed as indefinite, definite, and deferred power states. In ... » read more

Tech Talk: Extending DRAM


Bruce Bateman, senior principal engineer at Kilopass, talks about how to extend the life of DRAM and how to work with smaller, denser memory.   Related Stories Executive Insight: Charlie Cheng Kilopass’ CEO talks about how to cut the capacitor in DRAM and why that’s important in the data center. » read more

Verification Of Low-Power Designs With Portable Stimulus


In a recent blog post, Steve Carlson talked about the use of software-driven tests to support concurrent power and performance analysis. Generation of software-driven tests is one of the key technologies that will be enabled by the upcoming standard from Accellera's Portable Stimulus Working Group (PSWG). Portable stimulus spans functional verification as well as performance validation, so PSWG... » read more

7nm Power Issues And Solutions


Being able to achieve 35% speed improvement, 65% power reduction and 3.3X higher density makes adopting a 7nm process for your next system-on-chip (SoC) design seem like an easy decision. However, with $271 million in estimated total design cost and 500 man-years it would take to bring a mid-range 7nm SoC to production, companies need to carefully weigh the benefits against the cost of designin... » read more

The Time Dimension Of Power


Power is the flow of energy over time. While both aspects of that equation are important, they are important to different people in different ways. Energy that moves too quickly can cause significant damage. Too much energy moving over time can mean a non-competitive product, from battery-powered devices to a wide array of locations such as the datacenter. When the industry talks about power... » read more

Can Low-Power Devices Be Secure?


Successfully designing a low-power, high-performance chip design is an accomplishment, but effectively implementing cybersecurity in such devices makes it much more difficult. Safety, particularly functional safety for automotive and military/aerospace applications, also can be a prime concern in creating low-power, high-performance integrated circuits and systems. When combined with securit... » read more

Three Power-Saving Techniques Using PCI Express IP


The increasing data traffic between devices in a computing application environment is causing a large power footprint, and for that reason designers are looking for ways to lower the power consumption of their SoCs during sparse or idle times. The smaller, battery-powered devices are often idle and in deep sleep modes, but these deep power saving modes come at the cost of slow resume times to s... » read more

Saving Energy In The Fab


It’s not an exaggeration to say that integrated circuits are a critical component of any effort to reduce global carbon dioxide emissions. The most efficient engines depend on microcontrollers to optimize fuel consumption. Global shipping uses sophisticated simulators for load balancing and route planning. Computing power that once needed room-sized cooling units now fits in a battery-powered... » read more

Tech Talk: Earlier Software


Malte Doerper, senior manager of product management at Synopsys, talks about the big "shift left" for software, where the problems crop up, and how to save as much as a year of development time with automation and better methodologies.   Related Stories Bridging Hardware And Software The need for concurrent hardware-software design and verification is increasing, but are engine... » read more

Silicon Photonics Comes Into Focus


Silicon photonics is attracting growing attention and investment as a companion technology to copper wiring inside of data centers, raising new questions about what comes next and when. Light has always been the ultimate standard for speed. It requires less energy to move large quantities of data, generates less heat than electricity, and it can work equally well over long or short distances... » read more
