Low Energy Efficiency

There is an important difference between low power and low energy in SOC design. Low power focuses on instantaneous power consumption. This is frequently done to deal with cooling and heat dissipation issues. Of course, it serves as a prerequisite for low energy design, which seeks to reduce overall power consumption over time.… Read More

As the months of 2020 passed by, I started noticing more and more people sporting what looked like fashionable ear accessories. I’m of course referring to True Wireless Stereo (TWS) earbuds. With the rapid increase in online meetings due to social distancing requirements, it appeared that adoption of TWS earbuds was even faster… Read More

Probing UPF Dynamic Objects

UPF was created to go beyond what HDL can do for managing on-chip power. HDLs are agnostic when it comes to dealing with supply & ground connections, power domains, level shifters, retention and other power management related elements of SoCs. UPF fills the breach allowing designers to specify in detail what parts of the design… Read More

CDC Low Power

Clock domain crossing (CDC) analysis is unavoidable in any modern SoC design and is challenging enough to verify in its own right. CDC plus low power management adds more excitement to your verification task. I wrote on this topic for another solution provider last year. This time I want to intro an interesting twist on the problem,… Read More

Flex Logix Expands Its eFPGA Footprint with a Low Power Comms Design Win from OpenFive

Embedded FPGA use is on the rise. The programmability offered by this kind of IP finds many applications in complex SoCs. There was a recent announcement that OpenFive had licensed Flex Logix’s eFPGA to develop a low power communications SoC. The part required a large eFPGA. The news was reported on SemiWiki here. This announcement… Read More

In the early days of Atrenta I met with Ralph Marlett, a distinguished test expert with many years of experience at Zuken and Recal Redac. He talked me into believing we could do meaningful static analysis for DFT-friendliness at RTL. His work with us really opened my eyes to the challenges that test groups face in integrating their… Read More

UPF hierarchy

As if engineers did not have enough difficulty just getting everything right so that their designs are implemented functionally correct, the demands of lowering power consumption require changes that can affect functionality and verification. Techniques such as power gating, clock gating, mixed supply voltage, voltage … Read More

5G NB IoT Processor from Synopsys

If you are like me, you will get a 5G phone because of the high bandwidth it offers. However, there is a lot more to 5G than just fast data. In fact, one of the appealing features of 5G is low bandwidth communication. This is useful for edge devices that perform infrequent and low volume data transfers and depend on long battery life. Prior… Read More

WEBINAR: The Brave New World of Customized Memory
by Randy Smith on 08-08-2019 at 10:00 am

The need to design low power devices is not new. However, the criticality of lowering the power consumption of chip designs has never been as important as it is now. In 1989, I purchased one of the first consumer cell phones produced by Panasonic. The battery was the size of a brick, but only about a third of the thickness. If the battery… Read More


Synopsys Low Power Workshop Offers Breadth and Depth

Synopsys Low Power Workshop Offers Breadth and Depth
by Bernard Murphy on 06-18-2019 at 5:00 am

Synopsys seems to particularly excel at these events, whether in half-day tutorials at conferences or, as in this case, in a full-day on-site workshop. You might think there’s not much that can be added in this domain, other than to bring low-power newbies up to speed, but you’d be wrong. This event set the stage with surveys on needs… Read More
