A Fresh Idea in Differential Energy Analysis

A Fresh Idea in Differential Energy Analysis
by Bernard Murphy on 09-06-2018 at 7:00 am

When I posted earlier on Qualcomm presenting with ANSYS on differential energy analysis, I assumed this was just the usual story on RTL power estimation being more accurate for relative estimation between different implementations. I sold them short. This turned out to be a much more interesting methodology for optimizing total… Read More


Webinar: Differential Energy Analysis for Improved Performance/Watt in Mobile GPU

Webinar: Differential Energy Analysis for Improved Performance/Watt in Mobile GPU
by Bernard Murphy on 07-31-2018 at 7:00 am

May want to listen up; Qualcomm are going to be sharing how they do this. There is a constant battle in designing for low power; you don’t accurately know what the power consumption is going to be until you build it, but by the time you’ve built it, it’s too late to change the design. So you have to find methods to estimate power early on,… Read More


Know what 5G is? You’re probably wrong

Know what 5G is? You’re probably wrong
by Tom Simon on 07-12-2018 at 12:00 pm

If you think the transition to 5G will be anything like the transitions before it to 3G or 4G, you are in for a big surprise. Not only will the transition take longer than either of the previous transitions, its ramifications will spread far beyond cell phones and into other areas such as automobiles, AI, healthcare, and commerce. … Read More


ANSYS at DAC

ANSYS at DAC
by Bernard Murphy on 06-21-2018 at 7:00 am

I’m not going to be at DAC this year because I scheduled a fishing trip at the end of June, assuming the show would stay true to form as an early/mid-June event. Still, having to endure salmon and halibut fishing in Alaska rather than slogging around Moscone Center, I can’t pretend to be too disappointed; I’ll be thinking of you all 😎.… Read More


John Lee: Market Trends, Raising the Bar on Signoff

John Lee: Market Trends, Raising the Bar on Signoff
by Bernard Murphy on 06-07-2018 at 7:00 am

I talked to John Lee (GM of the ANSYS Semiconductor BU) recently about his views on market trends and the ANSYS big-picture theme for DAC 2018. He set the stage by saying he really liked Wally’s view on trends (see my blog on Wally’s keynote at U2U). John said these confirm what he is seeing – a trend to specialization, some around… Read More

During TSMC 2018 Technology Symposium, Dr. B.J. Woo, TSMC VP of Business Development presented market trends in the area of mobile applications and HPC computing as well as shared TSMC progress in making breakthrough efforts in the technology offerings to serve these two market segments.

Both 5G and AI are taking the center stage… Read More


Converter Circuit Optimization Gets Powerful New Tool

Converter Circuit Optimization Gets Powerful New Tool
by Tom Simon on 05-09-2018 at 12:00 pm

DC converter circuit efficiency can have a big effect on the battery life of mobile devices. It also can affect power efficiency for wall-power operated circuits. Even before parasitics are factored in, converter circuit designers have a lot of issues to contend with. Optimizing circuit operation is essential for giving consumers… Read More


Peering Over the Timing Edge

Peering Over the Timing Edge
by Bernard Murphy on 05-03-2018 at 7:00 am

I wrote recently about a yield problem which mobile vendors have been finding for devices built in advanced technologies. This was a performance issue (the devices worked fine at lower clock speeds), pointing to a discrepancy in some devices between predicted and observed timing. These were experienced design teams, using state… Read More


A New Problem for High-Performance Mobile

A New Problem for High-Performance Mobile
by Bernard Murphy on 04-04-2018 at 7:00 am

About 6 months ago, ANSYS was approached by a couple of leading mobile platform vendors/suppliers with a challenging problem. These companies were hitting target 2.5GHz performance goals on their (N10 or N7) application processors, but getting about 10% lower yield than expected, which they attributed to performance failures.… Read More
