An Inside Look At UPF 4.0
By Barry Pangrle - 09 Apr, 2025 - Comments: 0

Energy and power efficiency are increasingly important in today’s products, and the additional complexity in new architectures to incorporate competitive power management schemes has magnified the need for newer and better methodologies for the verification, implementation, and reuse of power intent specifications. This is the focus of the new IEEE 1801-2024 Unified Power Format (UPF) 4.0 ... » read more

Reducing Voltage Guard Band
By Barry Pangrle - 13 Mar, 2025 - Comments: 0

The 2025 International Solid State Circuits Conference was held in San Francisco from February 16th to 20th. IBM presented three papers[1,2,3] based on their Samsung 5nm Tellum II chip. These are interesting in terms of the technology and the specifics about the design and measures taken to improve energy efficiency and reduce power. My first remembrance of a company specializing in guard-ba... » read more

Margin Sensors In The Wild
By Barry Pangrle - 10 Jun, 2024 - Comments: 0

Back in March, I wrote up an article here that looked at how a proxy circuit could be used to measure variations in circuit performance as conditions changed in the operating environment. There were a couple of recent presentations on margin sensors at two of the big EDA vendors' customer engineering forums that we’ll look at as well as another product with an upcoming presentation at DAC. Ma... » read more

TSMC Uncorks A16 With Super Power Rail
By Barry Pangrle - 25 Apr, 2024 - Comments: 0

TSMC showed off its forthcoming A16 process technology node, targeted for the second half of 2026, at its 30th North American Technology Symposium this week. As the foundry moves from nanometer to angstrom process numbering, the new nodes will be prefixed with an “A” designation (instead of “N”) and A16 is the first for TSMC. TSMC said that N2 is still tracking to a 2025 production s... » read more

TSMC: 10nm To Be Greater Than 10% Of 2017 Wafer Revenue
By Barry Pangrle - 18 Jan, 2017 - Comments: 2

TSMC’s financial results for the 4th Quarter of 2016 were released on January 11, 2017 (PST) and showed that year-over-year fourth quarter revenue increased 28.8% and simultaneously net income and diluted EPS both increased 37.6%.  In U.S. dollars, TSMC’s fourth quarter revenue was $8.25 billion.

Green Computing: GPUs Strike Back
By Barry Pangrle - 19 Dec, 2016 - Comments: 1

After the last Platform for Advanced Scientific Computing Conference in June, I wrote an article here about how the custom designed chips from NRCPC (used in the Sunway TaihuLight) and PEZY Computing (used in the PEZY Shoubu) had jumped to the top of the Green500 list with the Sunway TaihuLight also remarkably topping the Top500 list. Well, six months after the report from the IEEE/ACM SC16 Con... » read more
