Summary
The growing significance of ultra-short reach (USR) interfaces on 2.5D packaging technology has led to a variety of electrical definitions and circuit implementations. TSMC recently presented the approach adopted by their IP development team, for a parallel-bus, clock-forwarded USR interface to optimize power/performance/area… Read More
Multi-Vt Device Offerings for Advanced Process Nodes
Summary
As a result of extensive focus on the development of workfunction metal (WFM) deposition, lithography, and removal, both FinFET and gate-all-around (GAA) devices will offer a wide range of Vt levels for advanced process nodes below 7nm.
Introduction
Cell library and IP designers rely on the availability of nFET and pFET… Read More
Key Semiconductor Conferences go Virtual
This last week the 2020 Symposia on VLSI Technology and Circuits (VLSI Conference) was held as a virtual conference for the first time and it was announced today (June 24th) that this year’s IEDM conference will also be held as a virtual conference.
“The IEDM Executive Committee has decided that in the interest of prioritizing the… Read More
Design Technology Co-Optimization (DTCO) for sub-5nm Process Nodes
Summary
Design Technology Co-Optimization (DTCO) analysis was pursued for library cell PPA estimates for gate-all-around (GAA) devices and new metallurgy options. The cell design and process recommendations are a bit surprising.
Introduction
During the “golden years” of silicon technology evolution that applied Dennard… Read More

DVCon 2020 Virtual Follow-Up Conference!
As most of you know DVCon 2020 was our first conference to be cut short by the Pandemic. SemiWiki bloggers Bernard Murphy, Mike Gianfagna, and I were there with full schedules but at the last minute it was called off. It really was an eerie feeling, the emptiness of it all.
The rest of our EDA live events followed suit and went virtual … Read More
Fractal CEO Update 2020
Rene Donkers, the company’s Co-founder and CEO, started his EDA career at Sagantec where he became responsible for world wide customer support and operations management. Ten years ago, Rene and a handful of people noticed a need in the design community for a standardized (portable) IP Validation approach to replace internal… Read More
Webinar: Optimize SoC Glitch Power with Accurate Analysis from RTL to Signoff
I had the opportunity to preview an upcoming webinar from Synopsys on SoC Glitch Power – what it is and how to reduce it. There is some eye-opening information in this webinar. Glitch power is a bigger problem than you may think and Synopsys has some excellent strategies to help reduce the problem. The webinar is available via replay… Read More
Webinar on Methods for Monte Carlo and High Sigma Analysis
There is an old saying popularized by Mark Twain that goes “There are three kinds of lies: lies, damned lies, and statistics.” It turns out that no one can say who originated this saying, yet despite however you might feel about statistics, they play an important role in verifying analog designs. The truth is that there are large numbers… Read More
