Bugs That Kill


Are simulation-resistant superbugs stifling innovation? That is a question Craig Shirley, president and CEO of Oski Technology, asked a collection of semiconductor executives over dinner. Semiconductor Engineering was invited to hear that discussion and to present the key points of the discussion. To promote free conversation, the participants, who are listed below, asked not to be quoted di... » read more

Utilizing Clock-Gating Efficiency To Reduce Power In RTL Designs


With the advent of the consumer era and the popularity of mobile applications, power optimization is the mantra of the day. Designers go through several iterations to optimize power in order to achieve their power budgets. The average Clock-Gating Efficiency for a design is a much better indicator of dynamic power consumption because it is a measure of both how many and how long registers are g... » read more

System-Level Power Modeling Takes Root


Power, heat, and their combined effects on aging and reliability, are becoming increasingly critical variables in the design of chips that will be used across a variety of new and existing markets. As more processing moves to edge, where sensors are generating a tsunami of data, there are a number of factors that need to be considered in designs. On one side, power budgets need to reflect th... » read more

Does Power Verification Work?


Functional verification continues to evolve, but power verification—a somewhat new concern—remains at levels of sophistication reminiscent of functional verification 30 years ago. When will power verification catch up and what must to happen to make it possible? These are questions that the industry is still grappling with, and not everyone believes they require answers. Functional error... » read more

What Happened To UPF?


Two years ago there was a lot of excitement, both within the industry and the standards communities, about rapid advancements that were being made around low-power design, languages and methodologies. Since then, everything has gone quiet. What happened? At the time, it was reported that the [gettech id="31043" comment="IEEE 1801"] committee was the largest active committee within the IEEE. ... » read more

Finite State Machine Synthesis In Programmable Circuits


Well, summer has been and gone; and for most of us it was a time to relax and reflect on our working practices. What can we do to achieve better results? And what can we do to break out of the routine of working on so many revisions? For me, one of my summer break ponderings was thinking back on a trick I learned while working with my colleagues at the Silesian University of Technology. C... » read more

Synthesis Of Energy-Efficient FSMs Implemented In PLD Circuits


The paper presents an outline of a simple synthesis method of energy-efficient FSMs. The idea consists in using local clock gating to selectively block the clock signal, if no transition of a state of a memory element is required. The research was dedicated to logic circuits using Programmable Logic Devices as the implementation platform, but the conclusions can be applied to any synchronous ci... » read more

Power Modeling And Analysis


Semiconductor Engineering sat down to discuss power modeling and analysis with [getperson id="11489" p_name="Drew Wingard"], chief technology officer at [getentity id="22605" e_name="Sonics"]; [getperson id="11763" comment="Tobias Bjerregaard"], CEO for [getentity id="22908" e_name="Teklatech"]; Vic Kulkarni, vice president and chief strategy officer at [getentity id="22021" e_name="ANSYS"]; An... » read more

The Problem With Clocks


The synchronous digital design paradigm has enabled us to design circuits that are well controlled, but that is only true if the clocks themselves are well controlled. While overdesign techniques ensured that to be the case in early ASIC development, designs today cannot afford such luxuries. As we strive for lower power and higher operating frequencies, the clock has become a critical desig... » read more

Routing Signals At 7nm


[getperson id="11763" comment="Tobias Bjerregaard"], [getentity id="22908" e_name="Teklatech's"] CEO, discusses the challenges of designs at 7nm and beyond, including power integrity, how to reduce IR drop and timing issues, and how to improve the economics of scaling. SE: How much further can device scaling go? Bjerregaard: The way you should look at this is [getkc id="74" comment="Moore... » read more
