Mechanical Meets Electrical


By Ed Sperling For the first part of the 20th century mechanical engineering dominated almost everything in technology. For the second half, once the transistor and the integrated circuit became well entrenched, those two disciplines largely divided up the tech market. More recently, however, they are being forced to collaborate in teams that historically had nothing in common. While the co... » read more

Margin Of Error


By Ed Sperling Adding extra circuits and silicon area to a chip has always been frowned upon by chipmakers. Extra silicon means extra money, and for most chips the least expensive is always the better choice. But at advanced process nodes, margin also can slow performance, increase power consumption, and make it harder to achieve timing closure. The obvious solution is to reduce margin thro... » read more

Step Away From the Spreadsheet


By Ann Steffora Mutschler Engineers today spend more than a quarter of their time trying to meet power specifications. A survey of more than 700 engineers by Calypto illustrates just how important and time-consuming power management is today for engineering teams. As consumer devices grow ever more complex, the need to deal with, analyze and optimize power at not just the RTL but at the sys... » read more

Experts At The Table: Low-Power Verification


Low-Power Engineering sat down to discuss the problems of identifying and verifying power issues with Barry Pangrle, solutions architect for low-power design at Mentor Graphics; Krishna Balachandran, director of low-power verification marketing at Synopsys; Kalar Rajendiran, senior director of marketing at eSilicon; Will Ruby, senior director of technical sales and support at Apache Design; and... » read more

A Brief History Of Power Formats


Barry Pangrle A lot has happened in the industry in the way of power format standards over the past seven years. I’m going to attempt to hit on some of the highlights over that time period, especially with regards to the “Big 3” EDA vendors to hopefully put it all into better context for our readers. Early on, circa 2005, Mentor Graphics was working on a power format referred to as th... » read more

Low-Power Verification


Low-Power Engineering talks about how to verify the power portion of semiconductor designs with Krishna Balachandran of Synopsys; Barry Pangrle of Mentor Graphics; Kalar Rajendiran of eSilicon; Will Ruby of Apache Design, and Lauro Rizzatti of Eve-USA. [youtube vid=covy6ku6RgA] » read more

Model Behavior


By Achim Nohl In this post, I would like to share some perspectives on the transaction-level models needed for the creation of virtual prototypes. Just recently, TLMCentral kicked off a contest seeking the “best” model for a mobile phone sensor device. What actually makes a “good” model? The most ad-hoc answer to this question historically has been that the best model is the fastest an... » read more

Reverse Engineering


By Ed Sperling Fabs and foundries frequently have been the savior of flawed designs, fixing problems such as power and performance, identifying design issues and often developing solutions to those problems. Over the next couple of process nodes, and in stacked die that will span multiple processes, there will be far fewer saves coming from the back end. Double and triple patterning, stress... » read more

Model Report Card


By Ann Steffora Mutschler From its perspective as a leader implementing system level design methodology, STMicroelectronics is uniquely positioned to discuss issues and challenges related to the use of models in a variety of use cases. System-Level Design had the opportunity recently to discuss challenges in the modeling space with Jean-Marc Chateau, director of ST’s SPT (System Platforms a... » read more

Ambient Computing: Interdependencies Rule


By Ann Steffora Mutschler Ambient computing: Just the concept conjures up images of a Star Trek-like ‘Computer’ that is ever at the ready, awaiting a query at any moment, and which can discern as well as perform significant tasks. While Apple’s Siri gets there partway, it is significant because the concepts that make the technology possible behind the scenes draw upon a multidisciplinary... » read more
