Pathfinding For Power And Heat
By Ed Sperling - 02 Mar, 2012 - Comments: 0

By Ed Sperling There are many ways to measure power and heat in an IC, and each one of them adds tremendous value to a design. But there are still holes, and those holes are just beginning to get filled. Power and heat have emerged as two of the most persistent problems in advanced designs, and there is no single or simple way to tackle either of them. Nevertheless, there is at least progre... » read more

What Have Models Got To Do With It?
By Achim Nohl - 23 Feb, 2012 - Comments: 0

By Achim Nohl Transaction-level models are the main building blocks of virtual prototypes, which are used for early software development. In my last blog post, I briefly introduced the different kinds of software tasks and the implications for models. Today, I want to talk about the modeling requirements for early SoC bring up. As I mentioned, understanding the software requirements correct... » read more

Market Catches Up With Verification IP
By Ed Sperling - 23 Feb, 2012 - Comments: 0

By Ed Sperling Ever since verification IP was introduced it was seen as something that should be given away with purchased IP. The result was limited investment by IP vendors, frustration on the part of IP customers, and a market opportunity that nearly fizzled before it even began. But as the amount of commercially developed IP content continues to grow in ICs, the potential interactions ... » read more

Mechanical Meets Electrical
By Ed Sperling - 09 Feb, 2012 - Comments: 0

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 - 09 Feb, 2012 - Comments: 0

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 Ed Sperling - 09 Feb, 2012 - Comments: 0

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

A Brief History Of Power Formats
By Barry Pangrle - 09 Feb, 2012 - Comments: 0

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
