Inroduction
In the early days we made paper plots of an IC layout then measured the width and length of interconnect segments with a ruler to add up all of the squares, then multiplied by the resistance per square. It was tedious, error prone and took way too much time, but we were rewarded with accurate parasitic values for our SPICE… Read More
One of the first things that needs to be created when bringing up a new process is the Process Design Kit, or PDK. Years ago, back when I was running the custom IC business line at Cadence, we had a dominant position with the Virtuoso layout editor and so creating a PDK really meant creating a Virtuoso PDK, and it was a fairly straightforward… Read More
In part I of this series, we looked at the history of lithography process models, starting in 1976. Some technologies born in that era, like the Concorde and the space shuttle, came to the end of their roads. Others did indeed grow and develop, such as the technologies for mobile computing and home entertainment. And lithography … Read More
“Power is the new timing” has almost become a cliché. There are a number of reasons for this, not least that increasingly it is power rather than anything else that caps the performance that a given system can deliver. Power is obviously very important in portable applications such as smartphones because it shows through directly… Read More
The earthquake and subsequent tsunami that devastated Japan on March 11[SUP]th[/SUP], 2011 will have far reaching ramifications around the world for years to come. People have asked me how this disaster will affect the semiconductor industry so I will try and summarize it in this blog.
First the foundries:
According to TSMC: … Read More
Last week I met with Joseph Davis, Ph.D. at Mentor Graphics in Wilsonville, Oregon to learn about a new product designed for full-custom IC layout designers to improve productivity.
The traditional flow for full-custom IC layout designers has been nearly unchanged for decades:
This is just another blog about Carl Icahn and his quest to conquer EDA, when in fact EDA is conquering him. It includes highlights from my dinner with Mentor Graphics and Physicist Brian Greene, the Mentor Q4 conference call, and meeting Mentor CEO Wally Rhines at DvCon 2011.
It wasn’t just the free food this time, dinner with Brian… Read More
Abstract:
There has been a remarkable acceleration in the adoption of advanced verification methodologies, languages and new standards. This is true across all types of IC design and geographic regions. Designers and verification engineers are surprisingly open to new approaches to keep pace with the relentless rise in design… Read More
Multiple, independent clocks are quintessential in SoCs and other complex ASICs today. In some cases, such as in large communications processors, clock domains may number in the hundreds. Clock domain crossings pose a growing challenge to chip designers, and constitute a major source of design errors–errors that can… Read More
A growing number of reports highlight a class of design errors that is difficult to check using more traditional methods, and can potentially affect a wide range of IC designs, especially where high reliability is a must.By Matthew Hogan
Today’s IC designs are complex. They contain vast arrays of features and functionality in … Read More
