Shelly Stalnaker Remember learning your colors in kindergarten? Learning how to debug color assignment errors in multi-patterning can sometimes seem just as confusing. In Take Two of the Tech Talk videos on multi-patterning, David Abercrombie continues his discussion with Brian Bailey of Semiconductor Engineering about color assignment issues, and possible corrective actions. More often than not, a color assignment … Read More

Old Faithful

Posted by Shelly Stalnaker

Shelly Stalnaker While unpredictability may account for the lure of gambling, reliability is an essential part of our everyday lives. Yellowstone National Park, which sits above the Yellowstone Caldera, contains half of the world’s geothermal features. Among the most famous is Old Faithful, a huge geyser that erupts at regular intervals. One reason tourists flock from all over the world to this park is that they know … Read More

FinFET Fever...or FinFET Fear?

Posted by Shelly Stalnaker

Shelly Stalnaker All the major foundries have announced FinFET technologies. FinFETs hold the promise of lower power usage and better area utilization, as well as traditional scaling improvements. Aaaaand…the thought of implementing them may be scaring the willies out of a lot of designers. How do I design these things? How do I know what the design needs? How do I verify them? Well, first, take a deep breath. … Read More

How Do I?

Posted by Shelly Stalnaker

Shelly Stalnaker It happens all the time, to all of us. You need a quick answer for a very specific question about using your EDA tools. You don’t want to wade through technical documentation, you don’t have time for an email response, and you really don’t want to try searching EDA forums for an answer. We feel your pain, and we decided to do something about it. Need to know how to extract a net from … Read More

Shelly Stalnaker No one wants to edit a foundry rule deck—it’s like tugging on Superman’s cape. But there are many ways to customize the input to a Calibre job without modifying the foundry rule deck. To learn more, watch one of our short, to-the-point How-To videos on our IC Nanometer Design channel on YouTube. Oh, and if you can’t find what you’re looking for? Suggest a new topic! … Read More

Shelly Stalnaker Personal GPS systems were a blessing for directionally-challenged people. Model-based hinting (MBH) for LFD hotspot corrections evoke a similar feeling of relief in engineers who are tired of late-night stints trying to figure out how to correct a litho hotspot without creating even more problems. MBH can evaluate your fix options and identify which ones are viable, helping you make better decisions … Read More

Enabling Superior Support

Posted by John Ferguson

John Ferguson In my last few posts, I began discussing on what it takes to enable software quality and support.  This particular post will focus on the latter, support. Of course the goal of any descent software provider is to deliver software that is bug free, intuitive to use, and performs a valuable service.  While we strive for perfection, in reality these goals can never be fully achieved.  In the EDA world, … Read More

Assuring Software Quality

Posted by John Ferguson

John Ferguson In my last blog I discussed the importance of support and the value it provides in the physical verification space.  As indicated, one of the key components in providing support is having an infrastructure helps to assure quality software releases in the first place.  In this blog, I will provide more insight into the procedures in place within the Calibre organization that help to ensure the high standards … Read More

The Value of Support

Posted by John Ferguson

John Ferguson When asked about the value that the Calibre platform brings to the design community, most folks will respond with performance, foundry support, and ease of debugging. While these are all valuable aspects and traits of Calibre, there is one more benefit that is often taken for granted: support. The word “support” is something bandied around loosely in EDA. Saying you have good support is akin to saying … Read More

John Ferguson I don’t normally take the time to respond to any of the various competitive claims out there. But recently in ESNUG 483, item #2, there was a posting entitled “We recently dumped Mentor Calibre for Magma Quartz DRC/LVS” (http://www.deepchip.com/items/0483-02.html) that I feel needs to be addressed because it is misleading. So let me lay out the facts to set the record straight. Tezzaron Semiconductor … Read More

Joe Davis Recently, I attended the latest OpenAccess (OA) conference put on by Si2. Attendance this year seemed to be up from last year. Whether the increased attendance was due to the increased adoption that we’ve seen in the industry or the fact that the conference was free this year is unclear. However, it is crystal clear that OA is no longer just a promise, and that adoption has moved from the true early … Read More

The Biggest Loser?

Posted by John Ferguson

John Ferguson A new season of NBC’s “The Biggest Loser” recently started. Have you seen this show? My wife, Cherie, loves it; she finds it inspirational to watch these folks put them through such a tough ordeal in order to improve their health. I enjoy it as well, though my motives are completely different. There are some pretty large individuals on that show. Somehow watching them makes me feel less self-conscious … Read More

ESD Design Rule Checking

Posted by Matthew Hogan

Matthew Hogan Verification of ESD structures and other protection circuits is often a time consuming and tedious task. How do you do it? Complex DRC rules? An assortment of specialized rule decks? Home-brew tools? Recently a colleague and I published a paper which used one of the Mentor tools (Calibre® PERC) to help with this ESD checking. If you’re interested, the paper is available on-line here: New Flow for … Read More
