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

Joe Davis Now that almost all of the major custom design tools run on OpenAccess, we often get asked about how well Calibre supports OpenAccess (OA). The truth is that Calibre has supported reading polygonal data from OA since February 2007 and we have kept up with the new releases of OA as they come along. What has really driven adoption of OA in the last year or so has been the release of Virtuoso on OA, the … Read More

Waive Bye-Bye

Posted by John Ferguson

John Ferguson In my last post I discussed the reasons and challenges associated with “waivers” for DRC.  As discused, this is becoming a bigger and bigger challenge as designs become more intricate and design rules become more complex.  To the poor design team that has the challenge of integrating IP from multiple sources into a single working design, this can become a nightmare to manage.  Not only is the DRC debug … Read More

Joe Davis DAC is less than two months away… and the phone is starting to ring again…saying “We are doing demos and realize that we are showing Calibre everywhere. Do you want to participate in our demos?” Of course we do Our approach has always been to make Calibre available in every design tool and on every database. This approach is good for everyone.  Designs have to be certified “clean” (more on that in … Read More

Source Netlist Creation for LVS

Posted by Matthew Hogan

Matthew Hogan Hopefully you’ll find the current and future content posted here interesting enough that you’ll come back and share own opinions, thoughts and ideas. Please let me know if there are specific topics you’re interested in. Maybe we can look at these in the future… Today, I’d like to explore the task of creating a trusted source netlist that is used as the template for comparison to prove that your layout … Read More
