Jay Gorajia What if you had a tool that could prevent problems in your processes and products before they occur? Failure Mode and Effect Analysis (FMEA) is that tool.  FMEA is a formal process of identifying all the ways a process or product can fail, and then determining how to reduce or eliminate them. Product development groups and quality groups work tirelessly to identify ways their products and processes … Read More

IBM Addresses Leakage

Posted by David Abercrombie

David Abercrombie

In case you missed the webinar by Jim Culp on November 3rd, I wanted to give you an opportunity to see what you missed. Jim is a Senior Engineer in IBM’s Advanced Physical Design and Technology Integration team. He is leading a team in the development of Parametric DFM and the mitigation of Circuit Limited Yield (CLY). During the webinar he discussed how CLY is becoming the leading contributor to yield

20 Aug, 2009

David Abercrombie I got some questions from my last installment of this series asking for some pictures of defects that caused yield issues in production that could have been avoided during design. It struck me that most designers probably never get a chance to see the manufacturing problems their designs encounter. Since my background is in the fab, I wrongly assumed everyone had lived through the same pain as myself. … Read More

David's DAC09 - Lunch & Learn

Posted by David Abercrombie

David Abercrombie My Monday started off well delivering the eqDRC presentation with Jim Culp. But I didn’t have long to enjoy it as I had to quickly head up to the mezzanine level to get ready for my lunch and learn event with ARM and Chartered. We have had a long relationship with both companies and we finally arranged to do a joint presentation on how we have collaborated to make more DFM compliant IP. It started … Read More

David's DAC09 - White Paper Session

Posted by David Abercrombie

David Abercrombie I felt privileged this year to get a paper accepted into the technical track at DAC. It seems more and more difficult to get something through. I think they said they only had a 20% acceptance rate this year. I was glad to get to present this one because it was fun doing the experimentation for it and I think it helps answer one of the nagging questions I always get about eqDRC. I worked with Fedor … Read More

David's DAC09 - Off to a great start!

Posted by David Abercrombie

David Abercrombie Well it felt familiar to be back in San Francisco for DAC this year. However, I wasn’t ready for the cold. It was 100 degrees in Portland when I left and I always assume the Bay area will be warmer. Luckily I looked at the weather map before I finished packing and replaced my short sleeve shirts with long sleeve ones. I didn’t get in until late Sunday night so I only had time for a dinner in the Westin … Read More

To Waive Or Not To Waive?

Posted by David Abercrombie

David Abercrombie That is the question! If you read my colleague John’s most recent posting “Waive of the future?”, you will understand the question. I was equally shocked as John to find that almost no one tapes out DRC clean anymore. I would add one other reason to John’s list as to why this has happened. I think the traditional DRC rules are broken. Please read my first post “Are Design Rules Broken?” for my stance … Read More

David Abercrombie One of the fundamental questions everyone asks about DFM is “why should I do it?” On the one hand this always strikes me as a funny question. I always look at DFM in the same way I think of automobile safety. Statistically, most people never get in a serious accident. So why would you spend so much money on airbags, antilock brakes, better seat belts, side door reinforcements, traction control, etc. … Read More

DFM for Non-PhDs

Posted by David Abercrombie

David Abercrombie

I got a kick out of Rohan’s comment on my previous blog (How do you define DFM?).  It is too easy to assume that anyone knows what you are talking about when you say DFM.  Just because everyone has been talking about it doesn’t mean any of them know what they are talking about. You could probably infer from my approach to the previous blog that my background is primarily on the manufacturing side.

How do you define DFM?

Posted by David Abercrombie

David Abercrombie What does design for manfuacturing (DFM) mean to you? “More work to do!” “Someone else’s problem!” “Just more design constraints!” “The fab guys are expecting me to understand the process as well as design!” I propose that we define DFM (design for mfg) as an attempt to trasfer a way of doing business that has been tried and tested in the manufacturing space for years, into the design space. The fabs … Read More
