Goooaaaaaaaaaaaaal!

Posted by Shelly Stalnaker

Shelly Stalnaker The World Cup is here! Every four years, the culmination of hundreds of qualifying matches around the world brings the best national teams together for nearly a month of intense competition to determine the world champion football team (Sorry, USA, but it’s football everywhere else). New national uniforms are unveiled, shoe companies vie to sponsor the best players and teams with their most advanced … Read More

Paul Johnston   When engineers design products – and electrical systems on transportation platforms are no exception – the process inevitably involves checking. Checking the elements of the design are all present and correct. You may be testing the systems behave to anticipated norms. You may be looking back to the requirements, the specifications, looking over the shoulder to where the design work … Read More

Paul Johnston Let’s look briefly at cause and effect. In previous notes on this subject, I remarked choices between in-sourced or outsourced information technology solutions in an electrical design processes yield consequences .  What’s in it for you? Knowing more about these issues will inform your choices.  A common way of referring to a tangle of human-factor issues is to say decisions are “political.” Radical … Read More

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 - 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 - Another Special Guest

Posted by David Abercrombie

David Abercrombie Well, day two of DAC started a little earlier than the first day. I had to attend the speakers breakfast for the paper I was going to give later that day. However, after breakfast I had my 9am suite presentation on eqDRC again and I also had a special guest again. This time it was Robert Boone from Freescale in Austin, TX. He works in the DFM team and he also agreed to come tell everyone what he and … 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

Are Design Rules Broken?

Posted by David Abercrombie

David Abercrombie

It is no mystery that the number of design rules has exploded over the past few technology nodes. It’s impossible for any human designer to “remember” them all, much less follow them all. It’s also a problem for the CAD engineer. We extracted some data from a spectrum of DRC decks that our customers have in production and the graph below shows the results. DRC Rule Count and Complexity by Technology

Paul Johnston How soon out of date our foolish notions.  How persistent our tastes and allegiances. One of the suggested topics in the first post is now no longer relevant, fading swiftly as topical.  Pick one of the other ones.  Not number 6 - time and events have already overtaken it. How true the Robert Burns proverbial line about nest building rodent mother - there’s a Mothers’ day reference in honour or honor … Read More
