Tobi Delbruck from Zurich University, Switzerland, publishes a confession session "Lessons Learned the Hard Way" that he has organized at ISCAS 2020. Many of the confessions are related to the camera technology. Most of them are coverered in the video, but some appear only in the conference paper.
Various custom designs for various customers. It was painful to explain to customers as well as for cashflow. Not as painful as for the engineer who made the goof and then had to do a lot of dumpster diving - alas to no avail. All the early Photobit-ers know this story!
Very often, we can learn from our mistakes more than what we learn from our victories.
But in our culture, it's not common to talk about mistakes, it's much more common to talk about our successes. Can you publish a paper about a failed simulation, failed design, or failed chip?
A friend of mine, Ken Dyer, an experienced analog designer, has a blog, where he talks about his failures and his lessons:
Thanks very much for all the kind comments, but the big thanks should go also to Walter, Bernabe and Teresa who helped assemble the confessions and to all the fun contributions from people like Eric our students, and our many SSTC colleagues. And of course to JED Hurwitz who stimulated the first ISSCC forum on misteakes (sic) and to my father Max Delbruck for calling his group meetings "confession sessions", which I used to sit in on as a kid.
Some people might enjoy reading about those here; good taste of the old days in Caltech biology: https://books.google.ch/books?id=GcH1YyGiP3AC&pg=PA72&lpg=PA72&dq=max+delbruck+confession+sessions&source=bl&ots=O_BAjK3hVw&sig=ACfU3U3QMeeBAF5A3hm9AUtr8AYehALBSw&hl=en&sa=X&ved=2ahUKEwjEucyWw4bsAhVHi1wKHW7vD2sQ6AEwBnoECAYQAQ#v=onepage&q=max%20delbruck%20confession%20sessions&f=false
Love it! Great job Tobi! Loved your "confessions" sessions as well. Good stuff to learn from!
ReplyDeleteEric, just for curiosity, what was on the wafers that got thrown away?

DeleteThat's how you become an expert : you have to make all errors/mistakes/goofs first, and learn from it !
ReplyDeleteA very good paper!
