DesignCon panel to look at measurements and simulations
From October 2012 to October 2013, I was the Editor-in-Chief of DesignCon Community, the predecessor of EDN's DesignCon Central. During that time, I conversed with many DesignCon regulars about simulations and measurements relating to high-speed serial data streams. Coming from the measurement side, I was fascinated by the simulations engineers do to predict how a board, circuit, or system will perform before building it.
During an interview with Scott McMorrow of Teraspeed Consulting, I asked "What do you do when the measurements don’t match the simulations?" Scott then spent the next half hour explaining all the things that can go wrong in both the simulations and the measurements. Following that education, the proverbial light bulb went off and I realized we had the basis for a panel discussion at DesignCon 2014. Finding other panelists was easy. Closing the loop: What do we do when measurements and simulations don't match? will take place Thursday, January 30 from 3:45 PM to 5:00 PM in the Santa Clara Convention Center. The panel will consist of:
- Scott McMorrow, President, Teraspeed Consulting Group who will lead off with a slide about using measurement feedback to improve solver accuracy.
- Steve Pytel, Signal Integrity Product Manager, ANSYS will follow Scott by discussing why you need to understand about how test equipment and simulation tools work, including assumptions made when using them.
- Yuriy Shlepnev, President, Simberian will then make recommendations on what to do when you don’t have a match between measurements and simulations.
- Doug Burns, VP & Chief Scientist, SiSoft will explain what to do when the board you receive isn't board you designed. He'll discuss designed dimensions versus actual dimensions, dielectric surface, roughness, and plating issues.
- Jason Miller, Hardware Development Manager, Oracle will explain how to weed out bad measurements or simulations.
- Alfred Neves, Chief Technologist, Wild River Technology will close the presentations by discussing the workflow involved in opening the eye.
Following the presentations, we will open the floor to questions from the audience. You can beat the rush by posting your questions for the panel in comments below.
