Challenges of Automotive WCCA (Worse Case Circuit Analysis)

Want your module to be designed into tomorrow’s automobiles? Worst case circuit analysis (WCCA) is no longer optional. It’s now mandatory for compliance with automotive vendor requirements and various ISO standards. And for good reason. WCCA is a proven gateway to reliability. But undertaking WCCA is no joke. Product managers greatly underestimate the effort and the cost.

WCCA is NOTHING like MTBF or FMEA. It is FAR more complex. The scope of the work – what analyses to perform - is almost never defined. And once their defined what does it take to complete them within a tight schedule and with the resources/budget you have.

If this analysis is in your future, whether as a manager or analyst, this talk by Charles Hymowitz, a WCCA SME, is for you.

What you will learn:

  • What it takes to get a passing grade, within schedule and budget
  • What analysis tasks, resources, skills, time, level of rigorousness will be required to pull off an acceptable WCCA
  • Why testing isn’t an alternative and doesn’t indicate how well you’ll do in a WCCA
  • What’s the difference between stress analysis and WCCA and how do they work together
  • Scoping and costing a WCCA for Automotive Applications
  • What is the #1 problem facing designs today?
  • How tools like PSpice enable effective and accurate analysis for essential elements of a complete WCCA
