New SPICE Library for FORD Automotive EMC Transient Sources 

Attention WCCA Analysts – AEi Systems has released PSpice Model support for Ford’s FMC1278 Transient EMC sources, signal generators, and loads.

The models are included as part of the latest “Power IC Model Library for PSpice”, v4.3. Owners of the library will receive the models as part of their maintenance.

  • A PSpice model library for FMC1278 EMC Transient and ESD Sources and Loads is now available
  • Models are included for CI 210, CI 211, CI220, CI222, CI230, CI 250, CI 260, CI 280
  • Includes Pulses A1, A2, C1, C2 and Modes
  • Immunity, load dump, double battery, power cycling, voltage offset, voltage dropout
  • Other SPICE syntaxes are available. Please inquire for pricing
See the Power IC Model Library page, Power Library Brochure, and Version 4.3 News Release for more information and complete list of models in the library.


Do You Need Worst Case
Analysis Support?
AEi Systems performs WCCA for Automotive applications. If you are in need of this electrical engineering service, please contact us at 310-216-1144 or

Performing this analysis for the first time is not a trivial excersice. It is simply not for first-timers.
  • Having trouble figuring out what to analyze and navigating automotive WCCA Guidelines?
  • Don’t fully understand the scope and what is expected?
  • Having trouble figuring out how to model and simulate your circuit?
If you are interested in learning how to perform WCCA, the best way to do that is work with AEi Systems on your first WCCA. The process will result in an analysis you can use as a guide for future efforts.

BONUS: A copy of the PSpice Power IC Model Library (single license) is included with each WCCA we perform for you. This includes the FMC1278 model set, enabling you to perform EMC and ESD transient simulations.

AEi Systems brings decades of WCCA experience to bear on finding problems in your circuitry. We highlight the worst case issues and provide the reporting auto manufacturers are looking for. We help you fix the issues we find and our WCCA passes muster with manufacturer review teams and industry standards.


Automotive WCCA
Training Class Announced

AEi Systems will hold its popular 2-Day WCCA Training Workshop (for Automotive Applications) on June 26th & 27th in Detroit Michigan. Sign up NOW while spots are available!

Course Syllabus

This course provides the perfect opportunity to learn about worst case circuit analysis, its methods, and its processes. The course is designed to provide the participant with the fundamental skills and knowledge required to perform a Worst Case Circuit Analysis (WCCA or WCA). Participants learn the importance of this analysis and the different methods which can be utilized. The course concentrates on Automotive topics and producing WCCA for automotive applications. 


How WCCA Saves Money and Schedule 

“The Case for Worst Case”

There are many reasons to do worst case circuit analysis, apart from the obvious reliability improvement, or the fact that an analysis is simply a contractual requirement. All of them save money and schedule by helping to reduce design iterations, board spins, and other production missteps that contribute to cost overruns.

This article discusses the many ways in which WCCA saves money and schedule.

    Less expensive and more cost effective than in-house resources  
  • Our full-time team of top engineers with focused backgrounds in reliability, design, WCCA, and test has all the required core competencies to perform with great efficiency.
  • We have a significant number of SPICE models already made. We have Parts Variability Databases. We have Radiation Data. Even if you have in-house resources, dealing with models and tolerances can take a significant amount of time. AEi Systems puts the money and time savings in your pocket as we do not charge extra for this valuable IP.
  • Analysis is all we do; Keep your in-house designers doing what they do best. All our bids are Fixed Firm!

    Faster than in-house resources - ready to go 
  • Our proprietary software tools, library of proven SPICE models, and our 20 years of analytical engineering experience keep your team ahead of schedule
  • No bias - We introduce "checks and balances" to your design process/SDRLs
