AEi Systems is a space and power electronics engineering firm based in the United States that concentrates on circuit, systems and design analysis. AEi Systems is the world leader in Worst Case Circuit Analysis of critical space-bound circuitry, boards and components, including power supplies and power systems. Such specialized analysis often informs changes and updates to designs that have previously been deemed flght-ready. The company is well known for its deep analysis of space-bound DC-DC converters and other industrial and commercial power supplies and power systems — especially those that must operate reliably over long periods of time. Analyses often performed by AEi Systems include stress analysis, failure analysis, and reliability analysis, in addition to WCCA. AEi Systems also has significant digital analysis offerings and capabilities in signal integrity, power integrity, and Worst Case Digital Analysis. engineers are recognized by Aerospace Corporation as WCCA Subject Matter Experts. AEi Systems WCCA Subject Matter Experts worked with Aerospace Corporation to draft and set the current standards for WCCA of high reliability circuitry.
History
The company's predecessor, Analytical Engineering, Inc., was founded in 1995. The company met with significant early success as the developer of simulation models and performed Worst Case Circuit Analysis on the International Space Station's power bus electronics. A series of satellite projects continued to keep founder Steve Sandler and Analytical Engineering busy, including Tempo, Globalstar, GOES, GPS, MCI, Omegasat and P-81. In 2002, with the idea of expanding the business and the management team, the businesses of Arizona-based Analytical Engineering, Inc. and a related New York-based company, Analytical Services, Inc., were combined and purchased by AEi Systems, LLC and moved to Los Angeles in transactions spearheaded by Charles Hymowitz and his business partner, . AEi Systems continues to improve its capabilities and to set the standard for performance of Worst Case Circuit Analysis, stress analysis, failure analysis and reliability analysis. AEi Systems has also expanded its digital analysis offerings and capabilities to include performance of in-depth reviews and analyses of the signal integrity and the power integrity of identified circuitry, boards and systems. AEi Systems has senior engineers in several United States cities, including in a significant subsidiary engineering center in Los Angeles, California.
AEi Systems: Overview, Achievements and Projects
Divisions/Organization
The company has three, inter-related business lines:
Analysis: Worst Case Circuit Analysis, failure and reliability analyses; signal integrity, power integrity and other digital analyses.
SPICE Modeling: Modeling of complex integrated circuits for major IC manufacturers and to support AEi Systems' analysis efforts and reporting.
Software: Sale of licensed copies of the company's , and WCCA templates and tables.
Noteworthy achievements and facts
Motorola University's "six sigma class" on worst case analysis was created by AEi Systems.
Most SPICE models for rad-hard Power ICs available on the Internet were created by AEi Systems, including those found on the websites of ON Semiconductor and Texas Instruments and those used via National Semiconductor's online WEBENCH tool.
Many of the circuits and components analyzed by AEi Systems must keep within pre-set size and weight limitations and meet difficult "hi-rel" performance requirements at all times.
Defense and Aerospace Projects
AEi Systems has been involved in the development and analysis of some of the most sophisticated and technically challenging power systems in the world, both in the space and military defense arena and also with respect to commercial and industrial applications. The company provides computer simulation models and performs WCCA on most projects. Many of the company's projects are for United States "classified" programs. Among the company's publicly known projects are:
AEi Systems' deep circuit analysis and design review expertise has also been sought for commercial and industrial projects that do not involve space, military or defense. For example, AEi Systems has worked on:
AEi Systems has produced robust SPICE models for many major IC manufacturers, including Texas Instruments, ON Semiconductor, Analog Devices, Linear Technology and National Semiconductor. Since 2005, AEi Systems' modeling business unit has produced and internationally distributed its 600-model . The company has also developed a library of proprietary SPICE models to support its performance WCCA services and reporting.
WCCA Training and Support
The company developed and taught the "six sigma" WCCA training class for Motorola University, and continues to teach WCCA techniques via on-site classes for customers as well as several LA-based workshops.
