Overview
AEi Systems is a specialized electronics engineering practice founded in 1995 as Analytical Engineering. It focuses on worst-case circuit analysis (WCCA), SPICE modeling, signal and power integrity analysis, radiation analysis, reliability, and stress and derating analysis. The practice serves space, aerospace, automotive, medical, and commercial electronics programs. It maintains proprietary parts-variability databases, radiation aging data, and in-house testing facilities to deliver rigorous, independent evaluations.

Services
Worst-Case Circuit Analysis (WCCA)
Rigorous electrical analysis of circuit designs under extreme and end-of-life operating conditions to identify potential failures before manufacturing.
Signal Integrity Analysis
Evaluation of high-speed digital boards to ensure signal quality, timing margins, and minimal noise.
Power Integrity Analysis
Analysis of power distribution networks, sequencing, and noise to guarantee stable voltage delivery to critical ICs.
Stress and Derating Analysis
Component-level stress verification to ensure all electronic parts operate within established guidelines under worst-case load conditions.
Radiation Analysis
Work in this area is organized into supported delivery tasks.
Reliability and FMEA/FMECA
Systematic assessments of electronic system reliability, failure modes, and mission risk factors.
SPICE Modeling
Creation, correlation, and validation of accurate component models for electrical simulation platforms.
RF and Power Systems Analysis
Analysis of radio frequency circuitry and power-system designs for satellite, aerospace, and medical programs.

AEi Systems' Design Review saved us a great deal of money and design iterations by identifying EOL issues before PDR!
AEi Systems enables us to save on costs by providing us with on-demand qualified professionals seasoned in circuit design and worst case analysis.
AEi Systems' WCCA is the gold standard!
AEi Systems' response time and experience helped put our project back on track.
AEi Systems' models provide exceptional results. Their models correlate consistently with our hardware!
AEi Systems' converter analysis meet or exceeds all of our expectations.
AEi Systems is an invaluable resource. The AEi Systems engineers quickly achieved expert-level knowledge of the design and operation of our high-performance space-qualified rubidium frequency standard and helped us close out all remaining component electrical stress and end-of-life circuit-stability design matters within the required deadlines.
AEi Systems met and exceeded our delivery timeframe and results expectations and was an asset throughout the entire critical design review process. With the dedicated effort of the AEi Systems team, we were able to meet our commitments to ITT, Lockheed Martin and the U.S. Air Force.
AEi Systems has proprietary relationships with nearly all of the top analog IC manufacturers. Those relationships give AEi access to the part characteristics needed to produce models with the accuracy our customers expect
