Analysis is critical to product performance, quality, and mission assurance. There are many reasons to perform it.

You know you need to do more analysis. But there's never enough time, money, resources, or schedule. Let AEi Systems tackle your analysis challenges.

Worst Case Circuit Analysis

Comprehensive analysis to identify and eliminate potential design flaws under worst case conditions, ensuring robust and reliable designs.

Power Integrity Analysis

Analysis of power distribution networks, VRMs, target impedance, and decoupling to ensure stable and reliable power delivery across your system.

Signal Integrity Analysis

Analysis of signal transmission paths, interconnects, timing, interface compatibility, and PCB layout to ensure minimal distortion, noise margins, and reliable high-speed data performance.

Stress & Derating Analysis

Evaluation of component electrical and thermal performance under various stress & derating conditions to ensure reliability and longevity in demanding environments.

Reliability Analysis

MTBF (FIT-Rate) and Failure Mode Effects (FMECA/FMEA) assessments to Mil Standards, by experienced experts, get this analysis completed quickly and accurately.

Radiation Analysis

Assessment of circuit and component susceptibility to radiation effects (SEE, SEU, SET, TID, DD) for space and missile missions.

PCB Layout Services

Design and optimization of printed circuit board layouts to ensure signal integrity, power distribution, manufacturability, and compliance with industry standards for reliable electronic performance.

Expert Review Services

WCCA and stress report reviews, CID+ PCB Layout reviews, and early-stage design reviews to catch issues before formal WCCA, saving time and cost.

Training

Workshops and training on WCCA to empower your management and design teams with the skills needed for effective analysis and analysis review.

We are Faster

We have historical Parts Variability databases along with radiation and aging data. We have data that is hard to find. In addition, we have our own in-house testing facilities.
We are the world’s leading expert in SPICE/ADS modeling and have many of the simulation models already built for commonly used SPACE parts. AEi Systems is the company that makes models for TI, Analog Devices, and many others. We have proprietary agreements and can get data others can’t.
We have created our own proprietary software to greatly speed up Sensitivity, Signal Integrity, and Stress & Derating analyses.
Analysis is never performed by a single person. It’s always performed by a team of experts with experience in key WCCA disciplines (Tolerances, Modeling, Test, Mathematics, Simulation, etc.)

We are More Accurate and Rigorous

Analysis is what we do. It is our core competency and we do it every day. We have been doing WCCA for over 30 years and count as our repeat customers top-tier players such as Boeing, Northrop Grumman, Lockheed Martin, Raytheon, Honeywell, L3/Harris, Ball Aerospace and many others.
Our staff has decades of satellite/aerospace and automotive experience in power, linear, RF, and digital circuitry.
Less is missed the first time, saving you iterations and schedule.
We help FIX the findings and issues we discover.

We are Independent

Let’s face it. Companies, programs, and engineers have biases. Schedule, time, and corporate pressures force a biased result. The design suffers.
As discussed in the Aerospace TOR on WCCA, independence is key to preserving the checks and balances that make WCCA valuable.
Because of our efficiency we can do more in the time and budget allotted. You end up with more findings caught and fixed.
