Bottom-up approach to system life estimation, integrating lab validation, statistical models, and industry standards.
From big machines to small handheld equipment, all typically come with varying warranty timelines based on estimations. If this number is overestimated or underestimated, it can incur millions of dollars in losses to manufacturers. That’s why it’s important to look at the lifetime system estimation as a bottom-up process. The efficiency in this approach results in a robust method to formulate the top-down design flow of a system that can operate reliably over the required duration. The design method can guide a system designer at every design step to make the right decisions regarding electrical component choice as per the ratings, electromechanical component choices, such as crystal oscillators, component placement, trace thickness, copper imbalance, and operating conditions.
