These defects are found while conducting internal testing, resulting in multi cycles of root causes, corrective action and verification. This can create unexpected developmental cost, program delays and missing the market window of opportunities. Or, even worse, product defects can be found by your customers, thus inflicting great warranty costs and damaging your company’s reputation.
The Solution – BQR One Stop Shop Complete Suite
The solution for eliminating design errors can be illustrated by the BQR fiXtress DFR Model which begins from the ground up. The DFR Model is built layer upon layer which support robust and bug free electrical circuits.
The first step, Schematic Stress Simulation aims to eliminate electrical and stress errors during the schematic design stage. The BQR software suite was primary developed to simulate components stresses (i.e. P, V, I, Tj). Its capabilities are to conduct Stress & Derating Analysis on any circuit schematic size (i.e. from hundreds of pads to tens of thousands of pads) & any type of electrical circuit (e.g. Analog, Digital, RF, or Power) at the schematic level before layout and production. Thus, there is a high level of flexibility for improving the design with lower costs than fixing product defects after First Article Tests.
Second step, MTBF Part Stress uses the simulated stresses to gain electrical circuit reliability with more accurate and realistic MTBF predictions thus enabling to root out the weakest links of the design that cause poor performance and high failure rates.
Third step, FMECA & TA, furthermore, enhances the electrical circuit reliability by predicting critical failure modes in advanced and thus can mitigate technical risks discovered by FMECA, following with Testability Analysis for defect detection coverage and defects isolation.
Fourth step, FTA, prevents safety hazards much required by Defense, Aerospace and Automotive or any critical industry. This brings the design to the next level of enhancing availability with RBD modeling redundancy, and boosting revenue using APM to reduce cost from operating and maintenance optimization.
The BQR DFR tools can work individually and self-contained, but also via one common core database that enables the tools to interact with each other allowing for seamless cooperation. The tools allow for the reuse of the results from one simulation to other analysis providing better accuracy and saving significant time. Thus, it is a simple way to allow for design modifications to be updated instantaneously for all simulations and analyses results.
BQR can help you improve product reliability and reduce time to market
