Time-Saving Features for Safety Analyses of Electronic Circuits

At BQR, we are constantly striving to enhance the workflow of safety and reliability engineers conducting safety and MTBF (Mean Time Between Failures) analyses. By collaborating closely with our customers, we have identified several time-consuming tasks that can be automated to improve efficiency.

Here are our latest software innovations designed to save time in your safety analyses:

MTBF Calculation

Calculating the failure rate (FIT rate) is essential for identifying the primary causes of product failures and serves as the foundation for FMECA (Failure Mode, Effects, and Criticality Analysis). BQR’s MTBF software simplifies this process by providing key component data with a direct link to datasheets at the click of a button. Once the component parameters are defined, they are saved in a library for easy reuse in future projects.

FMEA/FMECA – Functional Analysis

To determine the failure rate of a function in an electronic circuit, components must be assigned to each function. This can be time-consuming, especially in circuits with thousands of components. BQR’s FMEA/FMECA software offers a streamlined approach, allowing users to quickly select components on the schematic and assign them to their respective functions.

FMECA – Component Level Analysis

During component-level FMECA, component failure modes and ratios can be automatically assigned from established failure mode libraries, significantly speeding up the analysis process.

Testability Analysis (BIT Plan)

For mission-critical systems, designing Built-In Tests (BIT) requires ensuring that major failure modes are detected and that effective failure isolation is provided. BQR’s software facilitates quick assignment of tests to failure modes (based on FMECA), identifies critical functions that lack testing, and calculates detection and isolation effectiveness.

Schematic Review (Design Rule Check)

While schematic review is not traditionally linked to safety, it plays a critical role in identifying and eliminating design errors that may pose safety risks. BQR provides patented software for advanced schematic review, allowing users to detect design errors related to safety and reliability, as well as deviations from best practices.

Conclusion

BQR’s software solutions streamline the safety analysis process, centralizing all safety-related data and significantly reducing the time required for analyses. By implementing these innovative features, engineers can enhance their product designs while ensuring compliance with safety standards.
