BQR Reliability Engineering Ltd.
BQR is a world leader in Reliability and Maintenance engineering for the electronic industry and provide add-on modules for the EDA market. BQR offers software tools that enhance, improve and optimize engineering processes in order to save costs and bring better, more robust, easy-to-maintain products to the market - faster. BQR’s solutions can be implemented for various scopes of projects, from Chip, PCB, Sub-System and System level up to asset/fleet levels.
BQR’s flagship product is fiXtress™ which includes Automated Schematic Review (fiXtress-ASR), Electrical Stress Analysis and Derating (fiXtress-ESA), MTBF and Life prediction. In addition, BQR’s CARE® Suite (Computer Aided Reliability Engineering) provides FMEA, Fault Tree Analysis (FTA), Testability analysis and Reliability Block Diagram (RBD) to optimize the amount of redundancy needed for high Availability.
CARE® comprises an integrated set of software tools, offering engineers a complete solution for all RAMS (Reliability, Maintainability, Availability and Safety) aspects of a product. CARE analyzes various component failures and their impact on system operational behavior and safety, while taking into account redundancy and backup elements. Unlike other tools, CARE provides all reliability analysis in one integrated platform – including traditional Mil-STD, ISO, EN and IEC standards methods and advanced RAMS & ILS analysis techniques. The use of BQR CARE improves and enhances product reliability and robustness. CARE features an extension to Altium and is integrated with Cadence and Mentor. CARE includes FMEA, FMECA, Fault tree analysis (FTA), Redundancy Block Diagram (RBD) and Testability (Built-in) analysis.
fiXtress™ Automated Schematic Review detects schematic design errors based on component parameters and good engineering practices defined by rules. Typical engineering practices result in a manual, complex design review process, and fiXtress ASR automates this procedure. It increases design efficiency, robustness and quality and verifies proper implementation of reference design as specified by the IC and ASIC manufacturers.
BQR’s fiXtress™ MTBF performs Mean Time Between Failure prediction and Component Electrical Stress Derating analysis. The MTBF module uses two methods: The first is Parts Stress using stress values such as power, voltage and current, which are automatically retrieved from fiXtress Rapid or Precise to calculate component failure rate based on stress. The second method is Parts Count, using a stress level of 50% as default, for MTBF estimation before performing Parts Stress analysis.
The software includes best practices for derating which helps create more realistic stress derating and component rating selection, increasing product robustness. The Stress Derating analysis includes a feature which estimates the average temperature rise of the PCB, even before layout, for an accurate stress derating analysis. With this information, the designer can select the proper size of the component rating, and place hot components in a cooler area. Additionally, assumptions can be made regarding required Air Flow (i.e. fan capacity) for reducing the temperature of the entire PCB.
fiXtress™ Precise is a comprehensive Design for Reliability (DFR) tool that optimizes the final design before production. BQR’s fiXtress Precise uses Kirchhoff laws for DC & AC stress analysis with an automated and innovative process, while accounting for component operation modes. The analysis results, including operational power, voltage and current are then fed to the MTBF Pro for electrical components derating analysis.
fiXtress™ Rapid is a simple, effective Design for Reliability (DFR) tool that accelerates and optimizes the design process. fiXtress Rapid enables the user to reduce development time by performing stress analysis during the design process. It helps select the correct component rating based on stress analysis. fiXtress Rapid uses Ohm’s law, propagating the voltage potential via all nets in order to calculate the operational DC power, voltage and current of each connected component. This method can be used even when the design is incomplete. The analysis results, including operational power, voltage and current are then fed to the MTBF Pro for electrical components derating analysis.
