| Software | Use it for | Bring to an evaluation | Review the outputs |
|---|---|---|---|
| Synthelyzer® ECAD Plugin | Schematic-stage reliability checks within your ECAD workflow, with design data supplied to other BQR tools. | Your ECAD tool and version, schematic and BOM, operating environment and required checks. | Component overstress findings, schematic rule violations, estimated assembly MTBF and initial FMEA data. |
| CircuitHawk™ | Circuit simulation and schematic verification, including connectivity and operating stresses across boards. | Schematic and BOM data from Synthelyzer, operating conditions, board interconnections and company review rules. | Rule violations, pin-level findings, overstress flags and component power dissipation. |
| fiXtress® | Component derating and MTBF prediction for electronic boards and systems, using operating stress and temperature. | Schematic/BOM export or Excel input, component parameters, operating conditions, derating rules and prediction method. | Derating and overstress reports, early thermal estimates, MTBF results and failure-rate contributors. |
| CARE® | System RAMS analysis: FMEA/FMECA, fault trees, reliability block diagrams, diagnostics and repair. | Product structure, component or assembly failure data, mission profile, repair assumptions and existing worksheets. | Failure-mode reports, critical items, fault-tree cut sets, reliability, availability and maintainability or testability metrics. |
| apmOptimizer® | Maintenance, repair-level and spare-stock planning for assets and fleets, comparing cost and availability. | Asset structure, failure and repair data, maintenance tasks, costs, spare-part lead times and availability targets. | Life cycle cost breakdowns, maintenance intervals, repair-policy comparisons, spare-stock levels and downtime metrics. |

How do the electronics and system tools work together?
Synthelyzer supplies design data from ECAD. CircuitHawk provides circuit simulation and operating-stress results; fiXtress uses stress and component data for derating and MTBF prediction. CARE carries reliability and failure data into system FMECA, fault-tree and reliability-block-diagram models.
When should I start with the free MTBF calculator?
Use the online calculator for field-data analysis or MIL-HDBK-217F2 parts-count prediction from a BOM. Evaluate fiXtress when you need component operating-stress analysis, derating, early thermal estimation or additional prediction methods.
What should we confirm before choosing modules and licenses?
Define the engineering decision, required standard and edition, input data, users and expected reports. The five products above are deployed on premises. Confirm the exact ECAD environment where relevant and walk through a representative project before choosing the module and license scope.
