BQR Fixtress

fiXtress

fiXtress is a superior Design for Reliability (DfR) suite, serving as an add-on for any Electronic Design Automation (EDA) tool. It is the only tool integrating design error detection with electrical stress, thermal, MTBF and service life prediction at the schematic level, before PCB layout and production. fiXtress modules can either operate standalone or complement other modules to provide a comprehensive DfR solution for electrical circuits and PCB design.

fiXtress includes the following modules

ASR – Automated Schematic Review

Rapid – Electrical Stress Calculation

Precise – Electrical Stress Simulation SDA – Stress Derating Analysis

MTBF – MTBF Prediction Mini Thermal – Average PCB heating Multi Board- System Level simulation G-Lib – Automated library preparation

Benefits

Automated Schematic Review tool; Detect hidden design errors, driven by Electrical Stress, Reliability, Testability and Safety analysis
fiXtress uses the ICD (interface Control Document) signals and their tolerance, this means we do a real stress analysis and schematic review based on the power supplies and loads
Single and Multi-Boards analysis using the ICD between PCBs, if you do not use the ICD it is not a real analysis
Ready to use 17 groups of design rules, each one about 15 sub-groups
User can define easily new design rules for different applications such as Testability, ESD and Safety (ready 56 rules)
Rules are not scripts which run individually one by one, fiXtress runs all rules together using the results effects between components
Advanced level of rules that can check group of signals & BUSs between chips
Check for every pin the applied actual voltage and current, that comes from a real stress analysis to fulfill the components standards
Prevent hidden design errors, the cause of NFF (No Failure Found) during service
Very fast and accurate results in minutes for hundreds of rules on a 100,000 pads PCB with 25,000 components
Ready to use derating standards
User can create his own derating standard
Detect all EOS (Electrical Over Stress) violations with Pareto, overstress and overdesign reports
Unique Thermal analysis that estimate the average temperature rise over the cold-plate, for accurate stress Derating
Calculate the accurate MTBF based on real electrical and thermal stress
MTBF prediction for all available standards
Drive reliability data automatically to all RAMS analysis (FMECA, FTA, RBD, MTTR)

Conclusions

fiXtress is a new EDA plug-In software to any schematic capture which helps the designer to detect hidden errors early in the design process. fiXtress is using an Automated Schematic Review method which is driven by electrical circuits stress analysis and a database of rules. A Rule Wizard Editor is available to add new rules. The Tool uses C++ and not scripts and run very fast on very large boards.

Furthermore, the fiXtress uses the power signals and the loads (ICD: Interface Control Document) from the connectors to perform real simulation as it is powered in real use, in comparison to other tools that do not use the ICD.
