Deterministic Time-Travel Debugging for Intermittent In-Flight Avionics Glitches
Core aerospace engineering and protocols for Time-Travel Debugging.
The Frustration of Transient Avionics 'Heisenbugs'
Some of the most dangerous aviation software bugs only trigger under specific timing alignments between asynchronous interrupts and multi-threaded tasks, disappearing whenever diagnostic logging is enabled.
Full-System Reversible Execution Replay
AvionicsDigitalTwins logs execution events deterministically: when an anomaly occurs in flight, the recorded trace is loaded into the virtual twin, allowing engineers to step backward in time, inspect register states, and identify the exact line of code that triggered the fault.
- Deterministic Execution Recording: Capturing all hardware interrupts, DMA transfers, and user inputs.
- Reversible Debugging: Stepping backward instruction-by-instruction to inspect corrupted pointers.
- Heisenbug Elimination: Guaranteeing that debugging does not alter execution timing.
- Rapid Root-Cause Isolation: Slashing investigation times from months down to hours.
