Architectural Layers & Protocol Stacks

Instruction Set Emulation & Virtualization (QEMU Aerospace Fork / SystemC TLM-2.0): Executing unmodified aircraft binary firmware with cycle-accurate register and memory timing.
Virtual Network & Bus Interconnect (Simulated AFDX / Virtual ARINC 429 Transceivers): Routing simulated packets between virtual LRUs with exact microsecond transmission delays and jitter.
Parallel Digital Shadowing & Comparison (State Machine Discrepancy Comparator): Comparing physical aircraft telemetry with virtual twin outputs, flagging unintended software drift or cyber tampering.
Post-Flight Debugging & Root-Cause Analysis (Deterministic Execution Replay / Time-Travel Debug): Allowing software engineers to step backward in time through CPU execution to pinpoint intermittent flight glitches.

Flight Telemetry Metrics: 100% (Binary Code Execution Parity) | < 1 Frame (Digital Shadow State Divergence Lag) | Time-Travel (Deterministic Microsecond Replay) | Zero Hardware (Requirement for Virtual Test Clusters)
