Formal verification and safety case construction for converged communications and radar sensing hardware in autonomous automotive vehicles.
Combining radar and communications creates shared hardware dependencies. ISACSafe employs physically isolated clock trees and decoupled analog power planes to ensure RF synthesizer faults cannot blind both functions simultaneously.
All DSP signal processing pipelines are compiled using safety-qualified toolchains with ISO 26262 TCL3 qualification, backed by formal mathematical proofs of bounds checking and bounded worst-case execution time (WCET).
Extensive hardware-in-the-loop fault injection across 10,000 simulated collision scenarios demonstrated zero false-negative brake triggers and zero missed critical obstructions under extreme downpours and sensor vibration.
