Hardware Fault Insertion and Instrumentation System: Experimentation and Results.

Abstract

This report describes the motivation, conduct, and analysis of some 2500 low-level hardware fault cases applied in automated testing at the NASA Ames Reconfigurable Digital Flight Control System (RDFCS) Facility. Fault detection was correlated with hardware and software fault monitoring, and in limited cases, with sensitivity to flight program execution modes. Results obtained have been statistically assessed to ascertain system-level reliability implications based on a model that is described herein. The overall methodology/facility itself has been critiqued and found to constitute a promising enhancement to current practice. Keywords include: Automated testing, Digital flight controls, Fault coverage, Fault latency, Fault modeling, Hardware Faults, Monitors, Statistical fault data.
