Analysis and Demonstration of Diagnostic Performance in Modern Electronic Systems
Abstract
This report presents methods and procedures for validation and demonstration of diagnostic system performance for use as part of the Government's acceptance test procedures for electronic systems having contractual diagnostic requirements. These methods provide for examining the adequacy of the diagnostics architecture, establishing bounds on fraction of faults detected (FFD) and fraction of faults isolated (FFI) (the only two figures of merit considered here), and choosing faults to be inserted in the demonstration, but fall short of confirming exact values for FFD and FFI. The current state-of-the-art does not support an exact determination of FFD and FFI for new equipment, especially that containing higher density VLSI and VHSIC electronic devices, because of the inability to determine the failure rates for the various failure modes, and the difficulty in inserting a truly random sample of faults.
