Automatic selection of test frequencies for the diagnosis of soft faults in analog circuits
Cesare Alippi, Marcantonio Catelani, Ada Fort, Marco Mugnaini · 2003
This paper addresses the problem of automated fault diagnosis in analog electronic circuits, based on Simulation Before Test techniques. The diagnosis is obtained by comparing the faulty circuit signature with a set of examples contained in a fault dictionary. A method for improving the fault dictionary is presented, based on a global sensitivity analysis method and on a fuzzy processing method applied to the obtained sensitivity curves.
