The d.c. fault dictionary approach has been found very useful for diagnosing hard failures (open circuits and short circuits) in non‐linear analogue circuits. In this paper we present the use of several techniques to enhance the capability of the d.c. fault dictionary. These include (1) modelling all non‐linearities by piecewise linear characteristics, (2) solving the piecewise linear resistive network by Lemke's complementary pivot algorithm, (3) using multilevel logic operation to compile an integer‐code fault dictionary which totally eliminates any post‐test calculations. the automatic generation of a fault dictionary for a video amplifier by the use of the computer program HAFDIC is described.
