Fully automatic DC fault dictionary construction and test nodes selection for analogue fault diagnosis

Although the Fault Dictionary (FD) is one of the oldest approaches in analogue fault diagnosis, it is the most used in industrial environments. We present a fully automatic system that selects a minimum set of test nodes and gives the range of their voltages for each fault. All the information it uses is in three input files given by the test engineer: the circuit description (similar to the SPICE), the fault list and the tolerance file. >
