A process for a prognosis of faults in electronic circuits identifies parameters of a circuit under test. An upper and a lower limit is determined for one or more components of the circuit under test. A population of faulty and non-faulty circuits are generated for the circuit under test, and feature vectors are generated for each faulty and non-faulty circuit. The feature vectors are stored in a fault dictionary, and a feature vector for an implementation of the circuit under test in a field operation is generated. The feature vector for the implementation of the circuit under test in the field operation is compared to the feature vectors in the fault dictionary.
