In this paper, a new approach to analog test design based on the circuit design process, called Characteristic Observation Inference (COI), is presented. In many situations, it is prohibitive to directly verify the circuit specifications due to the test equipment costs. Our approach considers a given universal set of reasonable input stimuli and measurements that can be performed with the given test equipment. From this universal set, a minimal number of measurements is automaticallyselected that represent a set of observations characterizing the state of the circuit under test with respect to parametric faults. A parametric fault model is introducedwhichis related tothe individualcircuit specifications. For each given circuit specification, a corresponding test inference criterion is computed, based on logisticdiscriminationanalysis. By applyingthese criteria, the satisfaction or violation of the given circuit specifications can be inferred from the observations of the circuit un...
