The paper deals with the multiple soft fault diagnosis in analog circuits. The dictionary method for detection, location and identification of multilpe soft fault has been already presented. It is based on the node approach and one of the new evolutionary method – gene expression programming. In this paper the developing of the method with handling tolerances is presented. The proposed approach with taking into account tolerances is based on statistical analyses of circuit under test with different values of elements which are not faulty and also have not nominal values. The method is illustrated with an numerical example.
