Abstract: A method for processing data containing information about an electronic circuit having a plurality of hierarchically organized networks is disclosed. The method involves processing the data which represent the circuit to be tested such that all the networks of the circuit are checked in hierarchical order for an association with a network type. If such an association is established, it is transferred to the data record for the network at the top of the hierarchy (i.e., top network). The association is then transferred to the data records for the subnetworks associated with the top network (in the opposite hierarchical order). The knowledge of the association between each network and the network type can then be used for a plausibility check of the circuit. Further, a computer readable storage medium and a data processing system contain computer-executable instructions for performing the method.
