Abstract: A method of predicting semiconductor device failure rate and an electronic device for performing the method are provided. The method of predicting semiconductor device failure rate includes receiving schematic data for a unit circuit in a first circuit and layout data corresponding to the schematic data, generating, by at least one processor, a netlist based on the schematic data and the layout data, performing a first simulation on the layout data to generate first simulation data for a test point of the layout data corresponding to a first node in the netlist, applying the first simulation data to a second simulation for the first node to generate second simulation data regarding whether the unit circuit is in fail operation, and calculating a failure rate for the first circuit based on the second simulation data.
