Abstract: An electronic device configured to generate a verification vector for verifying a semiconductor circuit including a first circuit block and a second circuit block includes a duplicate command eliminator configured to receive a first input vector including a plurality of commands and to provide a first converted vector, in which ones of the plurality of commands that generate the same state transition are changed into idle commands, based on a state transition of the first circuit block obtained by performing a simulation operation on the first input vector, a reduced vector generator configured to provide a first reduced vector in which a number of repetitions of the idle commands included in the first converted vector is reduced, and a verification vector generator configured to output the first reduced vector having a coverage that coincides with a target coverage among a plurality of first reduced vectors as a first verification vector.
