Abstract
To reduce the time for verification in lithographic data and reduce the turn-around-time in preparation of lithographic data, a first lithographic input data and a second lithographic input data are compared in their data formats to extract data of the first lithographic input data excluding data common to the second lithographic input data as a first difference data, or to extract data of the second lithographic input data excluding data common to the first lithographic input data as a second difference data. If the first difference data and the second difference data contain data, they are compared graphically to extract different data as a third difference data. If the third difference data contains data, the first lithographic input data and the second lithographic input data are acknowledged to have a difference therebetween.
