1. A system for qualifying a logic cell library which qualifies a new library and a modified library, the system comprising: a format transformer for transforming formats of the new library and the modified library into formats suitable for a predetermined qualifier; a sample generator for creating a qualification cell sample capable of qualifying all cells by using cells of the new or modified library having a transformed format; a cell matching tool for performing a one-to-one cell comparison between cells of the new library and cells of an existing library; a function qualifier for determining whether or not a right value is output with respect to an input value in order to qualify a cell function of the new or modified library; a processing rate qualifier for measuring a time required from signal input to signal output in order to qualify a cell processing rate of the new or modified library; a power consumption qualifier for measuring power consumed during a process of a cell of the new or modified library; and an inter-qualifier for determining whether or not logical design information and physical design information of the new or modified library suitably corresponds to each other.
