Abstract:
1. A system for qualifying a logic cell library, the system comprising: a format transformer transforming a new library into a format suitable for a predetermined qualifier; a sample generator creating a qualification cell sample capable of qualifying cells of the new library; a cell matching tool performing a one-to-one cell comparison between cells of the new library and cells of an existing library and, if a mismatched cell of the new library does not exist in the existing library, updating the existing library by obtaining the mismatched cell from a cell bank; a function qualifier 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 library; a processing rate qualifier measuring a time required from signal input to signal output in order to qualify a cell processing rate of the new library; a power consumption qualifier measuring power consumed during a process of a cell of the new library; an inter-qualifier determining whether or not logical design information and physical design information of the new library suitably correspond to each other; and a qualification library storing the new library qualified by the function qualifier, the processing rate qualifier, the power consumption qualifier, and the inter-qualifier.
