Abstract

A computerized method for automatically generating a grid-based derivative of a non-gridded cell library of an integrated circuit design comprises the step of determining at least one valid position of at least one wiring element of a circuit of the first cell library, wherein the at least one valid position fulfills all technological design rules and wherein the at least one valid position fits into the second grid format. The method can also be used for automatically transforming a first cell library of an integrated circuit design having a first grid format into a second cell library having a second grid format or for automatically analyzing a grid-based cell library of an integrated circuit design in view of the circuit quality regarding technical design rules.
