Abstract
Methods and systems for analyzing design of an integrated circuit are described. An example method includes receiving a design layout for an integrated circuit and forming a plurality of images of portions of the design layout. The method also includes, for each image of a portion of the design layout, calculating a Fourier transform representation of the image and extracting values of pre-defined parameters from the Fourier transform representation. The method also includes comparing the extracted parameter values of the plurality of images to create a clustering model by unsupervised machine learning and to sort each image of a portion of the design layout into a cluster defined by the clustering model. The method also includes determining a number of images sorted into at least one cluster defined by the clustering model.
