Abstract
Methods and apparatus are provided for automatically extracting standard cells to form a standard cell library using raw multi-layer images of an IC. Accordingly, various embodiments involve: extracting the raw contact layer image from the raw multi-layer images; binarizing the raw contact layer image to generate a binarized contact layer image identifying a plurality of contact rows and a plurality of contact columns; determining a plurality of Vlines based on a subset of the plurality of contact rows having a periodic nature; extracting a plurality of binarized contact layer image strips from the binarized contact layer image; encoding each binarized contact layer image strip using feature vectors and column distance values; applying a model rule set to each encoded binarized contact layer image strip for detecting cell boundaries; extracting the standard cells based on the cell boundaries; and storing the extracted cells to form a standard cell candidate library.
