Abstract
Engineers usually compare circuit layout schematics by themselves in design stage. However, with the semiconductor technology improvement, the more and more complex PCB design has caused people unable to quickly check the layout by human eyes.n this thesis, we try to analyze the schematic automatically by image processing technology to reduce the mistakes and save a lot of time. o elaborate, this study applies the image processing technology to complete the layout tracking, distinguish each line by different colors with labeling algorithm, and analyze drill type by pattern recognition and morphological operations. In the end, we can get the connectivity of each layer of the layout image, and get the relationship of components by using SUSAN algorithm to recognize the footprints.est result show that our method can track the netlist through every layer correctly. It can also recognize basic components like resistors and capacitors.
