Abstract
A method for detecting static-current failure devices in a chip is provided. The method includes providing a chip and determining existence of a static-current failure device in the chip. The method also includes detecting positions of a plurality of hotspots in the chip when the existence of the static-current failure devices is determined; and selecting a common circuit path according to position information of the hotspots in a circuit layout file of the chip. Further, the method includes converting a circuit layout of the common circuit path into a corresponding electrical diagram and marking the positions of the plurality of hotspots on corresponding positions on the electrical diagram; and detecting a shared device of the hotspots in the electrical diagram. Further, the method includes marking a position of the shared device in the circuit layout as a position of a static-current failure device.
