    摘要: A structure and method for identifying a physical location of a defect in a logic circuit based on a physical location of a logic latch having failing data. The logic circuit includes a plurality of logic latches, each having a predetermined physical location within the logic circuit. The logic latches are connected to devices adjacent the logic latches, such that the failing data in the logic latch indicates a failure of a device adjacent the logic latches.
