An apparatus for extracting design and layout information from image-mosaics of a progressive deconstruction of a semiconductor integrated circuit (IC) includes a visual display, a system pointer and a plurality of lockstep cursors. The visual display displays views of an area of interest of the respective image-mosaics. Each view displays one of the lock-step cursors when appropriate, as determined by a position of the system pointer. When the system pointer is within a view, a corresponding lock-step cursor is displayed as a master-cursor, while other views display a lock-step cursor that has a different size and shape than the master-cursor. All lock-step cursors move in unison under the control of the master-cursor. A method for extracting design and layout information from image-mosaics uses the lock-step cursors to quickly match features across image-mosaics, and to avoid transposition errors while tracing features from one image-mosaic to another.
A man-machine interface for analyzing image-mosaics, the image-mosaics being scaled and aligned to a sample coordinate space, the man-machine interface comprising:
A method of analyzing image-mosaics, the image-mosaics being scaled and aligned to a sample coordinate space, the method comprising steps of:
The method as claimed in clam 25 further comprising a step of selecting the image-mosaics to be displayed in mosaic-views of the area of interest from a list of all image-mosaics associated with the slice.
