Abstract
Methods and apparatus are disclosed for rapid and interactive 'warping' of a first image made up of pixels to form a resulting image made up of pixels which are aligned, pixel-for-pixel, with a second image made up of pixels. The images may be stroboscopic voltage contrast images representing operating states of two integrated circuit devices--a failing device and a fully functional device. The aligned images permit an engineer who may have little knowledge of the device to diagnose dynamic failures of the failing device by comparing the aligned images to produce an image showing the differences.
