A fail analysis device enabling a simplified operation and a reduced operation time.. A reduced data acquiring section (40) reads a reduced logical data, obtained by reducing detailed logical data as a test result, from a CFM (120) in a semiconductor test device (100) and acquires it. A main viewer generating section (80) generates a main viewer window including a list of a test result for each DUT based on the reduced logical data for displaying on a display device (94). The list includes a result image indicating a pass/fail for each DUT and the reduced image of a fail bit map.
