Abstract
An IC element layout data displaying system includes a magnetic disk unit for storing IC element layout data, and a preprocessor capable of reading the IC element layout data from the magnetic disk unit, of dividing the IC element layout data into a plurality of pattern sets each having an optional number of successive pieces of graphic information on the basis of the IC element layout data in the IC element layout data, and of generating map information including position information representing respective positions of pattern sets. A pattern retrieving unit accesses the IC element layout data by using the map information generated by the preprocessor to obtain graphic information corresponding a display area specified by an input unit. A display unit displays the graphic information retrieved by the pattern retrieving unit.
