Patent ID: 6898545

Claim:
A semiconductor test data analysis system which automatically records operation information of an analysis operation, including analysis conditions or an analysis procedure for input test data, and analysis information obtained by the analysis operation, this system comprising: a processing means; an analysis target data storage means, for storing the test data as analysis target data; a historical data storage means, for storing as historical data at least one of operation information of the analysis operation or analysis information obtained by the analysis operation; a display data storage means, for storing analysis information obtained by the analysis operation and the operation information of the analysis operation, which stores analysis display data generated by the processing means; and a display apparatus for displaying at least one of a data window related to analysis target data stored in the analysis target data storage means, a history window related to historical data stored in the historical data storage means, a display window related to display data stored in the display data storage means, and a plurality of icons, which display or specify either operation information of the analysis operation or analysis information, wherein the plurality of icons includes one of: means for displaying or making a selection related to the analysis target data of the analysis operation, means for displaying or making a selection related to the operation information of the analysis operation, means for generating an indicator representing a relationship between the means for displaying or making a selection related to the analysis target data of the analysis operation and means for displaying or making a selection related to the operation information of the analysis operation, and means for displaying or making a selection for visually rendering analysis information of the analysis operation, wherein when a new analysis operation is specified, the processing means processes the input test data, the analysis target data, the historical data, and the analysis display data being processed by the new analysis operation for displaying at least one processed information relating to newly created analysis target data, historical data, and analysis display data.
