Abstract: A semiconductor test data analysis system (1) automatically recording, during an analysis operation, operation information of the analysis operation, including analysis conditions or an analysis procedure for input test data, or analysis information obtained by the analysis operation. The analysis system includes a processing means (101), an analysis target data storage means (109), which stores the test data as analysis target data, a historical data storage means (107), which stores as historical data either operation information of the analysis operation or analysis information obtained by the analysis operation, and a display data storage means (112), which stores analysis information obtained by the analysis operation, which stores analysis display data generated by the processing means for the purpose of displaying the analysis information obtained by the analysis operation.
