COMPARISON DEVICE AND METHOD FOR COMPARING TEST PATTERN FILES OF A WAFER TESTER

摘要

A comparison device for comparing test pattern files of a wafer tester includes a storage unit and a processing unit. The comparison device stores a first to-be-compared file and a second to-be-compared file into the storage unit. The processing unit reads the first to-be-compared file and the second to-be-compared file from the storage unit to process and executes comparison operation, so as to generate a comparison result. The comparison operation compares the words in a first section of the first to-be-compared file with the words in a second section of the second to-be-compared file in a one-to-one manner, wherein, if the first section ending point is not the end of the first to-be-compared file or the second section ending point is not the end of the second to-be-compared file, the processing unit resets the first section and the second section, and executes comparison operation again.

主权项

1. A comparison device for comparing test pattern files of a wafer tester, which is provided for comparing a first to-be-compared file with a second to-be-compared file, wherein the first to-be-compared file and the second to-be-compared file are text files, the comparison device comprising:
a storage unit for storing the first to-be-compared file and the second to-be-compared file; and a processing unit for reading the storage unit and processing and executing comparison operation for the first to-be-compared file and the second to-be-compared file to generate a comparison result, the comparison operation comparing words in a first section having a first section starting point and a first section ending point of the first to-be-compared file with words in a second section having a second section starting point and a second section ending point of the second to-be-compared file in a one-to-one manner, wherein, if it is determined that the first section ending point is not the end of the first to-be-compared file or the second section ending point is not the end of the second to-be-compared file, the processing unit resets the first section starting point, the first section ending point, the second section starting point and the second section ending point, and executes comparison operation again, and wherein locations of the first section starting point and the second section starting point are determined by the processing unit according to the comparison result and, if it is determined that the comparison result of the first to-be-compared section has a terminal inserting part, a reset location of the first section starting point is in the terminal inserting part and the word on the reset location of the first section starting point replaces the terminal inserting part.
