Abstract

PURPOSE: To heighten measurement accuracy, by obtaining the compensated data of a standard sample from a value measured by a sampling oscilloscope and another value measured by a function LSI tester, and by compensating the measured value of a measured device by said compensated data.
CONSTITUTION: The input and output pins of a standard LSI sample 4 are connected to a sampling oscilloscope 7 and a function LSI tester 8. Lag times are measured in each test pattern with regard to each combination of the input and output pins. The measured lag times are stored on discs 9, 10. The difference between the lag times stored on the discs is calculated. Such calculated differences are stored as a compensation table showing a measured unit difference, on another disc 15. The input and output pins of a measured LSI13 are connected to the function tester 8. Lag times are measured in each test pattern with regard to each combination of the input and output pins of the measured LSI13. The measured lag times are compensated in each test pattern with regard to each combination of the input and output pins, by a compensator 16 on the basis of the compensation table stored on the disc 15.
