Abstract
A semiconductor test system which generates a test pattern produced based on data resultant to device logic simulation performed on a computer for an LSI device designed in an electronic design automation (EDA) environment, tests the LSI device, and feedbacks the test results to the EDA environment. The semiconductor test system includes an event file for storing event data obtained by executing device logic simulation in a design stage of an LSI device under test; an event memory for storing the event data from the event file relative to timings; means for generating a test pattern by directly using the event data from the event memory and applying the test pattern to the LSI device under test; a result data file for evaluating a response output of the LSI device under test and storing resultant evaluation data; and means for evaluating design of the LSI device based on the data stored in the result data file.
