Abstract

It is common to use ATPG of scan-based design forhigh fault coverage in LSI testing. However, significantincrease in test cost is caused in accordance withincreasing design complexity. Recent strategies for testcost reduction combine ATPG and BIST techniques.Unfortunately, these strategies have serious constraints.We propose a new method that employs ATE and BISTstructures to apply coded test patterns to LSI circuits.Results obtained using practical circuits show drastic testcost reduction capability of the proposed method.
