A method of testing an integrated circuit on a functional block by functional block basis

摘要

A design for testability is applied so as to enable significant reduction in test time of an actual integrated circuit. First, an integrated circuit is full-scan designed on a block-by-block basis and test input patterns are generated (S11). Then, one of the blocks to which the design for testability has not been allocated is selected (S12), and a full-scan design is allocated thereto (S14). Test points are inserted into a block that has more than a prescribed number of parallel test input patterns when that block is full-scan designed (YES in S15) (S16).
