Title CONVERSION DEVICE, CONVERSION METHOD, PROGRAM, AND RECORDING MEDIUM achieved
Abstract Provided are a conversion device and others for converting a test vector set so as to reduce a difference in logic values generated before and after a scan capture for output of a scan cell contained in a full scan sequence circuit. The conversion device (400) converts a test vector set corresponding to the full scan sequence circuit. The conversion device (400) includes: a setting unit (402) for setting a candidate bit which may be set to a don't-care bit according to a predetermined restriction condition based on I/O relationship in a logic circuit and a fixed bit which may not be set to a don't-care bit in order to specify the don't-care bit which may be set to don't-care bit from each test vector of the test vector set; and a logic value decision unit (404) for deciding the logic value to the don't-care bit by considering the relationship between a plurality of bit pairs for a test cube containing the don't-care bit identified by the setting unit (402).
