Abstract
The provided are a don't-care-bit identification method and program for identifying don't-care-bits from the first and the second input vectors in an input-vector pair while keeping the sensitization status of paths, in a combinational circuit, sensitized by applying the first and the second input vectors in serial to input lines of combinational circuit. The method identifies an unspecified bit from the first and the second input vectors Vand Vcomposed of logic values 0 and 1, which are applied to the combinational portion in a sequential circuit or to an independent combinational circuit. The method includes an identification step for identifying an unspecified bit from the first and the second input vectors, while keeping sensitization status of a part of or all of the paths, sensitized by applying the first and the second input vectors.
