ABSTRACT:
Operation cycles to be subjected to an IDDQ test are selected from among operation cycles defined by a test pattern for a functional test of a CMOS integrated circuit so that a sufficient and necessary number of operation cycles are accurately and rapidly selected. A combination of sets of m-bit data are selected so that the combination includes sets of m-bit data each bit of which is changed from one of the values "0" and "1" to the other at least once. The operation cycles corresponding to the sets of m-bit data included in the combination are rendered to be the IDDQ test cycles to be subjected to the IDDQ test.
