A semiconductor device includes a common bus (5) and a plurality of macros (1, 2, 3) connected in series by connections (L00, L01,..., L33). Each of the macros is constructed by an internal circuit (11, 12, 13), a buffer (12, 22, 33) connected between an input of the internal circuit and the common bus, a register (13, 23, 33) connected to the common bus, and a logic circuit (14, 24, 34) for selecting one of an output signal of the internal circuit and an output signal of the register. <IMAGE> |
