<P>PROBLEM TO BE SOLVED: To provide an emulator device for which the degradation and damage of an element are prevented without collisions of output signals with each other between a peripheral substrate and a center substrate while suppressing a cost rise. <P>SOLUTION: The peripheral substrates 10, 20, 30, and 40 of the same substrate size and wiring pattern or the like are allowed to output to the center substrate 50 and perform a normal operation in the case of deciding that authentication codes received from the center substrate 50 are the authentication codes suited to themselves, and turn output signals to a high impedance state in the case of deciding that the authentication codes received from the center substrate 50 are the authentication codes not suited to themselves. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
