<p><P>PROBLEM TO BE SOLVED: To determine the state of a tap controller at the time of logical simulation, even if there is no TRST as the external terminal of a semiconductor integrated circuit. <P>SOLUTION: A tap controller 2 has a reset terminal (terminal p4). A circuit 3 receives a state control signal for controlling the state transition in the tap controller 2, and a clock signal, and then determines the state of the tap controller 2 by supplying a reset signal to the reset terminal p4 according to the state control signal and the clock signal. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
