Filed: 1999-11-29
Abstract: PURPOSE: A boundary scan test circuit of a semiconductor device is provided to prevent a ground bounce and a clock waveform degradation generated during not only a boundary scan test operation using a JTAG circuit but also a normal operation, by varying a circuit of a boundary scan register inserted into all the input/output cell of a simultaneous switching output block. CONSTITUTION: Cells(60) comprises the fifth and the sixth multiplexer(62,66) and the third and the fourth D flip-flops(64,68) between an input terminal and an output buffer(70). And, a delay circuit(80) adjusts a clock signal of blocks(90) and supplies it so that it switches N bit output terminals simultaneously and outputs them. The fifth multiplexer is comprised between the input terminal and the third D flip flop and receives an input signal and a shift driving signal from the input terminal and a cell in a former stage during a normal operation and a test operation. The third D flip flop is comprised between the fifth multiplexer and the sixth multiplexer, and outputs data to the sixth multiplexer by receiving an output signal of the fifth multiplexer and a clock driving signal from the cell in a former stage. The sixth multiplexer is comprised between the third D flip flop and the fourth D flip flop, and receives the input signal from the input terminal during a normal operation, and outputs an output signal of the fifth multiplexer and the clock driving signal to the fourth D flip flop. And, the fourth D flip flop is comprised between the sixth multiplexer and the output buffer, and receives an output signal of the sixth multiplexer during a normal operation, and outputs data to the output buffer by receiving an update driving signal in a former stage during a test operation. Therefore, during a normal operation of the output terminal, data is transferred to the output buffer through the fourth D flip flop. And, an SSO(Simultaneous Switching Output) block is divided into several blocks, and delays a clock signal supplied to each block using the delay circuit.
