All kinds of logic dircuits which are used in high density integrated circuit are composed of the sequential logic circuits.
The sequential circuit are installed the memory elements, and the memory elements are feed back to the combinational circuits. The memory elements are a device in which the binary information can be stored, and it shows the state of the sequential logic circuit.
The output of the sequential logic circuit is the function according to the present state of the memory elements, and it also shows state of the external input.
In this paper, we anslyzed the composition of the sequential logic circuit and proposed that the necessity of decision of the input pattern for the fault detection by the investigating the relationship between the input and output of the circuit in the case of the failure.
