PROBLEM TO BE SOLVED: To inspect an input-output interface easily and quickly by avoiding the limitation of asynchronous or high speed inspection at the time of inspection of the high speed LSI. SOLUTION: A specific simple data inputted from an LSI inspection device 101 is converted by an encoder 104 into a complicated data, which is transmitted from a transmission LSI 102 to a receiving LSI 107. In the received LSI, the received data is decoded by a decoder circuit 109. The decoded data are a simple data, so the expected value is easily determined by the LSI inspection device 101. At the time of inspecting a high speed LSI, the input-output interface is inspected easily, in a short period of time by avoiding the limitation by asynchronous or high speed.
