Abstract
A signal level adjustment system adjusting a level of signal outputted from a signal output circuit is realized. An input buffer threshold adjustment unit sets a threshold of a signal input circuit to a first variable value. A signal level adjustment unit adjusts an output level of a first signal at the signal output circuit until a voltage of the first signal outputted from the signal output circuit and inputted to the signal input circuit falls into a given range determined based on the threshold.
