摘要： Provided is a timing control device including: a storage unit that stores multiple pieces of timing control information including identification information and expected value data; a first selector that selectively outputs any of the multiple pieces of timing control information; a second selector that selectively outputs any of data items output from data output devices based on the identification information; a reference data generation unit that generates reference data based on expected value data and a data item output from the second selector in synchronization with a switching of the timing control information; a comparator that compares the reference data with the data item output from the second selector and outputs a coincidence signal when the reference data and the data item coincide with each other; and an output control unit that outputs a timing signal according to the coincidence signal.
