Abstract

An integrated circuit includes a test pattern input unit for inputting a test pattern into cells, a clock distributing unit for distributing a clock signal to the cells, a first cell that receives the clock signal distributed by the clock distributing unit, a second cell that receives the clock signal after the clock signal is received by the first cell, a data transfer unit for transferring a data signal from the first cell to the second cell, a clock transfer unit for distributing the clock signal to the first cell and the second cell and transferring the clock signal in the same direction as the transfer direction of the data signal, and a failure detecting unit for inputting the test pattern into the cells and detecting failures of the cells on the basis of the results of the test pattern output from the cells.
