<p>Provided are an operation confirmation test method, an operation confirmation test program, and a clock distribution circuit, wherein the operation confirmation test is possible in all adjustable phase ranges of a phase adjustment circuit, and the operation confirmation test can be performed easily and precisely. Disclosed is an operation confirmation test method wherein a computer performs an operation confirmation test of a phase adjustment circuit of a clock distribution circuit; the computer performing a first phase shifting step for shifting the phase of one of a first differential signal and a second differential signal with respect to the phase of the other signal; a first data acquisition step for acquiring a data signal of the differential (DFF) to which the first differential signal and the second differential signal having phases shifted in the first phasing step were input; and a first comparison step for comparing a plurality of data signal values with first expectation values of the plurality of data signals, wherein the plurality of data signal values are obtained by repeating the first phase shifting step and the first data acquisition step until the phase difference between the first differential signal and the second differential signal reaches an amount corresponding to one cycle of the first differential signal and the second differential signal.</p> |
