Abstract:
1. A signal transmission system evaluation apparatus which evaluates a quality of a signal transmission system, the signal transmission system including a sending device, a transmission path, and a receiving device, the signal transmission system evaluation apparatus comprising: an acquisition unit which acquires statistics about a variation in a characteristic value and a limit value of the characteristic value corresponding to a given range of variation, with respect to each of a plurality of characteristic values which represent characteristics of the components; a probability distribution calculation unit which calculates a probability distribution with respect to each of the characteristic values, based on the statistics acquired by the acquisition unit; an eye-opening calculation unit which calculates an eye-opening of the signal transmission system in a case that the characteristic value is equal to the limit value; an adjustment unit which makes an adjustment of the limit value so that the eye-opening calculated by the eye-opening calculation unit satisfies a given eye-opening condition; and a yield rate calculation unit which calculates a yield rate of the signal transmission system, based on the probability distribution calculated by the probability distribution calculation unit and the limit value adjusted by the adjustment unit.
