Patent ID: 8229724

Claim:
A signal transmission system evaluation apparatus for evaluating a signal transmission system, the apparatus comprising: a processor; a memory storing executable instructions which when executed by the processor perform the functions of: a parameter acquisition section that acquires model information about a waveform simulation model of the signal transmission system, a first parameter of a waveform variation in a time direction in the signal transmission system, and a second parameter of a waveform variation in an amplitude direction in the signal transmission system; a first eye pattern calculation section that calculates a first eye pattern of the signal transmission system through a waveform simulation based on the model information acquired by the parameter acquisition section; a second eye pattern calculation section that calculates, based on the first and second parameters acquired by the parameter acquisition section, a second eye pattern through processing of the first eye pattern calculated by the first eye pattern calculation section; and a transmission margin calculation section that calculates, as a transmission margin, a positional relationship between a specific area and an aperture of the second eye pattern calculated by the second eye pattern calculation section.
