    摘要: A design support device having a permissible power supply fluctuation deriving unit and a target impedance deriving unit. The permissible power supply fluctuation deriving unit derives the fluctuation in the power supply voltage that is permissible on the basis of jitter-voltage correlation information, which indicates the correlation between the power supply voltage fluctuation generated in an I/O buffer and the jitter generated by the power supply voltage fluctuations, and jitter constraint information, which is for stably transmitting a signal, for the generated jitter. The target impedance deriving unit derives a target impedance in the permissible range of impedance for a power supply circuit, on the basis of information on the signal operating current flowing through the power supply circuit of the I/O buffer, and the power supply voltage fluctuation.
