1. A transmission path design assistance system comprising:
acquiring circuitry to acquire reflection specification values of a reflection characteristic of a transmission path to be designed and a constraint of characteristic impedance distribution of the transmission path; and
computation processing circuitry including:
reflection characteristic calculating circuitry to calculate the reflection characteristic from inputted characteristic impedance distribution;
reflection characteristic modifying circuitry to modify, on the basis of the reflection specification values acquired by the acquiring circuitry, the reflection characteristic calculated by the reflection characteristic calculating circuitry;
characteristic impedance distribution calculating circuitry to calculate characteristic impedance distribution from the reflection characteristic modified by the reflection characteristic modifying circuitry; and
characteristic impedance distribution modifying circuitry to modify, on the basis of the constraint acquired by the acquiring circuitry, the characteristic impedance distribution calculated by the characteristic impedance distribution calculating circuitry and output the modified characteristic impedance distribution to the reflection characteristic calculating circuitry.
