Patent ID: 7634391

Claim:
An IBIS correction computation apparatus converting IBIS data provided for a specific power supply voltage for a specific semiconductor device to corrected IBIS data corrected so as to match with a desired power supply voltage different from said specific power supply voltage for said specific semiconductor device, comprising: a data input unit for reading all data for an electrical characteristic of an output of said specific semiconductor device defined by said IBIS data as numerical data consisting of x-y coordinates; a correction coefficient calculating unit for calculating a relative ratio of said numerical data of the x-y coordinates read at said data input unit for said specific power supply voltage and numerical data represented on the same x-y coordinates for said desired power supply voltage as a correction coefficient; and a corrected IBIS data generating unit for converting IBIS data corresponding to said specific power supply voltage on said x-y coordinates to said corrected IBIS data corrected so as to match with said desired power supply voltage.
