Patent ID: 8495541

Claim:
A characterization device comprising: a characteristic value extraction unit configured to calculate a delay time at each measurement point within a hard macro and to extract characteristic values of the hard macro by applying a slew to a signal waveform that is inputted to the hard macro and making a static path search, the characteristic values including a setup time and a hold time of the hard macro; and a dynamic verification unit configured to verify whether the characteristic values are adequate or not by making a dynamic verification of the hard macro utilizing the characteristic values extracted by the characteristic value extraction unit, wherein the characteristic value extraction unit measures the delay times at a plurality of paths to the data holding circuit within the hard macro by applying a slew to the signal waveform that is inputted to the hard macro, makes a static path search, and calculates the setup and hold times of the data holding circuit from the maximum value and the minimum value of the delay time on the paths to extract the characteristic values.
