TIMING ANALYZER, TIMING ANALYSIS PROGRAM, AND TIMING ANALYSIS METHOD

摘要

A timing analyzer comprises an acquisition section for acquiring information on paths in an integrated circuit in descending order of a path having the largest propagation time, a path performance distribution calculating section for calculating path performance distribution which is the distribution of the performance of the path on the basis of the path information, an integrated circuit performance distribution calculating section for determining first calculated path performance distribution as integrated circuit performance distribution which is the distribution of the performance of a chip and performing the statistical max operation of first integrated circuit performance distribution which is last calculated integrated circuit performance distribution and the path performance distribution calculated by the path performance distribution calculating section to obtain the result of the operation as second integrated circuit performance distribution, and an evaluation section for instructing to repeat the processing of the acquisition section, the processing of the path performance distribution calculating section, and the processing of the integrated circuit performance distribution calculating section until a parameter indicating the difference between the first integratedcircuit performance distribution and the second integrated circuit performance distribution satisfies a predetermined condition.
