Computer product, apparatus, and method for correcting time delay variation of a circuit design

摘要

A computer-readable, non-transitory medium stores therein a design support program that causes a computer capable of accessing a storage device storing therein for each cell, an output voltage value of the cell, for each elapsed time period from a start of variation of an input voltage applied to the cell, to execute a process. The process includes extracting from the storage device, the output voltage value for each elapsed time period related to an cell under design selected from circuit information of a circuit under design; determining based on a specific voltage value, an extracted elapsed time period to be corrected; adding a time constant of an output from the cell under design to the elapsed time period determined to correction; and outputting the output voltage value for each corrected elapsed time period and the output voltage value for each elapsed time period that is not determined for correction.
