Computer program and apparatus for evaluating signal propagation delays

摘要

A computer executes a signal delay evaluation program to determine whether reference levels used to define slew rates of a first circuit block are different from those used for a second circuit block that receives an output signal from the first circuit block. The computer corrects an output slew rate of the output signal supplied from the first circuit block to the second circuit block, based on a difference in the reference levels that is found between the first and second circuit blocks.
