Abstract
A method includes identifying the first path as a target path, wherein an operation speed of the target path is adjusted from the corner case; deriving and outputting first values from the lookup table by indexing the lookup table with a threshold voltage associated with the first path identified as the target path as the main threshold voltage and a threshold voltage associated with the second path as the slave threshold voltage; calculating a first extra time based on the first values and first cell delays associated with the first path.
