Abstract
A method is provided. A library associated with a cell is received. A minimum setup time of the cell is acquired in response to an ideal hold time according to the library and a reference clock. A maximum hold time of the cell is acquired in response to the minimum setup time according to the library and the reference clock. A plurality of candidate hold times are determined. A plurality of candidate setup times are acquired corresponding to the plurality of candidate hold times according to the library and the reference clock. The plurality of candidate setup times are added to the plurality of candidate hold times, respectively, to obtain a plurality of candidate time windows. A target time window is selected that has a minimal time span among the candidate time windows.
