ABSTRACT:
A method of finding a driving strength and a record medium accessible by a computer to store a program thereof are provided. The method is adapted to find the driving strength of an output pin of a target cell. Wherein, the driving strength of the output pin of the target cell is provided from the driving strength of a corresponding last level device. In this method, at least one candidate standard cell is searched in a standard cell library according to the last level device. Then, the driving strength of the target cell is interpolated between the driving strengths of the candidate standard cells to obtain the driving strength of the output pin of the target cell.
