Abstract
A semiconductor integrated circuit design tool includes a reference data defining module configured to define design data of one of a plurality of transistors implementing the semiconductor integrated circuit as reference data, a simulator configured to simulate each effective channel length of the transistors, based on the design data and a reference channel length based on the reference data, and an adjuster configured to adjust gate lengths of gate electrodes of the transistors to reduce a difference between the effective channel length and the reference channel length.
