ABSTRACT:
Variable current sources (10a-10c) limit a value of current in each of standard cells (2a-2c) depending on a bias voltage given from a bias voltage generating circuit (11) whereby driving capability of each standard cell is limited. As a result, in both cases where the maximum load capacitance in practice is smaller than the load capacitance assumed at the time of designing, and where each standard cell is operated at a lower operation speed than the speed assumed at the time of designing, waste of power consumption can be avoided and noise can be reduced.
