Abstract
Design data of a cell group is copied to obtain design data of an antecedent cell group and of a subsequent cell group. Design data of a combinational circuit is copied to generate the combinational circuits in plural corresponding to a given number of cycles n (n=2, 3, 4 . . . , where n=3 in FIG.). The design data of the combinational circuits are connected in series between the design data of the antecedent cell group and the design data of the subsequent cell group. As a result, design data of an input constraint circuit representing an input constraint(s) of the circuit can be generated.
