PROBLEM TO BE SOLVED: To perform connection check successively from the high-order hierarchies by using physical and logical connection check among terminals of a circuit block in circuit design. SOLUTION: In a top-down circuit design, a definition slip of the circuit block in a top level is input by a user (S1). An attribute of the terminals of the circuit block in the top level is also included. Next, a circuit block in a first hierarchy to be a low-order hierarchy just under the top level is divided and the definition slip of the divided circuit block is created/input by the user (S2). An attribute of the terminals of the circuit block of the first hierarchy is also included in the definition slip. Then, the connection check between the top level and the first hierarchy is performed by a computer (S3). In this connection check, matching check for the attribute of the circuit blocks in the top level and the first hierarchy is also performed, in addition to the check of the presence/absence of connecting destinations for the circuit blocks in the top level and the first hierarchy.
