Abstract

See full text

Together with circuit data of circuit elements, there is stored, in a memory device, external specification information of each of the circuit elements, the information including (i) function information of each of the terminals of the circuit elements and (ii) selection information representing a wiring condition for each of the terminals. When the element arrangement and external specification information of a circuit to be designed, are entered, pieces of external specification information are compared with one another to obtain pairs of wiring candidates of a circuit which connects, to one another, the circuit elements of the circuit to be designed. Based on the pairs of wiring candidates, there is generated wiring information which satisfies each wiring condition. Based on the pieces of wiring information thus generated, there are automatically generated circuit data of the circuit to be designed.
