Abstract

PURPOSE:To automatically synthesize the logic circuit of a function module by inputting the specification of the function module, retrieving optimum information out of the information concerning the function module to be accumulated in a recording part and matching them. CONSTITUTION:Operation writing information 14, which show a relation among an input signal concerning a circuit to be desired to design, an inside condition and an output signal, are inputted from an input and output part 11. The operation writing information of the parts circuit of the circuit are stored to a storing part 18. A control part 12 includes a unification processing part 16 of an operation writing and an automatic synthesizing part 17 of the logic circuit. Then, by executing unification between one part of the operation writing of the circuit and one part of the operation writing of the parts circuit, a logical relation to include timing information is generated and based on the logical relation, a circuit to connect the interval of the parts circuit is automatically generated. Generated circuit information 15 are outputted to the input and output part 11.
