PROBLEM TO BE SOLVED: To provide a device which automatically generate a bus interface circuit while preventing registers or memories of the bus interface circuit form having the same addresses. SOLUTION: When data of a hardware description 10 are inputted to an extraction part 101, the extraction part 101 extracts from the data whether a storage element is a memory or an FF. When the storage element is a memory, the extraction part 101 reads in the head address and size, but when an FF, the address is read in and its data are outputted to an address conflict detection part 103. The address conflict detection part 103 detects a conflict of addresses by detecting whether 1 is stored as information of the address stored in a bit data storage part 102 according to the data outputted from the extraction part 101. Then an output part 104 converts the data of the address, etc., of the storage element outputted from the address conflict detection part 103 into the hardware description language of the bus interface circuit and outputs them.
