ABSTRACT:
A semicustom made integrated circuit is fabricated from first function blocks completed before acceptance of an order from a customer, second function blocks completed after the acceptance of order, input/output buffer circuits coupled with the first function blocks, buffer circuits respectively associated with the second function blocks, and controlling circuits provided in association with the buffer circuits for shifting the associated buffer circuits between input buffer circuits, output buffer circuits, bidirectional buffer circuits and three-state buffer circuits, and the controlling circuits are instructed by the second function blocks while the manufacturer is designing the wiring arrangement of the second function blocks so that the manufacturer does not need to individually tailor the wiring arrangement between the second function blocks and the associated buffer circuits.
