Abstract

PURPOSE:To contrive a shortening in the development period of an integrated circuit and a reduction in the cost of the integrated circuit by a method wherein the connection between the elements or between the gates of such the integrated circuit as a gate array and a PLA is designed so as to be able to perform on the side of users using a simple device. CONSTITUTION:A coupling circuit 1 consisting of a wiring and transfer gates is provided between input/output terminals i/o1, i/o2,...i/on of an integrated circuit and internal gate circuits G1, G2,...Gn of the integrated circuit. The above terminals i/o1-i/on respectively can be connected to their desired circuits G1-Gn through this circuit 1 and at the same time, the fellow circuits G1-Gn can be connected arbitrarily to one another through this circuit 1. At the time of rise of a system, a control circuit 3 reads out ON and OFF information from the interior of a memory 2 and feeds the information to a transfer gate to correspond to the information in the circuit 1 and a desired input/output terminal and a gate circuit and the fellow gate circuits are connected to each other. Thereby, the integrated circuit performs an operation based upon a designed logic.
