Integrated logic circuit

Abstract

Abstract PURPOSE:To realize the simplification of the individual process by a method wherein the connection of between plural logic circuits is carried out through a first common wiring system and a second proper wiring system of derivative kind peculiarity and the first wiring system is used as the bidirectional base wiring. CONSTITUTION:A wiring of part (a) is mainly used as a bidirectional base wiring which is able to receives and sends a signal between plural logic circuits. (b) is a logic circuit part with plural function block in a integrated circuit composed of the master slice method, and its input and output part is simply composed of an input and output buffer, a 3-state and a bidirectional buffer etc. (c) is a wiring system to connect derivative kind peculiarities between the logic circuit part (b) which contains plural function blocks and the bus type wiring system (a), and is used as normal wiring, which propagate a signal to the single direction, or bidirectional wiring, according to the character of a terminal of the logic circuit (b).
