A gate array is a complex, pre-assembled logic circuit
whose logics and gates are linked together in a customer-specific manner. Most of the manufacturing steps of a gate array are customer-independent and standardized to a certain extent. For example, the location of the various gate circuits, AND gates, OR g ates or XOR gates, I/O pads, flip-flops, shift registers
, etc. is fixed. The customer can only influence the wiring of the logics.
