Problems solved by technology

However, because the I / O pad 20 cannot be overlapped with the corresponding I / O unit 18, the I / O pad 20 will occupy an additional layout area, and even become a dominant factor in the overall area of ​​the chip, so that the area of ​​the chip cannot be reduced.

Embodiment Construction

[0049] Please refer to figure 2 ; figure 2 It is a schematic diagram of an embodiment 30 of the input / output unit of the present invention. The layout of each circuit in the I / O unit 30 can be accommodated in a main area 26, and has a plurality of I / O ports (IOport); figure 2 In the embodiment, two input and output ports P1 and P2 are taken as an example to illustrate the present invention. The I / O ports P1 and P2 are disposed in the main area 26 and correspond to the same I / O pin 28 , so that the two I / O ports P1 and P2 can both transmit the I / O pin 28 signal. The I / O ports P1 and P2 may respectively correspond to a predetermined area A1 and A2. Wherein, each preset area A1, A2 can respectively accommodate an I / O pad, and among the preset areas A1, A2 corresponding to the I / O ports P1, P2, at least one preset area will be in the same shape as the main area 26. Partially overlapped. exist figure 2 In the embodiment, the two preset areas A1 and A2 partially overlap wi...

Abstract

The invention provides a multi-output-and-input-port output and input element which can save layout area and a method that realizes the manufacturing of a chip. The output and input element is provided with a plurality of output and input ports which can transmit signals of the same IO pin; every output and input port can respectively provide a corresponding preset area for containing one IO pin; and at least one preset area overlaps with active circuit layout area of the output and input element partly. In the chip, if the IO pin preset area of a given output and input element overlaps with the IO pin position of the neighboring output and input element, the preset area can be left vacant and a preset area corresponding to another output and input port is chosen from the given output and input element to realize the IO pin, thus ensuring that the output and input elements can be arranged more closely and saving the layout area of the chip.

Description

technical field [0001] The present invention provides an I / O unit with multiple I / O ports that can save layout area and its manufacturing method, especially relates to a device that can select and use different I / O ports in adjacent I / O units to set I / O pads to save chip layout area I / O unit and related technologies. Background technique [0002] Integrated circuit (Integrated circuit) is the most important hardware foundation of modern information society. In order to make the use of integrated circuits more popular, improving the integration of integrated circuits and reducing the size of integrated circuits has become the focus of modern integrated circuit design, manufacturing and research and development. [0003] Please refer to figure 1 ; figure 1 A schematic diagram (and a top view of portions thereof) of a conventional integrated circuit 10 is shown. In the integrated circuit 10 , a chip (chip / die) 12 is packaged on a packaging substrate 14 to form a complete in...
