Cell, standard cell, standard cell library, a placement method using standard cell, and a semiconductor integrated circuit

摘要

A cell according to the present invention comprises a plurality of terminals capable of transmitting an input signal or an output signal and serving as a minimum unit in designing a semiconductor integrated circuit, wherein the plurality of terminals is located on routing grids lined in a Y direction which is a direction vertical to a power-supply wiring of the cell used in automatic placement & routing and has a shape extended in an X direction which is a direction in parallel with the power-supply wiring, more specifically such a shape that, for example, a longer-side dimension of the terminal is equal to “a routing grid interval in the X direction+a wiring width. According to the constitution, a cell area is reduced, which advantageously leads to the reduction of a chip area.
