Abstract
A semiconductor integrated circuit device includes a standard cell having a plurality of height regions. A plurality of partial circuits having an identical function and each operating in response to common signals S and NS are arranged in any one of the height regions. A metal interconnect forming part of a supply path for the common signal S is arranged in the height region so as to be connected to the partial circuits, and a metal interconnect forming part of a supply path for the common signal S is arranged in the height region so as to be connected to the partial circuits.
Claims19
A semiconductor integrated circuit device comprising:
- a standard cell implementing a predetermined circuit function, wherein
- the standard cell includes
- N power supply lines (where N is an integer equal to or greater than three) including a first power supply line supplying a first power supply potential and a second power supply line supplying a second power supply potential, the first and second power supply lines extending in a first direction, and being alternately arranged in a second direction perpendicular to the first direction, and
- a plurality of flip-flop circuits each operating in response to one or more types of common signals,
- each of the flip-flop circuits is arranged in any one of M (where M=N−1) height regions each sandwiched between the first power supply line and the second power supply line,
- in each of first height regions, which are at least two of the M height regions, two or more of the flip-flop circuits are arranged and a metal interconnect forming a supply path for a first common signal, which is one of the common signals, is connected to at least two of the flip-flop circuits.
