A semiconductor integrated circuit design apparatus includes: an association information creating unit which creates association information for associating wiring information of a signal line with wiring information of a shield line placed for the signal line; an association information storage unit which stores the thus created association information; and a shield wiring unit which, when the placement of the signal line is changed, changes in interlinking fashion with the changed placement the placement of the shield line that is associated with the signal line by the association information.

A logical-group creating unit creates a logical group from a cell included in a selected range of a logical drawing that is specified in a logical page. A logical-group extracting unit extracts a same/similar logical group by determining whether logical drawings of created logical groups are same or similar to each other. A pattern creating unit creates an implementation pattern of a logical group included in extracted same/similar logical group.

A semiconductor device including a logic circuit capable of decreasing a leakage current occurred during a standby state is provided. The semiconductor device includes a power supply portion for supplying a first operation voltage or a second operation voltage smaller than the first operation voltage; a P-type low-threshold transistor Tp for receiving the first or the second operation voltage from the power supply portion; and a N-type transistor Tn connected between the transistor Tp and a base potential. The transistors Tp, Tn construct a logic circuit. The power supply portion supplies the first operation voltage to the source of the transistor Tp in the enable state, and supplies the second operation voltage in a standby state. The second operation voltage is set so that voltage amplitude between gate and source of each transistor Tp, Tn is larger than the threshold value of the transistors Tp, Tn.
