PROBLEM TO BE SOLVED: To provide a unit cell of a semiconductor integrated circuit by which wiring efficiency can be improved when the unit cell is used to arrange functional circuit blocks, and to provide a wiring method using the unit cell and a wiring program. SOLUTION: Auxiliary power wiring area TA2a to TA2c are formed in a unit cell 2 with a reference of grids which are provided in the X direction from the side of the cell at every basic cell width BCW. Input signal terminal AT2 to DT2 and an output signal terminal YT2 are arranged in a manner to have at least one wiring connection part outside the auxiliary power wiring area TA2a to TA2c. Thus, wiring other than the signal wiring can be connected to the auxiliary power wiring area TA2c. The unit cells are arranged like a matrix to form a functional circuit block 20, thereby forming the auxiliary power wiring area at a pitch of the basic cell width BCW to penetrate the functional circuit block 20 in Y direction.
