摘要： First of all, a given logic circuit is divided into a combinational circuit portion and a register portion. The combinational circuit portion obtained by division is divided into a plurality of partial circuits having high connectivity. Each partial circuit is converted into a circuit having the transistor level. Then, a layout cell of the partial circuit having the transistor level is generated. Thereafter, arrangement and wiring are performed by using, as unit cells, a layout cell which corresponds to each register included in the register portion and the layout cell for each partial circuit in the combinational circuit so that a block layout is created. Accordingly, a layout having excellent characteristics can be created by a few kinds of cells in both circuits having the CMOS logic and the pass-transistor logic. In particular, the partial circuits having high connectivity are arranged in a cell in the circuit using the pass-transistor logic. Consequently, the optimum driving capability can be obtained and the layout having stable characteristics can be created. In addition, it is possible to ensure the superiority such as a reduction in area, the low consumed power, high-speed operation and the like.

Standard cell rows are arranged in a vertical direction, each standard cell row including standard cells arranged in a horizontal direction. In the standard cell rows, positions of the N well and the P region in the vertical direction are switched every other row. Adjacent standard cell rows share the P region or the N well. A distance from a PMOS transistor located at an end of a standard cell row to an end of an N well is greater than or equal to a width of an N well shared by standard cell rows.
