    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.

    摘要: The present invention provides a data path circuit layout design method capable of generating a mask layout which satisfies timing specifications and given contour conditions, and which is reduced in circuit area. There are prepared function macros in each of which there is defined an expansion, according to the parameters, to a circuit comprising a plurality of schematic leaf cells. For a data path circuit of which function blocks are described by function macros, the placement of the function blocks is optimized by a function macro placement process. By a function macro expansion process, the function macros describing the function blocks are expanded and connection information on the schematic leaf cell level are prepared. By a detail placement and routing process, the schematic leaf cells are replaced with the corresponding layout leaf cells and the layout leaf cells are wired to one another, thereby to generate a mask layout of the data path circuit.
