| 摘要 |
A semiconductor integrated circuit apparatus relates to a structured ASIC that wires functional cells in a common wiring layer, which is not dependent on a user circuit and common to several sorts, and a customized layer provided over the common wiring layer to form the user circuit. In the semiconductor integrated circuit apparatus, a functional cell constituting a sequential circuit such as a flip-flop and a functional cell constituting a combinational circuit are placed in matrix of column and row. Further, the functional cell constituting the sequential circuit is placed obliquely in the matrix.
