Abstract
A semiconductor integrated circuit capabling of reducing a chip area by facilitating optimization of a chip layout and a method for designing the same has been provided. For given gate level connection description, use cell information designating gates which should be designed by employing the cell patterns prepared in advance is generated. When the gate level connection description is developed into the transistor level, hybrid connection description including mixedly transistor level and gate level is then generated by employing the cell patterns relative to the gates which being designated by the use cell information and by developing gates which being not designated by the use cell information into transistor level. A layout is then designed based on the hybrid connection description including mixedly the transistor level and the gate level.
