Apparatus and method of supporting design of semiconductor integrated circuit

A design supporting apparatus for a semiconductor integrated circuit, comprises:

• a cell data generating section configured to generate a data indicating a basic cell and a data indicating each of cells of a cell group different in logic from said basic cell;
• a library;
• and
• a library building section configured to store the data indicating the basic cell and the cells of the group cell in said library,
• wherein an outer shape and a wiring pattern position in each cell of said cell group is same as those of said basic cell,
• each of a wiring pattern in said basic cell and a wiring pattern in each cell of said cell group comprises a wiring obstruction section to show an area in which a passage wiring is inhibited,
• when a design change is carried out, said basic cell is replaced with a change cell of said cell group in response to said design change.

A computer-readable recording medium in which a computer-executable program code is stored to realize a method of supporting design of a semiconductor integrated circuit, wherein said method comprises:

• generating a data indicating a basic cell and a data indicating each of cells of a cell group different in logic from said basic cell;
• and
• storing the data indicating said basic cell and the cells of said group cell indicating data in a library of a storage unit,
• wherein an outer shape and a position of a wiring pattern of each cell of the cell group are same as those of said basic cell,
• the wiring pattern of said basic cell and the wiring pattern of each cell of said cell group contain a wiring obstruction section indicating an area (OBS;
• Obstruction) in which a passage wiring is inhibited, and
• when a design change is carried out, said basic cell is replaced by a change cell of said cell group in response to said design change.
