Abstract
A semicustom semiconductor IC device is structured by connecting together various types of initially prepared macro cells in a given combination in accordance with a circuit configuration, and requisite characteristics, requested by a user. A plurality of signal terminals are provided on some sides of at least one of the macro cells to enable a signal corresponding to the same group of signal terminals to be input or output. Of those signal terminals to be connected, associated signal terminals of the shortest connection distance are selected so that they are connected together by a corresponding shortest connection wire.
