Abstract:
A semiconductor integrated circuit device in which a plurality of input/output cell groups each comprising a plurality of input/output cells for performing signal transfer with an external device are each arranged in a loop so that an internal logic circuit area is surrounded by a plurality of loops,wherein a bonding pad for performing signal transfer with the external device is provided in each of the input/output cells of inside and outside input/output cell groups of the plurality of input/output cell groups, wherein first guard bands are disposed on an internal logic circuit area side of the bonding pad in each of the input/output cells of the inside input/output cell group, wherein said input/output cells of the inside input/output cell group are arranged in a condition where a first space for providing wiring between the internal logic circuit area and the input/output cells of the outside input/output cell group is provided, and wherein said inside input/output cell group and said outside input/output cell group are arranged in a condition where a second space for providing wiring between the internal logic circuit area and the input/output cells of the outside input/output cell group is provided.
