PURPOSE:To greatly shorten a design interval by effecting simultaneously designs of electronic circuit blocks by dividing the upper surface of a semiconductor chip to many mats of the same size by means of partition lines and incorporating a plurality of electronic circuit blocks of different functions onto an integer number of the mats. CONSTITUTION:The upper surface of a semiconductor chip 1 is halved into first and second regions 3, 4 substantially of the same shape by making use of a division region 2 indicated by a double-dot line, and the respective regions 3, 4 are divided into mats A-J and K-T. Partition lines 5 partition the respective mats from each other. The partition lines 5 allow power supply lines and ground lines to extend parallel adjoining thereto. For arrangements of the power lines and the ground lines which constitute the partition lines 5, the power supply lines are provided on the left sides of the respective mats A to J and K to T as indicated by solid lines, while the ground lines are provided on the right sides as indicated by dotted-chain lines. Accordingly, only the partition lines located on opposite ends of the first and second regions 3, 4 are formed ones of the power supply lines or the ground lines, and the intermediate partition lines are constructed with both lines. |
