Abstract
A method of designing a semiconductor device includes: (A) dividing a layout region of a semiconductor chip into matrix by a unit region; and (B) determining an interconnection layout such that an occupation ratio of a high-density region to the layout region is less than 50%. Here, the high-density region is a set of the unit regions in each of which interconnection density is higher than a predetermined reference value.
Claims12
A method of designing a semiconductor device using design program recorded on a non-transitory computer-readable medium, comprising:
- (A) dividing a layout region of a semiconductor chip into matrix by a unit region;
- (B) determining an interconnection layout such that an occupation ratio of a high-density region to said layout region is less than 50%, said high-density region being a set of said unit region in which interconnection density is higher than a predetermined reference value;
- and
- (C) dividing said high-density region into a plurality of divided high-density regions and modifying said interconnection layout by distributing said plurality of divided high-density regions to said layout region.
A design program recorded on a non-transitory computer-readable medium that, when executed, causes a computer to perform a process comprising:
- (A) dividing a layout region of a semiconductor chip into matrix by a unit region;
- (B) determining an interconnection layout such that an occupation ratio of a high-density region to said layout region is less than 50%, said high-density region being a set of said unit region in which interconnection density is higher than a predetermined reference value;
- and
- (C) dividing said high-density region into a plurality of divided high-density regions and modifying said interconnection layout by distributing said plurality of divided high-density regions to said layout region.
