Integrated circuit based on grid and method of designing the same

An integrated circuit comprising:

• a plurality of cells arranged in a grid configuration having a first pitch,
• wherein the grid comprises a plurality of grid lines arranged in a first direction based on the first pitch and extending in a second direction crossing the first direction,
• wherein the plurality of cells comprise:
• a first cell comprising first gate lines respectively overlapping first grid lines among the plurality of grid lines, each of the first gate lines extending in the second direction;
• and
• a second cell comprising at least one second gate line overlapping second grid lines among the plurality of grid lines, the at least one second gate line extending in the second direction,
• wherein the first pitch corresponds to a pitch of the first gate lines, and
• wherein a first length of each of the first gate lines in the first direction is less than a second length of the at least one second gate line in the first direction.

An integrated circuit comprising:

• a plurality of blocks arranged in a grid configuration having a first pitch;
• and
• a first metal layer on the plurality of blocks,
• wherein the first metal layer comprises a plurality of first metal lines, each extending in a first direction and arranged apart from each other in a second direction crossing the first direction,
• wherein the first pitch corresponds to a pitch of the plurality of first metal lines, and
• wherein the grid comprises a plurality of grid lines extending in the first direction and arranged in the second direction based on the first pitch.
