POWER LINE PLACEMENT STRUCTURE FOR MACRO CELL AND STRUCTURE FOR JOINING MACRO CELL TO POWER MESH

摘要

A power line layout of a macro cell includes power lines arranged on a plane of the macro cell in a diagonal direction. A combined layout of a macro cell and a power mesh includes a power mesh on which first power lines are formed in a vertical direction and a macro cell having internal circuit elements on which second power lines for providing a power voltage to the plurality of internal circuit elements are formed in a diagonal direction. The first power lines are electrically coupled to the second power lines at intersections between the first and second power lines when the macro cell is arranged to overlap with the power mesh. Accordingly, when the power lines of the macro cell are combined with the power lines of the power mesh, the intersections between the power lines of the macro cell and the power mesh may be easily formed.
