Integrated circuit with multiple cells having different heights

摘要

An integrated circuit comprises a first cell having first cell height and a first line routed at a first line height and having a first line width. The integrated circuit also comprises a second cell having a second cell height different from the first cell height and a second line routed at a second line height and a second line width different from the first line width. The integrated circuit further comprises a third cell. The third cell has a third line having a first end and a second end. The first end has a first end width. The second end has a second end width. The first end width is equal to the first line width. The second end width is equal to the second line width. The first end is coupled with the first line. The second end is coupled with the second line.
