Abstract

A method of generating a layout design of an integrated circuit. The method includes forming a first region having at least two first-type cell rows extending in a first direction. Each one of the first-type cell rows has a first row height measured along a second direction perpendicular to the first direction. The method also includes forming a second region having at least two second-type cell rows extending in the first direction. Each one of the second-type cell rows has a second row height measured along the second direction. The first region is adjacent to the second region, and the first row height of the first-type cell rows is different from the second row height of the second-type cell rows.
