Title: Placement of structured nets

Abstract: Mechanisms are provided for performing placement of cells in a design of a semiconductor device. An initial design of the semiconductor device is generated, the initial design comprising a first placement of cells. A preferred direction of placement associated with the cells is determined. The preferred direction is a direction along which spreading of the cells is preferred. A second design of the semiconductor device is generated by modifying the first placement of the cells to generate a second placement of cells, different from the first placement cells, based on the preferred direction of placement associated with the cells.
