Method and apparatus for diffusion based cell placement migration |
摘要 |
A method for cell placement in an integrated circuit design that uses a calculated diffusion velocity determined from a density value in order to relocate the cells until the cell placement reduces the density below a predetermined threshold. The method acts to control the movement of different cells to reduce the density of the cells prior to legalization of the cell placement.
