ИСТИНА

A method for selectively placing cells of an application-specific integrated circuit on a substrate surface, including the steps of defining a grid covering a substrate surface, assigning cells to the grid to provide old x and y coordinates of the cells relative to the grid, grouping the cells by function to provide functional regions within the grid, determining a density map of the surface of the substrate in all the functional regions within the grid, determining free space of the grid on the surface of the substrate relative to the density map, and assigning new cells to the free space of the grid on the substrate surface to provide an application specific integrated circuit. Use of the method provides improved layout of an integrated circuit with minimal cell congestion or overlapping.
