Abstract:
A method for redistributing cell densities in layout of IC is provided. Initial cell density distribution and routing density distribution are obtained in an initial placement of the IC. White space is inserted into the initial placement according to a specific density value, so as to flatten the initial cell density distribution to the specific density value and obtain a flat cell density distribution. The specific density value is larger than a maximum cell density value within the initial cell density distribution. Cell densities of a first region are increased in the IC according to the routing density distribution and the flat cell density distribution, so as to obtain a modified cell density distribution. The modified cell density distribution is smoothed to obtain a calibrated cell density distribution. The white space is removed from the calibrated cell density distribution to obtain a final placement.

Claim (Index 12):
The non-transitory computer-readable storage medium as claimed in  claim 9 , wherein a layout area of the final placement is smaller than a layout area of the initial placement.
