ABSTRACT:
An apparatus of preventing congestive placement is provided. The apparatus comprises a judging module, a pattern generating module, and a placement module. The judging module judges whether a circuit layout comprises a congestive region according to a judging rule. When a judgment result of the judging module is affirmative, the pattern generating module generates a redistribution pattern with a density distribution of blockages. The density distribution gradually decreases outward. The placement module regards the congestive region as the center redistributes the blockages and electronic cells according to the redistribution pattern.
