摘要: 提出一种新的有限圆族包络(FCM)自动化建模方法:变深度包络法。该方法针对现有自动化建模方法在不重叠约束满足方面的不足,协同考虑布局组件尺寸与包络深度二因素,在包络圆近似模型中实现不重叠约束的精确表达。实例对比表明,变深度包络法不但能够较不完全包络法有效减少组件包络圆数目,简化布局优化预处理结果,且与不完全包络法相比,能够杜绝组件之间的重叠现象,避免最终布局结果错误的发生。

Abstract: A new Finite Circles Method(FCM) automated modeling algorithm:the varying approximation degree algorithm is proposed.By taking components size and approximation degree into account,this new algorithm overcomes the shortcomings of the existing FCM automated modeling algorithms,satisfies the non-overlapping constraints accurately.As examples show,the approximation models which are generated by this new algorithm not only build fewer circles than the region-wide approximation algorithm,simplify the approximation results,but also eliminate the overlapping problems which occur in the half-region-wide approximation algorithm,avoid layout errors.
