基于等位线的自动布局系统

AUTOMATIC PLACEMENT SYSTEM BASED ON EQUIPOTENTIAL LINE

本文所讨论的是一种模拟电路的自动布局系统，由于模拟器件具有不同的尺寸与形状，为此本文把元器件的外接矩形作为它的布局边界以进行单元划分。并且，提出了等位线的概念，使得不同形状器件的布局问题转化为具有相同形状单元的布局问题。

This paper discusses an automatic placement system of analog circuits.Since analog modules have a great variety of size and shape, by using the circumscribed rectangle as the placement boundrary, the circuit can be easily partitioned. The concept of equipotential lines are proposed,the placement with irregular modules can be transformed into the placement with uniform cells.
