LAYGEN – Automatic Analog ICs Layout Generator

This paper describes an innovative analog IC layout generation tool based on evolutionary computation techniques. The designer provides a high level layout description. This template contains placement and routing constrains and is independent from technology. This expert knowledge is used to guide an evolutionary optimization kernel during the automatic generation of the layout for the target technology. Additionally, this template can be used hierarchically in the definition of templates for more complex circuits. The LAYGEN tool is here presented and demonstrated for the layout generation of typical
