Abstract
This paper describes an innovative analog IC layout generation tool, LAYGEN II, based on evolutionary computation techniques. The designer provides the high level layout guidelines through an abstract layout template. The template contains placement and routing constrains independently from technology, and can be used hierarchically in the definition of templates for complex circuits. LAYGEN II uses this expert knowledge to guide the evolutionary optimization kernels during the automatic layout generation in the target technology. The routing task of the proceeding can range from a template-based approach to a full automatic generation, if only connectivity is provided. The LAYGEN II tool is demonstrated for the layout generation of two typical analog circuit structures and the results validated by Calibre® design rule check tool.
