In this report I formulate analog layout constraints and survey the state of the art of automatic analog layout systems, which can handle only few analog constraints, and generate less dense layout. To solve these problems I propose a new interactive analog layout methodology. It provides topological editing in the geometrical view based on Rubber-band routing. The purposes of this new methodology are i)to overcome the difficulty of control the layout parasitic elements with irregularities of analog devices and wiring effects and ii)to reduce the analog VLSI design period. After describing new concepts for that interactive methodology, I state some specific challenges.
