IC layout editor

An Integrated circuit layout editor or IC layout editor is an electronic design automation software tool that allows a user to digitize the shapes and patterns that form an integrated circuit. Typically the view will include the components (usually as pcells), metal routing tracks, vias and electrical pins. Software of this type is similar to computer aided drafting software, but is specialized for the task of integrated circuit layout. The typical flow for the layout of analog circuits might be :
In some cases the layout engineer will request minor changes to the schematic to simplify the layout.
