Abstract

We present an interactive two layer router integrated in an analog IC design environment used in an SDL (schematic driven layout) design flow. Special features are its customizability, the treatment of arbitrary polygons and an advanced handling of source/target polygons in order to avoid net internal design rule violations during connection phase. A global routing algorithm is used to split the route into separate parts each routable in a single layer. After via placement a specialized maze router performs the advanced single layer routes in 90 or 45 degree mode. The resulting route can be modified by interactive via movement and rerouting of obsolete partial routes
