LEF to OA

In this flow, LEF layout information is imported to generate an abstract layout view.

This flow lets you import an existing LEF abstract generated by a non-Cadence tool and use the advanced features of Abstract Generator to render the data for use in Cadence floorplanning and place-and-route engines, particularly power routers. For example, you might use Abstract Generator to form correct power geometry groupings into LEF PORTS for sroute.

The abstract view can be used directly in the Virtuoso Studio design environment or you can export LEF 5.x for use with Innovus.
