Abstract
In one embodiment a new method to address configuring a logical design and libraries of design elements with additional information is proposed that may be used to create a physical design from that logical design. Logical designs may be generic, while physical design libraries are normally targeted towards specific technology. Consequently, there can be a mapping from the cells in a logical library to cells which correspond to their implementation in a physical library. In one embodiment, annotations required to map from logical design to physical design may be stored in a separate design view. In one embodiment the user can modify the physical mapping attributes of cells, instances, and occurrences in the logical design and save the modifications back to the physical configuration view.
