METHODS, SYSTEMS, AND ARTICLES OF MANUFACTURE FOR IMPLEMENTING PHYSICAL DESIGN DECOMPOSITION WITH CUSTOM CONNECTIVITY

Disclosed are methods, systems, and articles of manufactures for implementing physical design decomposition with custom conductivity by identifying custom, incomplete conductivity for an electronic design, partitioning a physical design space multiple non-overlapping cells, and iteratively moving at least some of the nodes of these multiple cells to generate a floorplan or a placement layout until one or more convergence criteria are satisfied while maintaining the custom, incomplete conductivity. The floorplan or a placement layout generated resembles the final floorplan obtained through a floorplanner or the final placement layout through a placement tool without requiring that complete conductivity information be provided to the floorplanner or placement tool.
