Abstract

To increase the efficiency of electronic design automation, execute partition-aware global routing with track assignment on an electronic data structure including a small block floorplan of a putative integrated circuit design. The small block floorplan is virtually partitioned into a proposed large block floorplan with a plurality of inter-large-block boundaries of a plurality of large blocks. Based on results of the executing, determine locations, on the inter-large-block boundaries, of a plurality of required ports corresponding to routes identified in the routing, as well as required sizes of the ports. Generate a physical partitioning based on the inter-large-block boundaries; align the ports with the inter-large-block boundaries; and generate a hardware description language design structure encoding the physical partitioning.
