Automated Bottom-Up and Top-Down Partitioned Design Synthesis

An embodiment of the present invention includes a partitioner, a synthesizer, and an optimizer. The partitioner partitions a design into a hierarchy of partitions having a top-level partition and lower partitions. The lower partitions include a bottom-level partition. The top-level partition has top-level constraints. The synthesizer synthesizes the lower partitions hierarchically from the bottom-level partition to create lower partition netlists based on the top-level constraints. The optimizer optimizes a top-level netlist corresponding to the top-level partition from the lower partition netlists to satisfy the top-level constraints.
