Patent attributes
Approaches for placing and routing a circuit design on a programmable integrated circuit (IC) are disclosed. One partial reconfiguration (PR) resource portion of the circuit design is selected from a plurality of PR resource portions of the design. Uncontained resources in the PR resource portion is identified. The PR resource portion, less the uncontained resources, is placed in an assigned region, and the uncontained resources is placed on the programmable IC unconstrained by the assigned region of the PR resource portion. The design is routed from the placed PR resource portion to the placed uncontained resources, and the process is repeated for each unplaced PR resource portion. After placing the plurality of PR resource portions and routing to uncontained resources in the plurality of PR resource portions, unplaced portions of the circuit design are placed and routed.
